Power Supply: If the microcontroller is having issues, first check the power supply. There may be a problem with the power supply. Use a multimeter to check the power supply voltage of the microcontroller; it is best to use an oscilloscope to capture the voltage waveform because the voltage may be unstable (for example, voltage … Read more
1. Reset (1) What is Microcontroller Reset The reset of the STM32 microcontroller refers to the process of resetting the microcontroller to its initial startup state. The reset behavior causes all running programs to terminate and restores the microcontroller’s registers and functions to their initial values. The reset process provides a known starting state for … Read more
