Mesa 7i71 - Stepgen on Digital Output for ATC

That should be no Problem.
I will have to rename them in the HAL file then, right ?
Also is there a way to use RS485 on the 7i52S ?

Thanks in advance

 

Had issues making it fit so:

P1 7I33 Normal encoders and numbering
P2 7I52 Just 2 stepgens
P3 7I44 just 4 sserial ports

Had forgotten how small XC2S200 chips are...
A wee bit more may fit if you need something desperately
 

Thanks for your efforts, I will try this firmware.

For future proofing, are there newer alternatives for PC104 formfactor than the 4i65 which are supported ? I Liked the pcie connection to the fpga so far, as it was super stable all time. Or should i consider a ethernet connected board like 7i80HD-25 or similar for the future ?

Hey Peter,
I tested the firmware you provided.
The 7i33 and the 7i44 + connected SSerial Devices work properly,
but I have Problems getting the Stepgens on the 7i52S to work.
Maybe im getting something wrong, but when entering a value to .postion-cmd, shouldnt the Stepper move?

The Stepper driver is connected to COMM0:

Pin3 TX0A to Step-
Pin4 /TX0A to Step+
Pin5 TX0B to Dir-
Pin6 /TX0B to Dir+

Do you have the 7I52S TXEN0 set low?

A 50 pin FPGA card option would be a 6I24 (PCIE) or 7I80HDT (Ethernet)

I read about it in the 7i52S manual, but wasn't sure how to do it.
Like so ?

I also tried the second Port COMM1 which shouldn't need that setting, right?
That one also didnt produce output to the stepper driver

Thanks for the info about those two boards, so theres no future proof board for the external pcie cable connection.
