I'm using stm32f4 discovery with HAL drivers to realize a Synchronous BOOST DCDC.
When the system is turn on, the gpio PE8 and PE9 configured as PWM pins of TIM1,(in particular PWMOUT_CH1 & PWMOUT_CH1N) goes in SET state and for a few milliseconds keep the mos of the converter in ON state causing a little initial short circuit.
At startup PE8 and PE9 are in high impedance state?
If so,can i avoid this issue with a 100k pull down resistors?
There are software solutions to this problem?
