Hi,

Thanks for the reply but I still don't know what to configure. The code in pwm_lld.c seems to support TIM12 as other timers, and the code in pwm_lld.h relating to timers are mostly error handlers, after configuring them things didn't turn out to be better.

It is not matter of configuring ...

Hi,

Not all timers are supported in all drivers, the change you made is not sufficient, just look for the STM32_PWM_USE_TIMxx macros in pwm_lld.c and pwm_lld.h files, that will reveal all places where changes are necessary.

Hi,

I'm trying to output PWM wave from a port using TIM12. Previously I succeeded in doing so on a port using TIM8, by the following code(or sth. like that):

PWMConfig pwm8cfg = {
100000, /* 1MHz PWM clock frequency. */
1000, /* Initial PWM period 1ms. */
NULL,
{
{PWM_OUTPUT_ACTIVE ...
