# TTGO T-Display
|
||
|
||
## Quick start
|
||
|
||
1. **Install USB driver**, [CHxxx Series MAC driver](http://www.wch-ic.com/downloads/CH34XSER_MAC_ZIP.html) , [CHxxx Series Windows driver](http://www.wch-ic.com/downloads/CH343SER_ZIP.html),[CP21xx Series driver](https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads)
|
||
2. Copy **TFT_eSPI** to the **<C:\Users\Your User Name\Documents\Arduino\libraries>** directory
|
||
3. 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
|
||
1. 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
|
||
2. Finally, click upload, the right arrow next to the tick
|
||
|
||
-------------------------
|
||
1. **安装 USB 驱动**, [CHxxx Series MAC driver](http://www.wch-ic.com/downloads/CH34XSER_MAC_ZIP.html) , [CHxxx Series Windows driver](http://www.wch-ic.com/downloads/CH343SER_ZIP.html), [CP21xx Series driver](https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads)
|
||
2. 拷贝 **TFT_eSPI** 到 **<C:\Users\你的用户名\Documents\Arduino\libraries>** 目录内
|
||
3. 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
|
||
4. 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
|
||
5. 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
|
||
6. 最后可点击上传即可,勾号旁边的向右箭头
