The tutorial mainly introduces the components of the STM32 minimum system.
Minimum system composition
The STM32 minimum system is mainly composed of power supply circuit, clock circuit, reset circuit, debug circuit (serial port download circuit) and main control chip
Power supply circuit: provides the required power supply voltage for the entire circuit system;
Clock circuit: provides the required clock signal for MCU;
Reset circuit: provides a unified initial state for MCU;
Debug circuit: provides an interface for program download and debugging for MCU.
Main control chip
The main control chip of the development board used for the balance car is STM32F103RCT6, which is a high-performance microcontroller based on the ARM Cortex-M3 core launched by STMicroelectronics.
