The CH347 multi-functional interface demonstration software is an open-source debugging tool that integrates six core functions: SPI, I2C, JTAG, SWD, UART, and GPIO. It comprehensively covers the core communication protocols and peripheral control scenarios of the CH347 chip. Each chapter of the software demonstrates the functions of each interface. The I2C interface implements temperature and humidity sensor data acquisition, the JTAG and SWD interfaces complete program download and...
