How to implement the program for PWM generation in stm32f051c8t6tr

jm.2 · ‎2022-11-10

I working on stm32 microcontroller, I want to generate the pwm signal for stm32f051c8t6tr mcu.

I have assigned my prescalar as 48-1 and counter period is 1000-1 in order to generate 10KHz frequency.

My code is

TIM1->CCR1=50;

HAL_TIM_PWM_Start(&htim1,TIM_CHANNEL_1);

The above two code only i tried but i am not getting any output. Can you please me, how to solve this issue

Thanks

Hello @jm.2,

Could you please share the STM32CubeMX configuration 🙂

Basic LED blinky works?

Check, if you have continuity from mcu to the pin where you are measuring. The simplest way is to do a "blinky" on that pin, i.e. turn the pin to GPIO output and toggle it.

Other than that, read out and check/post the TIM and relevant GPIO registers content.

Note that TIM1 is Advanced Timer thus needs to have TIM1_BDTR.MOE set.
