SES 2.6寸墨水屏驱动程序

本文将介绍如何使用Ses2.6寸的墨水屏驱动显示三色内容。

墨水屏是博主在淘宝上捡垃圾购买的便宜拆机货点亮的效果还不错。

价格便宜又实惠适合个人DIY和学习使用

下面将介绍如何使用Arduino代码进行驱动程序

1. 硬件环境

以 ESP32C3开发版 （合宙）

驱动板是博主自己DIY制作的

下面是使用Vscode进行构建的代码

2. 驱动代码

使用微雪示例官方驱动 ： https://www.waveshare.net/wiki/E-Paper_ESP32_Driver_Board

选择驱动包是2.13寸 文件代码： EPD_2IN13BC

不过要修改代码内的尺寸为下面的

152 x 296

#ifndef __EPD_2IN13BC_H_
#define __EPD_2IN13BC_H_

#include "DEV_Config.h"

// Display resolution
#define EPD_2IN13BC_WIDTH       152
#define EPD_2IN13BC_HEIGHT      296

void EPD_2IN13BC_Init(void);
void EPD_2IN13BC_Clear(void);
void EPD_2IN13BC_Display(const UBYTE *blackimage, const UBYTE *ryimage);
void EPD_2IN13BC_Sleep(void);

#endif
