Enable clock out Due to the requirement of low power, every module of stm32 microcontroller uses the clocks independently So, when we use a peripheral, we must enable its clock firstly. Otherwise, it will not work 1010 Enable clock out Due to the requirement of low power, every module of STM32 microcontroller uses the clocks independently.
