Preparation

Basic settings of the test

·Programming Interface: SWD

·Serial port settings: Select a proper COM port, configure as follows:

Baud rate:115200;

Data bits:8;

Stop bits:1;

Parity bits: None;

Flow control: None

·Power supply: 5V power supply is required.

·Hardware Connection: For the tests that require the serial port converter for debugging, please connect the

converter to the board via pin headers, and then connect it to the PC via USB cable;
