1 硬件描述
我这里用的LCD是RGB接口的，驱动IC为ST7701S，用ESP32S3驱动，RGB565 16根数据线，接线如下：
| ESP32S3 | LCD | SPI数据线 |
|---|---|---|
| IO48 | SDA | SPI数据线 |
| IO16 | SCK | SPI时钟线 |
| IO15 | CS | SPI片选线 |
| IO14 | PCLK | RGB时钟线 |
| IO13 | DE | RGB数据使能 |
| IO12 | VSYNC | 垂直同步 |
| IO11 | HSYNC | 水平同步 |
| 空 | DB0 | 数据线0 |
| IO10 | DB1 | 数据线1 B1 |
| IO9 | DB2 | 数据线2 B2 |
| IO8 | DB3 | 数据线3 B3 |
| IO7 | DB4 | 数据线4 B4 |

2 软件编程
开发环境基于VScode + ESP-IDF。关于RGB屏幕显示原理，这里不细说，只讲编程，感兴趣的同学可以自行查阅。
注：关于怎么在Vscode里面搭建ESP-IDF的开环环境，这里不具体说了，网上教程很多，不懂的同学请先自行搭建好环境。
2.1 新建工程
打开ESP-IDF，点击Show example。
选择rgb_panel例程作为我们的工程的基础模版。保存至本地，会得到一个工程模板，如下图：
注：esp32s3具备rgb接口，其他像esp32和esp32s2是没有的。
打开配置列表，配置时钟、FLASH和PSRAM等参数。
我的配置如下（仅供参考）：
初步编译一下。
注：因为这个模板默认把lvgl库加进来了，因此在编译的时候会自动下载lvgl组件并参与编译。如果不需要使用lvgl的话可以在idf_component.yml文件里面把lvgl/lvgl: "~8.3.0"删掉，这样就不会把lvgl加入进来，同时，还要把main里面所有跟lvgl相关的代码删掉，才能编译通过。
编译如果通过后，那工程的建立就没问题了。
2.2 编写ST7701S驱动程序
在工程main文件夹目录下新建st7701s.c和st7701s.h文件，并且在CMakeLists.txt文件加入"st7701s.c"，如下：添加st7701s.c之前：
idf_component_register(SRCS "rgb_lcd_example_main.c" "lvgl_demo_ui.c" INCLUDE_DIRS ".")添加st7701s.c之后：
idf_component_register(SRCS "rgb_lcd_example_main.c" "lvgl_demo_ui.c" "st7701s.c" INCLUDE_DIRS ".")文件目录如下：
然后编写ST7701S驱
动程序，示例代码如下：st7701s.c：
#include "st7701s.h"#define SPI_WriteComm(cmd) st7701s_write_cmd(st7701s_handle, cmd)#define SPI_WriteData(data) st7701s_write_data(st7701s_handle, data)#define Delay(ms) vTaskDelay(ms / portTICK_PERIOD_MS)void ioexpander_init(){};void ioexpander_write_cmd(){};void ioexpander_write_data(){};/** * @brief 新建st7701s对象 * @param sda sda引脚 * @param scl scl引脚 * @param cs cs引脚 * @param channel_select SPI, I2C通道选择 * @param method_select 可以选择SPI_METHOD,IOEXPANDER_METHOD * @note channel_select可选SPI控制器, SPI3_HOST OR SPI4_HOST in ESP32S3 * @note channel_select可选I2C控制器*/vernon_st7701s_handle st7701s_new_object(int sda, int scl, int cs, char channel_select, char method_select){ // if you use `malloc()`, please set 0 in the area to be assigned. vernon_st7701s_handle vernon_st7701s_handle = heap_caps_calloc(1, sizeof(vernon_st7701s), MALLOC_CAP_DEFAULT); vernon_st7701s_handle->method_select = method_select; if(method_select) { vernon_st7701s_handle->spi_io_config_t.miso_io_num = -1; vernon_st7701s_handle->spi_io_config_t.mosi_io_num = sda; vernon_st7701s_handle->spi_io_config_t.sclk_io_num = scl; vernon_st7701s_handle->spi_io_config_t.quadwp_io_num = -1; vernon_st7701s_handle->spi_io_config_t.quadhd_io_num = -1; // 默认值，启用DMA应设置为0 vernon_st7701s_handle->spi_io_config_t.max_transfer_sz = SOC_SPI_MAXIMUM_BUFFER_SIZE; // 不使用DMA最后赋值0 ESP_ERROR_CHECK(spi_bus_initialize(channel_select, &(vernon_st7701s_handle->spi_io_config_t), 0)); vernon_st7701s_handle->st7701s_protocol_config_t.command_bits = 1; vernon_st7701s_handle->st7701s_protocol_config_t.address_bits = 8; vernon_st7701s_handle->st7701s_protocol_config_t.clock_speed_hz = 40000000; /** * < 时钟极性以及时钟相位设置(CPOL, CPHA): - 0: (0, 0) - 1: (0, 1) - 2: (1, 0) - 3: (1, 1) **/ vernon_st7701s_handle->st7701s_protocol_config_t.mode = 0; vernon_st7701s_handle->st7701s_protocol_config_t.spics_io_num = cs; vernon_st7701s_handle->st7701s_protocol_config_t.queue_size = 1; ESP_ERROR_CHECK(spi_bus_add_device(channel_select, &(vernon_st7701s_handle->st7701s_protocol_config_t), &(vernon_st7701s_handle->spi_device))); return vernon_st7701s_handle; } else { ioexpander_init(); } return NULL;}/** * @brief 屏幕初始化 * @param st7701s_handle 类实例指针 * @param type 选择初始化类型 [1~x] * @note 以下类型来自不同地方，对应命令功能未知*/void st7701s_screen_init(vernon_st7701s_handle st7701s_handle, unsigned char type){ if (type == 1) {//从商家提供的资料复制 SPI_WriteComm(0x11); //sleep out í?3??ˉ???￡ê?

注：如果在工程中加入了新文件，需要先清除原来的编译文件，然后再重新编译，否则会报错。
编译并烧录。
运行结果：屏幕依次显示红绿蓝三种颜色。
至此，ST7701S驱动的RGB成功点亮。
结束语
好了，关于如何使用ESP32S3驱动RGB屏就讲到这里，有什么问题欢迎评论区留言。
