06:57 PM polprog: didnt decide what CPU to use yet
06:57 PM polprog: s/CPU/MCU
06:59 PM rue_mohr: is that a standard serial pinout?
06:59 PM polprog: yeah, cisco kind
07:04 PM rue_mohr: cool
07:05 PM rue_mohr: ok, well, am I tired?
07:05 PM polprog: Ive never designed an ethernet connection, i hope i got it right
07:05 PM rue_mohr: did you use the applications circuits from all the datasheets?
07:06 PM rue_mohr: did you make the traces like you see on ethernet stuffs??
07:06 PM polprog: i didnt make the traces yet, i found some application circuit
07:06 PM polprog: s
07:06 PM rue_mohr: k
07:06 PM polprog: funnily enough the 3 laptop schematics i have all use magjacks
07:06 PM rue_mohr: yea, I'm tired
07:07 PM rue_mohr: pull apart an old 10/100 switch
07:07 PM rue_mohr: or 10M hub >:/
07:07 PM rue_mohr: or... whats this thing???....\
07:07 PM * rue_mohr holds it up by the cord
07:08 PM polprog: no dont grab them by the cord
07:08 PM polprog: they will bite you
07:10 PM * rue_mohr holds it out as far as his arm will allow
07:11 PM rue_mohr: /8\
07:11 PM rue_mohr: /8-\
07:11 PM rue_mohr: so
07:11 PM rue_mohr: network to serial
07:11 PM rue_mohr: did I tell you about my esp8266 idea?
07:12 PM polprog: no
07:12 PM polprog: also it has both network and serial
07:13 PM polprog: its gonna take SCPI commands over telnet
07:13 PM polprog: and the serial console is there for initial network config and diagnostics
07:34 PM rue_mohr: polprog, !
07:34 PM rue_mohr: no better
07:34 PM rue_mohr: I have a javascript/html serial terminal!!!!
07:35 PM rue_mohr: to back onto an 8051!!!
07:35 PM rue_mohr: running basic!
07:37 PM polprog: lol
07:37 PM polprog: yesss
07:39 PM rue_mohr: and actually I want to make an interface to my bigtrak emulator
07:39 PM rue_mohr: but I can use an SVG with buttons and internal links
07:39 PM rue_mohr: same basic idea
07:40 PM rue_mohr: if you want, I have a javascipt console interface mostly done out
07:40 PM polprog: hmmm
07:40 PM rue_mohr: screenshot?
07:40 PM polprog: thats a feature creep for that project but i could use it somewhere else
07:40 PM polprog: sure
07:44 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/Untitled.png
07:44 PM rue_mohr: interested?
07:45 PM rue_mohr: oh its just 1 file, ok
07:45 PM polprog: looks nice!
07:45 PM rue_mohr: it was a lot of fighting with css
07:47 PM polprog: css is like that
07:47 PM rue_mohr: http://ruemohr.org/%7Eircjunk/programming/Main.html
07:47 PM rue_mohr: heh, it will, of course, open
07:47 PM rue_mohr: if you..
07:48 PM rue_mohr: reset is intended to be hardware reset of target
07:49 PM rue_mohr: ....?
07:50 PM rue_mohr: it looks like I dont have the enter key hooked up to the text input
07:51 PM rue_mohr: iirc, the only way to do that is to add a filter on every key pressed
07:52 PM polprog: looks OK to me
07:53 PM rue_mohr: hey, your project is esp8266
07:53 PM rue_mohr: wish I had someone to hack with
07:54 PM polprog: my project is crazy, i bought these w60 led controllers and they have that esp8266 for network connectivity
07:54 PM Tom_L: the good ole days...
07:54 PM polprog: and a TZ32Fsomethingsomething for led driving
07:54 PM rue_mohr: fpga?
07:54 PM polprog: and i cant for the love of god figure out how to connect to the TZ32
07:54 PM polprog: maybe? im thinking it's an STM32 clone
07:54 PM rue_mohr: oh
07:55 PM polprog: the pinout would match..
07:55 PM rue_mohr: try to flash it with some test code
07:55 PM polprog: but its not responding to stlink, and jtag
07:55 PM rue_mohr: ah
07:55 PM rue_mohr: cause of *the jumper*
07:55 PM polprog: the what?
07:55 PM rue_mohr: 2 boot jumpers
07:55 PM polprog: oh god
07:55 PM polprog: let me test that
07:55 PM polprog: hey i should make that reverse engineering repo public actually
07:55 PM rue_mohr: or I'm thinking stm32?
07:55 PM rue_mohr: you said that
07:56 PM rue_mohr: ok
07:56 PM polprog: let me see the boot0 boot1 pin stae
07:56 PM polprog: state*
07:56 PM rue_mohr: yea
07:56 PM rue_mohr: that
07:57 PM rue_mohr: well anyhow
07:58 PM rue_mohr: i wish css had a way to only show the scroll bars if there was content that needed scrolling
07:59 PM polprog: overflow property
08:00 PM rue_mohr: overflow: scroll;
08:00 PM rue_mohr: but its always showing the scroll bars
08:02 PM polprog: boot0 has floating voltage on it around 0V
08:02 PM rue_mohr: Tom_L,
08:03 PM rue_mohr: polprog, what happens if I overload you with too many things you want to do at once?
08:03 PM polprog: im overloaded already
08:03 PM rue_mohr: :)
08:13 PM rue_bed: I should work on a bigtrak interface SVG
08:37 PM polprog: goodnight
09:19 PM Tom_L: ?
09:38 PM rue_mohr: did you not hear about me writing bigtrak control software for bots?
09:39 PM Tom_L: no
09:39 PM rue_mohr: oh
09:39 PM Tom_L: i dunno
09:39 PM Tom_L: maybe
09:40 PM Tom_L: i saw something about making code shorter
09:40 PM rue_bed: that was for the knock sensor to turn the desk light on and offf
09:41 PM rue_bed: dont know why it doens't technically fit on the controller I used it on
09:41 PM rue_bed: why is my cat meowing...
09:41 PM rue_bed: gnight
09:41 PM Tom_L: gnite?
09:41 PM Tom_L: ok
