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

Merry Christmas to everybody. I would like to thank everybody for their support in making the firmware and driver last year.

Wish everybody good days and stay safe!

Today I finally merged and deleted the branch 'envoders' in which I was developing the support for encoders. Tested the working for encoders successfully and put everything in main. Some nice facts / features on the encoders:

• In the JSON-config you can set minimum and maximum value for the encoders. This plays really nice for setting feed, rapid and spindle override. You can directly use the output of the encoder counts with gmoccapy or you can use the scaled value to simulate an potentiometer with this function 
• In the JSON-config you can set the reset_value. This is the value to which the counts are set on the FPGA when either the FPGA is being reset (for example at start up of LinuxCNC) or when the index enable is set to TRUE and an index pulse happens.
• A breakout board for fast encoders is available. The speed aimed for is 1 MHz.

Now I'm going to focus to solder more of my breakout boards and actually finish the EMCO5 with it. Please come with issues or suggestions either here or in the  issue list  and they will be looked in to.
 

My 5a-75e is ff-up. Does any one in Europe, or even better in The Netherlands, have a spare card? It takes so long to get a new one otherwise.

Update:
Just ordered two more cards. Spend more then 8 hours trying to rewire the broken traces and fix the buffers. But I think some more of the board has been damaged, because I cannot get any response from the JTAG. Either something shortened out in the FPGA and had it fried, or something else is terrible wrong which I cannot solve.

The new boards will arrive on 15th of January (if everything goes well), then I'll be back in business. 

Hello together, i am a beginner at this point. I have one Question - can i use this board (5a75b) also only for stepper motors without encoder feedback?
Kind regards

Surely. Moreover, if you don't need even digital inputs you can run 5A-75B without any hardware modifications.

Yes, with normal step/dir drives.
