Bitfile for rcservo - MESA 7i95t

Hi all,I'm using a Mesa 7i95T and I need a bitfile with the following configuration:
  • sserial on P1 (to read a MESA 7i87 for analog sensors)
  • 1x rcpwmgen for RC servo control (MG995, 50Hz, 1-2ms pulse width)
  • as many stepgens as possible with the remaining pins (ideally 5)
Currently I'm using
Code:
7i95t_1pwmd.bin
which has a standard pwmgen, but rcpwmgen would be much cleaner for direct RC servo control without needing external offset/scale calculations. Is there an existing bitfile that covers this, or could you compile one?Thanks in advance!

I could add 2 RCPWMs to replace one Step/dir channel

Not sure what you mean about the sserial channel on P1
The 7I95T typically has 2 sserial channels on TB4

Thanks it should work fine with the 2 RCPWMs and the sserial on TB4

Firmware for a 7I95T with 2 RC PWMgens replacing the last (05) step/dir pins:
