Hey there :)I am having trouble running the nucleo (NUCLEO-U5A5ZJ-Q) as an I2C slave where read/write sizes are unknown (only known by master)For the configuration I am using CubeMX and most of the time the slave is working quite fine. However someti...
PWM frequency is not as expected
Hi,I'd like help to understand what is thew PWM frequency.As far as I understand:1. The main system clock is 64MHZ -- see below SystemClock_Config()2. PWM frequency is 64KHz (= 64MHZ / (1000 - 1))BUT, measuring the frequency shows 4KHz (rather than 6...
