Posted on May 03, 2016 at 06:34Greetings all
I'm using HAL_TIM_PWM_ConfigChannel() to set the Pulse value for my PWM output but I want to modulate it (think IR LED on/off keying) so I'm currently using HAL_TIM_PWM_Start() and HAL_TIM_PWM_Stop(). The latter leaves the output in a high impedance state which causes the output to drift around falsely turning on a MOSFET driver.
Can I directly manipulate the output using the GPIO registers or are they totally disabled due to the mode being set to GPIO_MODE_AF_PP (alternate function) or is there a recognised way I can do this with minimal overhead (preferably staying with the HAL)?
