7i76E one PWM needed

Hello,

I have a 7i76E card setup and running. Now I need a PWM generator to control a L298 H-bridge.
I've already install the Xilinx software and I'm able to compile bit files. Which PIN file is supplied with the 7i76e file when it's shipped?
Is it possible to add one PWM generator and have PWM functionality on one of the GPIO pins? How should I proceed?

Kind regards,

Chris

PIN_7i76x1D_51.vhd is the pin file used for creating the default 7I76E config
You would need to add the PWM to one of the expansion port pins (or steal a step/ dir pin if you dont need all 5)

I only use three stepgen generators so I can use the fourth for PWM. I'll give it a try this evening.

I've got it working! Thanks for your help!

Regards Chris

That's great. Its a really big help when people can make their own custom bitfiles

(I realize not everyone can or wants to do this)

Hi,

I ran into a little annoying issue. When I close Linuxcnc or turn off the PC the PWM value will go to 100% (5V). How can I change this behaviour so it will be 0% (0V)?
