Use Arduino IDE

1. Install the correct serial port driver CP210X Driver
2. Change src/main.cpp to src.ino
3. Copy the files in the lib directory to ~/Arduino/libraries, Windows users copy to Documents/Arduino/libraries
4. Double-click to open src/src.ino
5. Change the port to the correct port and select upload

Use PlatformIO

1. Install the correct serial port driver CP210X Driver
2. Open directly to change your serial port in platformio.ini, click compile

• Note: To use TFT_eSPI, you need to select the correct model, you need to select Setup26_TTGO_T_Wristband.h, which has the same definition as T-Wristband, If the copy is in the lib folder, you can ignore it

Examples Description

In the examples directory contains two sample programs, FactoryTest is the factory test file, HeartRateMeter is a simple heart rate meter. You need to change the program. You only need to copy the files in the directory to the src directory. Arduino IDE needs to be renamed to src.ino, and PlatformIO can be opened and compiled directly
