MM32F103C8T6 to 89C52 board

Overview

The adapter board can supply power to the learning board, but the learning board cannot supply power to the adapter board. MM32F103 to 89C52 board power supply circuit.png The external high-speed clock circuit refers to the schematic diagram of the development board officially provided by MM32. The external high-speed clock circuit of STM32 cannot be used directly. The two R4 and R6 A resistor is essential (unless an external high-speed clock circuit is not used). MM32F103 external high-speed clock circuit.png The startup method is fixed to start from the main flash memory, so the program cannot be downloaded using the serial port download method.
