Hi @mxo I can't find the ___HAL_TIM_SET_COMPARE function on the PWMOutput sample codeI tried changing #define PULSE1_VALUE (uint32_t)(1000 / 2) to #define PULSE1_VALUE (uint32_t)(50000 / 1) and it outputs 76% but I don't understand code work logic. 

Hi MXO,I can't understand how to join your code,The definitions provided by your code and example code seem to be different.

Hi Stassen, Thanks for your reply.But I have a question,I find this code but I can't understand how to change the PULSE_VALUE,example code is output PWM has a 90% duty cycle, if change 50% duty cycle how to set the PULSE_VALUE?
