- Copy TFT_eSPI to the <C:\Users\Your User Name\Documents\Arduino\libraries> directory
- Open Arduino IDE, find TFT_eSPI in the file and example, the T-Display factory test program is located at TFT_eSPI -> FactoryTest, you can also use other sample programs provided by TFT_eSPI 3 In the Arduino IDE tool options, select the development board ESP32 Dev Module, select Disable in the PSRAM option, select 4MB in the Flash Size option, Other keep the default
- Select the corresponding serial port. If you are not sure, please remove all the serial ports, leaving the board in the USB connection state, just select that one
- Finally, click upload, the right arrow next to the tick
- 拷贝 TFT_eSPI 到 <C:\Users\你的用户名\Documents\Arduino\libraries> 目录内
- 打开ArduinoIDE , 在文件，示例中找到TFT_eSPI, T-Display出厂测试程序位于TFT_eSPI -> FactoryTest,你也可以使用其他TFT_eSPI提供的示例程序
- 在Arduino IDE 工具选项中 ， 开发板选择 ESP32 Dev Module,在PSRAM选项中选择Disable， Flash Size 选项中选择4MB ，其它保持默认
- 选择对应的串行端口，如果不清楚请移除所有串行端口，之保留板子处于USB连接状态，选择那一个即可
- 最后可点击上传即可，勾号旁边的向右箭头
- Demonstrate how to use the second SPI device, using the SD card as a demonstration device
- 使用SD卡作为演示设备,演示如何使用第二个SPI设备
