0.1.3 合宙CORE-ESP32-C3开发板用arduino点亮ST7735 1.8寸TFT屏【已更新失效链接2022.07.10】_?萌新历险记_ardu

网络 02-07 7943

9.9的ESP32开发板想用arduino开发，无奈都是用luatos玩，于是折腾了下

?目的

用arduino驱动合宙ESP32-C3开发板点亮S7735TFT屏

材料

CORE-ESP32-C3开发板*1

ST77351.8寸TFT屏128*160分辨率*1

连接

实施

1、配置ESP32环境

在不丢失ESP8266的情况下，打开arduino-文件-首选项，附加开发板管理器网址

在原ESP8266的网址后面加逗号“,”

https://arduino.esp8266.com/stable/package_esp8266com_index.json,https://·/package_esp32_index.json

保存，然后发现下载不了环境，直接下载离线包

在此我要特别感谢 arduino中文社区提供的小白资源，我这个萌新差点就卡死在该死的GITHUB了，附上源链接，CSDN要是封了我就直接注销这平台了Arduino IDE安装esp32 SDK（Windows）2022.7.6更新-Arduino中文社区 - Powered by Discuz!

下载完不用打开arduino，直接安装，安装完成后打开就看到开发板列表了，安装自动匹配路径

波特率921600，flashmode选 DIO2接下来下载tft_espi，在库路径编辑......\Arduino\libraries\TFT_eSPI-2.4.61的user_setup.h文件

注意IO口是按开发板丝印的GPIO口来的并不是按ESP32pin脚来的

根据自己的TFT屏分辨率，是否带触摸进行配置，以上代码是按1.8寸128*160分辨率TFT ST7735屏更改的，对应开发板排线不用交叉调的GPIO口，

3打开示例，开发板选ESP32-C3 DEV MODULE ,编译刷入，不出意外直接点亮
