esp8266虽然硬件资源比较少,但是用它驱动LCD并做一些简单的应用还是可以的。 本文介绍的软件开发基于Arduino,esp8266开发的方式有很多,对于功能较为简单的项目或者前期方案验证,用Arduino是最简单最直接的。 1 硬件介绍 本文的硬件配置如下: 1.1 模块介绍
LTDC全称 LCD-TFT Display Controller,LCD显示控制器,提供了RGB信号和控制信号来直接控制外部LCD显示屏。 为什么是直接控制呢? 一般TFT-LCD 屏幕中带有驱动IC,并集成有显存,其内部就在不断的将显存内容显示到LCD面板上,我们驱动这类屏幕时往往是直接去操作驱动IC,通过发送操作命令来设置显示模式,通过发送显示数据来修...
