I already used the PIO, but it's not working.

when I load my circuit into the FPGA.

i didn't see the result that I want.

It also depends from what type of interface your pwm circuit has.

If it has a plain n-bit input port which directly set the pwm duty cycle, then it should work connected to pio.

If it has a specific bus interface (addr,data,wr,rd,ce,...) then your sopc must provide the same interface in order to set the required registers
