hello

im working with a nucleof103 and the cubeMX HAL library.

i managed so far to get a steady pwm out via tim3_ch1 on PA6.

but id like to change the DC after each periode, therefore enable interrupts and change then the registers value. but so far, i did not find any function from the HAL library except to completely reinit the entire timer structure. i guess i have to write the the register directly. i dont know yet which one, do i have to write my new pulse width to the ARR or the CCR register?
