01:22 AM polprog: rue_mohr: thanks, ill be looking for ft232 with these today at the bazar
01:57 AM polprog: https://upload.wikimedia.org/wikipedia/commons/b/bf/Inside_fibre_cab_%2812945979503%29.jpg
01:57 AM polprog: i wonder what terminal block type is that, on the right
06:50 AM rue_shop2: HUAWEI system
06:50 AM rue_shop2: (??)
06:50 AM rue_shop2: england
06:51 AM rue_shop2: so if I say 0.5V
06:51 AM rue_shop2: from 5V
06:52 AM rue_shop2: -20db
06:53 AM rue_shop2: but -34db might be getting towards a limit anyhow
06:54 AM rue_shop2: -40db is probably all I'd ever get
08:42 AM zhanx_laptop is now known as zhanx
09:30 AM polprog: rue_bed: i was to get a pci riser like that, but on a tape
09:30 AM polprog: whats that huge card ?
09:38 AM polprog: ok, i found one that seems to have all the pins of an ft232rl broken out
10:25 AM Tom_L: well what you waitin for then?
10:47 AM polprog: well, i just ordered em
10:47 AM polprog: should be in two days
02:44 PM polprog: hmm, got two floppy drives, one alps and one samsung. the alps one is a bit dicky
02:44 PM polprog: but at least i have two known good spares now
03:09 PM Tom_L: who uses floppy drives anymore?
03:16 PM polprog: i know rues lawnmower does
03:16 PM polprog: ive got a couple of computers that do, for $0.75 a piece i thought ill get a spare
04:24 PM rue_mohr: polprog, well, I thought the drive was dieing on the tek754
04:24 PM rue_mohr: and yesterday if crashed on me twice
04:25 PM rue_mohr: so I started to panic as I thought the drive might be completely shot
04:25 PM rue_mohr: I took the drive out, discovered its a pcmcia drive
04:25 PM rue_mohr: but I put the scope back togthor without it
04:25 PM rue_mohr: and the bad-head-clicking noise was still there, but the scope worked fine
04:25 PM rue_mohr: so
04:26 PM rue_mohr: so I put the drive back in, but have no idea if I'm in trouble or not
04:27 PM Tom_L: it has a hdd in it?
04:27 PM rue_mohr: yes
04:27 PM Tom_L: don't know what the noise was ehh?
04:27 PM rue_mohr: but it looks like its just used for storing trace data as a save option
04:27 PM rue_mohr: I think its the internal front end relays
04:28 PM rue_mohr: it sounds like a hard drive thats head magnets are going
04:28 PM Tom_L: huh
04:28 PM Tom_L: yeah
04:28 PM rue_mohr: *clunk clunk* *clunk clunk*
04:28 PM rue_mohr: I'm worried tho
04:28 PM rue_mohr: cuase it still did crash
04:28 PM rue_mohr: I was googling last night
04:28 PM Tom_L: is that why they were selling it?
04:28 PM rue_mohr: it looks like ram problems are common
04:29 PM Tom_L: hmm
04:29 PM rue_mohr: I think they were selling it cause people want newer scopes
04:29 PM Tom_L: socketed or soldered?
04:29 PM rue_mohr: these things have a reputation of lasting forever, and being servicable
04:29 PM rue_mohr: their flash chips, 16 and 32M
04:29 PM rue_mohr: I'd love to be able to back them up
04:30 PM rue_mohr: or do a firmware upgrade (reflash the chips)
04:35 PM rue_mohr: oooh
04:36 PM rue_mohr: the adc might be shared on this thing
04:36 PM rue_mohr: I was starting to think it could do 4x 2Gs channels
04:39 PM Tom_L: what sort of flash chips?
04:39 PM Tom_L: wonder if that flash chip hack i did ages ago would work
04:40 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/mtkflash/flash_howto_index.php
04:43 PM rue_mohr: smt flash chips

04:43 PM rue_mohr: wtf with links these days!?!?
04:43 PM rue_mohr: https://forum.tek.com/viewtopic.php?f=568&t=139999&hilit=TDS784/
04:43 PM rue_mohr: maybe that will work
04:44 PM Tom_L: probably so they can monitor traffic
04:45 PM Tom_L: can't figure out why my isp is so friggin slow lately
04:45 PM rue_mohr: thats enough data for a base64 gif animation
04:45 PM Tom_L: takes a long time to resolve the address it seems
04:45 PM rue_mohr: cloudflare
04:45 PM rue_mohr: the worlds worst proxy service
04:46 PM Tom_L: wish my board would arrive..
04:46 PM rue_mohr: did you get the programmer for it?
04:46 PM rue_mohr: or we gonna have another polprog going on here
04:46 PM rue_mohr: ;)
04:49 PM rue_mohr: I need to go do some outside things
04:49 PM rue_mohr: GM wants to fix up the truck, and I'm kinda reserved, but...
04:52 PM polprog: lol
04:52 PM polprog: rue, if it was a pcmcia, you can easily fit it with a CF card
04:52 PM polprog: also, ordered the ft232RLs
05:02 PM Tom_L: my jtag should work on it
05:02 PM Tom_L: i hope...
05:02 PM polprog: thats what i said
05:03 PM Tom_L: no, i've used this one before just fine
05:03 PM polprog: me too
05:03 PM polprog: i know, im joking
05:03 PM Tom_L: on xilinx chips
05:05 PM Tom_L: polprog, you got connectors etc to make up your cables?
05:06 PM polprog: no, i was hoping to get some IDCs at the market today but the folks who have these were out
05:06 PM polprog: ill grab some at a second source tomorrow
05:06 PM polprog: thansk for reminding me
05:06 PM polprog: i need single goldpin shrouds/whatever you call these
05:06 PM polprog: mostly
05:07 PM rue_mohr: polprog, connectors from the front panel of an old computer
05:07 PM Tom_L: i got bags of male.female to build those up
05:07 PM polprog: not enough old computers
05:07 PM rue_mohr: remember, DO NOT HOOK UP THE 5V TO THE VCC OF THE FPGA
05:07 PM polprog: yes, i even made up a sticker
05:07 PM polprog: on it
05:07 PM Tom_L: not many shrouds but you can heatshrink around them
05:07 PM rue_mohr: :)
05:08 PM * polprog currently fighting entropy
05:08 PM rue_mohr: polprog, old computers are one of the most common commodities
05:08 PM Tom_L: i'm kinda wondering about that on mine since it will use a ribbon connector on this new board.
05:08 PM polprog: actually
05:08 PM rue_mohr: you can walk into any office and say "where is the pile of old computers" few people will say they dont ahve one
05:08 PM Tom_L: i'll check the voltages at the jtag first
05:09 PM polprog: i wanted to make up a universal labeled jtag cable, so thats what i neded the single headers for
05:09 PM polprog: like your partport blaster
05:09 PM rue_mohr: there is no standard jtag pinout
05:09 PM rue_mohr: so I put individual shrouds on mine
05:09 PM polprog: thats why every pin has to be separate
05:09 PM polprog: yes
05:09 PM Tom_L: my local electronics guy went under so i'm kinda lost for a source now too
05:09 PM Tom_L: i got lots of 10cond ribbon left though
05:09 PM rue_mohr: why the hell someone coulnd't have suggested a standard pinout I'll never know
05:09 PM rue_mohr: even avr has two
05:10 PM polprog: i could make an only for fpga cable though now from the in shop stuff
05:10 PM polprog: well, they made
05:10 PM polprog: and then someone made another one
05:10 PM rue_mohr: :) three if you count the oopsed schamatic of that programmer everyone made
05:10 PM polprog: like, that 20 pin jtag is crazy
05:10 PM polprog: there are *more* grounds than signals
05:11 PM rue_mohr: I wonder how the hd44780 pinout became a standard
05:11 PM polprog: hmm
05:11 PM polprog: yes, who let that slip under
05:11 PM polprog: unacceptable
05:15 PM polprog: i believe the pack of vfd should come tomorrow
05:18 PM polprog: https://allegro.pl/oferta/konwerter-usb-rs232-ttl-ft232rl-zestaw-arduino-avr-8299524832
05:18 PM polprog: this is the one i got
05:18 PM polprog: it has all the pins broken out
05:19 PM polprog: "self assembly kit" where you need to solder on the header and usb, lol
05:22 PM rue_mohr: ok
05:23 PM rue_mohr: how did the price compare with the chineese one?
05:23 PM rue_mohr: you operate in a place with strange currencies
05:23 PM polprog: 22 pln is 5.50 usd
05:24 PM rue_mohr: so better cool
05:24 PM rue_mohr: and its closer isn't it?
05:24 PM Tom_L: rue_mohr, how's your govt feel about that down'ed plane?
05:24 PM polprog: yes, i reckon that they send from poland
05:24 PM Tom_L: since most were canadian...
05:24 PM rue_mohr: dunno
05:24 PM rue_mohr: "canadian"
05:24 PM rue_mohr: I wonder
05:24 PM polprog: most of these people are just aliexpress proxies but i dont have to wait
05:25 PM rue_mohr: I suspect they were immigrant canadians
05:25 PM Tom_L: i think they said most were students
05:25 PM rue_mohr: could be
05:25 PM Tom_L: i don't watch the news, i get it 2nd hand
05:25 PM rue_mohr: could be immigrant canadian students too
05:26 PM rue_mohr: I'v not heard about any town grieving over the loss of a school of students
05:26 PM rue_mohr: but what I can tell
05:26 PM rue_mohr: is that *SOMEONE* is trying to start a war, and, I dont actually fully believe its trump
05:26 PM polprog: rue_mohr: strange enough to have gamepad symbols on the notes: https://www.wykop.pl/cdn/c3201142/comment_JN6SuhmYyDwInuMN3Gw4vu4rTQ5C2wUK.jpg :^)
05:27 PM polprog: are you talking about that ukrainian plane? or which one?
05:27 PM rue_mohr: heh OR shapes?
05:28 PM rue_mohr: Tom_L, I also think there is a LOT of fake news going around
05:28 PM Tom_L: i'm sure of that
05:28 PM Tom_L: that's why i don't watch it
05:30 PM rue_mohr: I'm pretty sure trump doesn't have much of an army, cause they didn't get paid or support or anything
05:30 PM Tom_L: don't kid yourself
05:31 PM rue_mohr: lots of stories of US mil cheques bouncing
05:31 PM rue_mohr: homeless vets
05:32 PM Tom_L: the vets aren't taken care of that well i agree
05:32 PM Tom_L: but i doubt they are anywhere
05:32 PM rue_mohr: so
05:32 PM rue_mohr: I need to make a folder
05:32 PM Tom_L: once they're done with them, they're of no use
05:32 PM rue_mohr: I got the lcd timing sequence done for that lcd
05:33 PM polprog: what chipset is that LCD?
05:33 PM polprog: ive got 3 huge copier LCDs..
05:33 PM rue_mohr: LM200
05:33 PM rue_mohr: OLD
05:33 PM polprog: i could try to RE the connector, there are markings on the ICs
05:33 PM rue_mohr: but new ones work much the same way
05:33 PM Tom_L: polprog, those are likely graphic
05:33 PM polprog: i remember Lambda was talking to me about them
05:33 PM Tom_L: harder to work wiht
05:33 PM polprog: Tom_L: thats right
05:33 PM rue_mohr: :) the ackronym RE got me or a while when I first corssed it
05:34 PM polprog: reverse engineer?
05:34 PM polprog: :P
05:34 PM rue_mohr: yea
05:35 PM polprog: they are.. about 25cm diagonally
05:36 PM rue_mohr: their LM200?
05:36 PM polprog: no, i dont think so
05:36 PM polprog: let me get one
05:36 PM rue_mohr: wait, is LM200 a screen or chipset...
05:36 PM polprog: i didnt take pics of them
05:36 PM polprog: yet
05:36 PM rue_mohr: I think its the screen pn
05:38 PM X704 is now known as tiwake
05:39 PM tiwake: do you guys have a good tutorial for the atmega 328?
05:39 PM rue_mohr: can make one on the fly
05:39 PM rue_mohr: what do you want to do, flash the led?
05:39 PM rue_mohr: like 'getting started' ?
05:40 PM rue_mohr: <timeout>
05:40 PM tiwake: like, iunno, I'm imagining a C programming book but for atmega stuff
05:40 PM polprog: thats a bad approach
05:41 PM rue_mohr: lets make one
05:41 PM rue_mohr: do you have an atmega328 based arduino board?
05:41 PM tiwake: I don't want to use that
05:42 PM rue_mohr: you dont have to use arduino
05:42 PM rue_mohr: but an arduino is the cheapest way to get an avr
05:42 PM rue_mohr: and it has the support circuitry on it
05:42 PM rue_mohr: an arduino is just an avr on a breakout board
05:43 PM rue_mohr: (that has a serial bootloader you dont have to use)
05:43 PM tiwake: actually this looks good https://www.sparkfun.com/tutorials/93
05:43 PM tiwake: I was looking at this earlier https://www.youtube.com/watch?v=wopmEyZKnYo
05:44 PM rue_mohr: buying the dip actually costs more than a chineese arduino
05:44 PM tiwake: I have a tube of 25 of them already XD
05:44 PM rue_mohr: ah!
05:44 PM rue_mohr: ok
05:44 PM tiwake: and a whole bunch of other random stuff that I got
05:44 PM rue_mohr: so, you need a programmer, have anything already?
05:44 PM tiwake: though I forgot to get some quartz crystals
05:45 PM polprog: rue_mohr: https://polprog.net/rozne1/ircjunk/
05:45 PM tiwake: ...or did I?
05:45 PM rue_mohr: see how the arduino is a nice shortcut?
05:45 PM polprog: you dont need the crystals, unless you pulled the dips from an arduino
05:45 PM polprog: uno to be precise
05:45 PM rue_mohr: polprog, there will be datasheets for those
05:46 PM rue_mohr: or if you blow the fuse programming
05:46 PM polprog: rue_mohr: im sure, ill go look, last time i touched that display i was below legal age for drinking
05:46 PM rue_mohr: polprog, that might be the same chipset...
05:47 PM polprog: found datasheet for M5278 ic, that seems to be the brains and the rest is just drivers
05:47 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/graphicsLCD/p1140768.jpg <-- see the timing diagram?
05:48 PM polprog: rue_mohr: XOFF
05:48 PM rue_mohr: polprog, yea, there are typically row and column drivers, the column drivers are just huge shift registers
05:48 PM polprog: gimme a sec :P
05:48 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/graphicsLCD/FLM_start.png
05:48 PM rue_mohr: there is fpga output
05:48 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/graphicsLCD/FLM_end.png
05:48 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/graphicsLCD/zoomout.png
05:48 PM Tom_L: tiwake, it's old but still valid: http://tom-itx.no-ip.biz:81/~webpage/how_to/atmega168/mega168_howto_main_index.php
05:48 PM rue_mohr: thats all the signals are spec'd in the datasheet
05:49 PM rue_mohr: took me like an hour on the fpga
05:49 PM rue_mohr: tiwake, do you have a prgrammer?
05:49 PM rue_mohr: ^^ retry on that q...
05:50 PM rue_mohr: Tom_L, I was so thrilled to get that
05:51 PM Tom_L: get what?
05:51 PM tiwake: I have two
05:52 PM Tom_L: the logic analyzer?
05:52 PM tiwake: rue_mohr: I think what is bothering me the most is how I don't seem to understand the "c" code when I've done C programming in the past...
05:52 PM rue_mohr: yea, the 64 bit ersion of LOGIC
05:52 PM rue_mohr: tiwake, excellent tell us what they are
05:53 PM Tom_L: i haven't updated mine in quite a while
05:53 PM Tom_L: the software
05:53 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/graphicsLCD/blink.v
05:53 PM rue_mohr: all sorts of new tricks
05:53 PM Tom_L: explain why assign is better?
05:53 PM rue_mohr: does nto involve a latch
05:54 PM rue_mohr: aka, does not have to be clocked
05:54 PM Tom_L: i see
05:54 PM rue_mohr: <= is for things clocked into latches (I think)
05:54 PM Tom_L: that's alot of inputs n outputs for a blinky :)
05:55 PM rue_mohr: I didn't clean up
05:55 PM * Tom_L moons moon
05:55 PM MoonyMoon: yes
05:55 PM rue_mohr: I'm leaving a lot of mud in my wake
05:55 PM MoonyMoon: YES YOU ARE
05:55 PM Tom_L: u sure are
05:55 PM rue_mohr: MoonyMoon, you dressed today?
05:55 PM tiwake: rue_mohr: also, if I declare an unsigned integer, is it unsigned 8 bits or unsigned 16 bits?
05:55 PM polprog: rue_mohr: i found the shift reg inputs
05:55 PM MoonyMoon: yes
05:55 PM MoonyMoon: I am
05:55 PM rue_mohr: polprog, let me get a pic of those chips
05:56 PM polprog: your chips?
05:56 PM Tom_L: rue_mohr, why do you assign them at the bottom?
05:56 PM rue_mohr: its the last mental thing for me to do
05:57 PM rue_mohr: I'm sure the position doen't matter
05:57 PM Tom_L: probably not
05:57 PM rue_mohr: polprog, yea, chippics
05:57 PM rue_mohr: not dippics, these are smd
05:57 PM Tom_L: what's the 239 represent?
05:57 PM rue_mohr: 240 lines
05:58 PM rue_mohr: its a 240x64 display
05:58 PM rue_mohr: but it breaks the screen into 2 32 line sections
05:58 PM rue_mohr: (there are two data lines)
05:58 PM rue_mohr: tiwake, excellent tell us what they are (2nd attempt)
05:59 PM polprog: i wonder if i could hook it anduse buspirate to send clocked data.. id need to guess the supply voltage[s]
06:00 PM Tom_L: display?
06:00 PM rue_shop2: HD44104
06:01 PM Tom_L: what you got hooked to it
06:01 PM tiwake: meh, maybe it would make more sense if I start looking at the datasheet
06:01 PM rue_shop2: but I have other displays
06:02 PM rue_shop2: M5260
06:02 PM rue_shop2: and 5278...
06:02 PM rue_shop2: see if I have any of those
06:02 PM Tom_L: graphic?
06:02 PM rue_shop2: yea
06:02 PM Tom_L: huh
06:02 PM rue_shop2: but more awkwardly, no storage
06:02 PM rue_shop2: you have to stream to it
06:02 PM tiwake: at this point I don't really have time to set up and really sit down to look at this stuff... maybe next weekend
06:03 PM Tom_L: spi, i2c?
06:03 PM rue_shop2: tiwake, you will never have time
06:03 PM rue_shop2: tiwake, and if you are not acually sitting down and doing it, it will never happen
06:03 PM tiwake: well, this weekend I had plenty, but was sick, and throughout the week was working 12 hour days
06:03 PM rue_shop2: happy to walk ya thru it
06:03 PM polprog: rue_shop2: heads up i moved the images to another dir
06:03 PM rue_shop2: make sure ya have a camera
06:04 PM rue_shop2: noticed
06:04 PM tiwake: yeah, and I have a good one :P
06:04 PM rue_shop2: irc needs pointless not-quite-what-you-want emojii and image/video paste like twit
06:05 PM polprog: why, we can just [s]ftp images to our servers
06:05 PM rue_shop2: twitter is so handy, select, upload...
06:05 PM rue_shop2: and the video translation stuff
06:05 PM rue_shop2: cause, nothing can do a video format that isn't (webbrowser)
06:05 PM polprog: im sure lambda would know the supply voltage from the top of his head
06:06 PM rue_shop2: good news, I have 5278 in my pdf repo, so there are good chances I have a screen with one
06:06 PM tiwake: rue_shop2: and much before that I didn't have all the electronic components needed (the capacitor, resistor, LED, diode, and similar) packs I ordered hadn't come in yet
06:06 PM polprog: 5V and 8-20V. hm
06:06 PM Tom_L: polprog, what are you in school for?
06:06 PM rue_shop2: tiwake, arduino, cheap
06:06 PM tiwake: futurlec likes to take their time... heh
06:06 PM polprog: Tom_L: photonics
06:07 PM Tom_L: fun
06:07 PM polprog: yep
06:11 PM tiwake: there is a crap ton of other crap I gotta do, for sure
06:13 PM tiwake: should I get a variac?
06:14 PM Tom_L: what for?
06:14 PM rue_shop2: polprog, nope dont see any
06:14 PM polprog: any what? pics?
06:14 PM rue_shop2: tiwake, you have to make an led flash first
06:14 PM rue_shop2: and its not about the flashing led, its about the toolchain to do it
06:14 PM tiwake: I guess my own bench power supply/testing
06:15 PM tiwake: rue_shop2: yeah...
06:15 PM rue_shop2: dont have any screens with your chipset I cant find
06:15 PM rue_shop2: tiwake, your getting too commplex
06:15 PM rue_shop2: get a chineese arduino pro mini, mega328 based
06:15 PM tiwake: I just don't like the bench power supply that I have
06:15 PM rue_shop2: then work out to where you have to do all the wiring yourself
06:15 PM rue_shop2: Tom_L, funny thing
06:16 PM tiwake: hmm, I guess I could still make it work
06:16 PM rue_shop2: one of the *types* of copier lcd's I have, has a spartin on it

06:17 PM rue_shop2: tiwake, you should get a pro mini and a programmer (you might alreayd have) and make an led flash
06:17 PM tiwake: really the first thing I should do, is pull out all the components, put them in drawers, and label them
06:18 PM rue_shop2: no
06:18 PM tiwake: lol
06:18 PM rue_shop2: tiwake, you should get a pro mini and a programmer (you might alreayd have) and make an led flash
06:18 PM tiwake: its all a jumbled pile of mess right now
06:18 PM rue_shop2: then ponder what to do after that and get what you need
06:18 PM tiwake: :P
06:18 PM rue_shop2: tiwake, ti doesn't matter cause you dont need any of it cause you cant do anything yet
06:18 PM tiwake: I already bought the draws for it

06:19 PM rue_shop2: polprog, I must have a screen around with a 5278
06:19 PM tiwake: it was the sparkfun pocket programmer... did a couple things with atmega controllers... I just don't really remember it
06:20 PM rue_shop2: ^^ Tom_L made an awesome programmer
06:20 PM rue_shop2: tiwake, find it
06:20 PM rue_shop2: thats what you need to do, FIND the programmers
06:20 PM rue_shop2: thats what you need to do, FIND the programmers
06:20 PM rue_shop2: thats what you need to do, FIND the programmers
06:21 PM tiwake: heh, I have both of them in my hand
06:21 PM rue_shop2: Tom_L, its hooked to a S1D13503, which I think is an lcd controller
06:21 PM rue_shop2: tiwake, good take a picture and post it
06:21 PM Tom_L: rue_shop2, i dunno how big that fpga is or if it's a cpld instead
06:22 PM Tom_L: xc may indicate cpld
06:22 PM rue_shop2: oh
06:22 PM tiwake: this one https://www.sparkfun.com/products/9825
06:22 PM tiwake: and
06:22 PM rue_shop2: why "spartin" tho?

06:22 PM rue_shop2: tiwake, hold on a sec
06:22 PM tiwake: https://www.sparkfun.com/products/12942
06:22 PM rue_shop2: tiwake, figure out and set up posting YOUR OWN pictures
06:22 PM rue_shop2: this is part of getting help on doing it
06:23 PM tiwake: I'm going to clean up my mess first, before hooking up wires and crap
06:23 PM rue_shop2: tiwake, forget the bus pirate, use the other one
06:23 PM rue_shop2: install "avrdude"
06:23 PM tiwake: its like cleaning the kitchen before cooking
06:24 PM Tom_L: who does that?
06:24 PM tiwake: I do... lol
06:24 PM * rue_shop2 starts hitting tiwake with a wiffle bat "THERE ARE NO WIRES TO HOOK UP YET!!!"
06:25 PM tiwake: one time I was at a friends house, they asked me to cook, "sure", but then the kitchen was really messy... spent 2 hours cleaning the kitchen before starting to cook for them
06:25 PM Tom_L: so did you cook dinner or breakfast?
06:25 PM tiwake: it was funny... they were watching a movie and complaining about being hungry "well come help me clean the kitchen and it will get done faster", but they never did
06:25 PM tiwake: it was dinner time
06:27 PM polprog: rue_shop2: cool
06:27 PM polprog: im getting closer to figuring out the voltages onmine
06:33 PM rue_shop2: "S1D13503 Graphics LCD Controller"
06:34 PM polprog: ??
06:34 PM rue_shop2: The S1D13503 is a dot matrix graphic LCD controller supporting resolutions up to 1024x1024. It is
06:34 PM rue_shop2: capable of displaying a maximum of 256 simultaneous colors out of a possible 4096 or 16 gray shades.
06:34 PM rue_shop2: Design flexibility allows the S1D13503 to interface to either an MC68000 family microprocessor or an
06:34 PM rue_shop2: 8/16-bit MPU/bus with minimum external logic. The Static RAM (SRAM) interface used for the display
06:34 PM rue_shop2: buffer is optimized for speed and performance, supporting up to 128K bytes.
06:34 PM rue_shop2: this HP lcd I have
06:34 PM polprog: ah
06:34 PM rue_shop2: oh this is funny
06:34 PM rue_shop2: Tom_L, I think the spartin is a serial to parallel converter
06:35 PM polprog: ok, i made https://polprog.net/rozne1/ircjunk/xerox_lcd/notes.txt
06:35 PM polprog: ill hit the bed now
06:35 PM polprog: gn
06:35 PM polprog: well, eat something beforehand
06:35 PM rue_shop2: cause it has a 16 bit parallel interface on a board with a serial connection
06:35 PM Tom_L: huh
06:35 PM Tom_L: easy enough to do on one
06:36 PM rue_shop2: pin 11 will probably be contrast then polprog
06:36 PM polprog: likely
06:36 PM polprog: or the VR1 pot is that
06:36 PM polprog: see you tomorrow o7
06:37 PM Tom_L: bye
06:37 PM rue_shop2: haha
06:37 PM rue_shop2: 19 address lines, 16 data lines, /rd /wr...
06:37 PM rue_shop2: hahaha
06:37 PM rue_shop2: nowonder there are so many wires going to it
06:38 PM rue_shop2: it looks like 3 lines go from the board connector to the spartin
