07:21 PM rue_mohr: I have to studdy a bit more today
07:21 PM rue_mohr: most of this course section is about knowing a verry particular VFD
07:27 PM Tom_L: i'm kinda wondering what a certain plug on mine is
07:27 PM Tom_L: it's not in the manual
07:27 PM Tom_L: i'm kinda thinking it might be modbus

08:12 PM rue_mohr: ok
08:12 PM rue_mohr: I have to try to work out what the instructor has been trying to get us to know
08:13 PM rue_mohr: which is basically the background of what we need to know to navigate configuring the vfd the course is based on
08:13 PM rue_mohr: understanding braking types and how the accel/decel params work
08:14 PM rue_mohr: I think by friday you will have your VFD
08:15 PM rue_mohr: huh, deadlock, dont know which thing to work on
08:15 PM rue_mohr: power supply, what stopped me
08:16 PM rue_mohr: the encoder filters

08:16 PM rue_mohr: i always resent not having used optical encoders
08:16 PM Tom_L: change colors
08:16 PM rue_mohr: I wonder how much it would take me to use your disks and replace the chineese ones
08:16 PM rue_mohr: wow
08:16 PM rue_mohr: I could, its part of the RGB direction
08:17 PM rue_mohr: where is that?

08:25 PM rue_mohr: example
08:25 PM Tom_L: i've never tried that
08:26 PM Tom_L: so it could start the mill software on boot
09:05 PM MoonyMoon: rue_mohr: !
09:05 PM MoonyMoon: what lang do you FPGA with?
09:09 PM Tom_L: verilog or vhdl
09:09 PM Tom_L: verilog is easier to follow
09:10 PM Tom_L: both are similar
09:11 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/xilinx/New_Board/
09:11 PM Tom_L: some examples
09:11 PM Tom_L: .v or .vhd files

09:28 PM rue_mohr: Tom_L, which software did we use?
09:31 PM Tom_L: pretty sure you used verilog
09:31 PM Tom_L: some of yours is in that 2nd link

10:23 PM rue_mohr: d
10:23 PM Tom_L: first interesting thing in the log i found
10:24 PM Tom_L: https://polprog.net/rozne1/ircjunk/gal/
10:24 PM Tom_L: must be all of it
10:25 PM Tom_L: odd language
10:26 PM Tom_L: enough there to keep you busy at least for tonight
10:30 PM rue_mohr: yea this is about the right level of thinking for me tonigt
10:38 PM rue_mohr: Tom_L, whats the language called there?
10:39 PM Tom_L: no idea
10:40 PM Tom_L: gasm?
10:40 PM rue_mohr: ...
10:40 PM Tom_L: https://github.com/daveho/GALasm
10:41 PM Tom_L: My setup:
10:41 PM Tom_L: - A GAL assembler for compiling stuff. I went with https://github.com/daveho/GALasm , it's
10:41 PM Tom_L: a modern linux port of an Amiga program of the same name
10:41 PM Tom_L: - A means to program the GAL chip. I already had a TL866, and the minipro(1) linux utility
10:41 PM Tom_L: can read JEDEC files (files produced by GALasm are not compatible, more on that later)
10:41 PM Tom_L: You could also make up a parport wiggler, other universal programmers should be able to do
10:41 PM Tom_L: GALs as well.
10:42 PM rue_mohr: yea
10:42 PM rue_mohr: but...
10:43 PM rue_mohr: ok, instead of answering the question, I'll just delete it
10:44 PM Tom_L: gnite
10:46 PM rue_mohr: gnight
10:46 PM rue_mohr: polprog, when you wake up, that page seemed to have almost all the details, I'm just re-wrapping them a bit.
11:11 PM rue_mohr: polprog, what I still don't know, is the exact PAL part number you used, surely it was an erasable one, PALC16V8 ?
11:13 PM rue_mohr: polprog, did you have to ground pin 11? (/OE)
