So
Thank you for explanations.
Get it to work nice but I'm struggling to increase the resolution to 2000. My duty is only 50% even if I send the value 2000. Already changed all records for 11-bit anyway.

but changing the subject, I made a move to take advantage of the outputs that might be useful for you too.
I used the first bit of register 6A directional bit as if it is 1 then the remainder is stored in the register of the PWM parameters, but is usually stored as control of the DIO.

Still does not work perfectly, because reading does not work right.
The code is attached. I hope it helps you too.

regards

Fabio

Fabio,
1) I didn't erased at all the older pads, I just added some new, and assigned their pins the ones of the older pads. But if you want to generate more than 1 pwm, I already replaced 7 pins, just look for them. One is seleccion_pad (I guess) and the other one is the bus pwm (which has 6 outputs already placed).
2) I used the 75Mhz frequency clock because I needed a 75khz and I decided to have 1000 resolution. However, you can change the code so the 100Mhz clock drives the pwm, and you could have a faster frequency.

Hope it helps.
Regards,
Enrique
