Generate 10us single pulse triggered by software

[huzeifa]

Hello,

I would like to generate a 10us wide single pulse using the hardware Timer 1 peripheral that can be triggered by software. Currently, I am setting a pin as GPIO output and manually setting the pin high and low. I was wondering if there was an option with hardware timers. Can some one guide me on how to achieve this with CubeMX and HAL library. Thanks

For example

while(1)

{

  HAL_Delay(1000);
  Send_Pulse();

}

Hi,

Just look in RM or in Cube for timer -> one pulse mode.

Maybe this doing what you want.

Hello @huzeifa, 

As @AScha.3 said, OPM allows the timer to generate a single pulse with a programmable length after a programmable delay. You can find cube examples following STM32CubeF4 in GitHub 

Also, refer to AN4776 section 3, N pulse waveform using one pulse mode. 

Hope that helps!
