USB IO module

Anyone ever find out a source for the USB IO module that Tormach uses? So far I've only found one that's similar and it might be possible to make it work, but it's a definite might.

Looking at how PP communicates with the board there are Tormach specific strings in it.

I would tend to believe that the board is either custom tormach or a commercial board that has been customized by Tormach.

it send the command VE and gets back two values, r and data, data contains the "Tormach I/O"

this is contained in the usbio.py file

A bit of recoding in the usbio.py probably could make this work with other boards.

the other thing you can do is you can map in the hal file I/O directly. i did this for 4 outputs as a test

At one time (last year) the IO module was a CP2102 with 4 relays attached.

It's a CP2102, a microcontroller, and four relays (output) plus four optocouplers (inputs) plus an ID selector.

If you're comfortable rolling your own, I reverse-engineered the protocol, and wrote firmware for the Teensy 3.2/3.5 microcontroller (Arduino-like but harder/better/faster/stronger) that emulates the USB I/O: github.com/jwatte/teensy_tormach_usbio

It can also be used on an Arduino Leonardo with minor changes, I've heard, but it doesn't work well on a "plain" Arduino because the serial bootloader gets in the way of properly detecting the board.

thank you for this. I figured that someone probably had done this before. I was going to eventually look into this myself, but this works too.

I seen this on youtube..




Found the board in the video on amazon..
