Hi,

I am working on STM32F4 version of microcontroller. Can someone guide me the way to generate PWM signal. I may want to use atlease 2 PWM out signal and 1 PWM in signal.

The purpose of generating PWM signal is to control the DC MOTOR SPEED.

I have searched few method which are not suffucient for me to understand clearly. I am still in confusion where to start to generate PWM signal from STM32F4xxx

Please suggest me any resource which will provide step by step tutorial.

Thanks,

Farhan

Hi Farhan,

I recommend you to have a look to the TIM examples under the STM32F4 cube firmware some of them show how to configure the TIM peripheral to generate PWM signals:

Hello Nesrine

In the file you recommanded in TIM folder there is PWMInput and PWMOuput.. which one shall I use when I want to generate pwm for LEDs pleaase ??

Thank you in advance for your help
