In last video, we have understood clearly about generating a PWM signal at timer output channels.
Today we can do a LED dimming program using the same PWM feature of the stm32 controller. We will be increasing and decreasing (controlling) brightness of the LED on the Nucleo board.
The amazing fact is you don't need an additional LED or any other circuit to do this project.
Just your Nucleo board will do this magic!

Nice explanation. Wishes to continue your work.
Thanks a lot😊
very good video, it changes to bare métal coding!!
Thanks Guillaume!
We are still playing with HAL libraries. We can do a session exclusively with Bare-metal coding if you're interested🙂.
Can you also put a video on implementing this on controlling dc motors?
Yes. I'll try to post that👍
@@vdevelop Can you tell me why have you enabled the auto-reload preload ?
Cant PWM pulse be generated by simply inserting PSC/ ARR values?
Merci
de rien
How do you control the brightness of the LED using a Potentiometer
1. Read pot value using analog channel
2. Do necessary scaling to get the duty cycle, and update the pwm duty cycle
can you do a video about
HAL_StatusTypeDef HAL_TIM_PWM_Start(TIM_HandleTypeDef * htim,uint32_t Channel )
HAL_StatusTypeDef HAL_TIM_PWM_Stop(TIM_HandleTypeDef * htim,uint32_t Channel )
sorry i think i see it in the previous videos
