ColorCNC Colorlight 5A-75E/5A-75B as FPGA controller board

Btw adding —build to the colourlight_5a_75b.py command will run the build script as well. If it fails it is usually because stepgen.v isn’t in build/gateware directory.

If you follow my instructions, you don’t need to install migen as a seperate item.

What is the vendor and product id of your programmer ?
 

I ran colorlight_5a_75b.py before set path, probably this is explanation.

The programmer is still in bag, because I have dispute with seller.
I don't know vendor and id, but have photo :
 

I have a feeling that might work, I use an Altera USB Blaster clone works fine with openfpgaloader, which is included with oss-cad-suite

At this moment I'm trying to make the idea of ColorCNC more flexible and expandable to more ColorLight cards. Therefore I started LiteX-CNC based on the contributions.

Trying to:
- configure the card by a JSON file (click-and-program);
- firmware split over multiple files for better readability and expansion with new functions;
- supports all ethernet FPGA cards which are supported by LiteX.

It is still work in progress (only GPIO out is finished at this moment) and not tested as my card is not yet in.

The repository can be found here: github.com/Peter-van-Tol/LiteX-CNC

Are you going to document the changes required to get any form of input ? I can document the way I'm going to implement my procedure if you like.

I have a 5A-75E so I will be willing to help in testing, if you have any a build environment ready, eg any make files, are you going to be using the pluto based stepgen source as per Romanetz ?
ATM I'm waiting for some 74LVC245 buffers to arrive.

If you could document your approach on enabling the inputs on a 5A-75E or 5A-75A, you're more then welcome. For the i5 and the i9 there are no changes required as far as I know.

The build files for the driver are available in the ./driver/build directory of the repo. However, the driver is in debug mode and will not transmit anything yet. I will create a separate debug driver (dumps everything to command line) and tidy up the ethernet driver so you should be able to test.

For building an image for the card, one could use the code below as an guideline (assuming you've installed the LiteX toolchain as described here ):
This will generate the files which can subsequently be uploaded to the board.
