Solved - 0-5 V PWM with Mesa 5i25/7i76 possible? was created by caban
I need a 0-5 V modulation for a laser driver.
How can that be realized?
TB4 is unused until now.
Can somebody help me with the code?

Here is a bitfile for the 5I25/6I25 that replaces Stepgen 4 with a PWM gen

I have flashed the bit file and reboot the card.
Readhmid shows me 2 PWM Module.
But on the configuration page, the value is always reset to zero.
Is there something wrong, or is the PWM different named?

Pncconf Doesn't know about the PWM generators so you must set them up and connect them in the hal file.
Also even if pncconf knew about the PWM, it does not know how to use it as a modulation source
