DFRobot_0.96

简介

这是一款小巧精致的0.96英寸TFT彩屏，采用无边框PCB设计，体积小巧，并且拥有160*80高清分辨率16-bit（RGB565）色彩显示，显示效果极佳，可应用于可穿戴、移动设备、智能家居等产品中。
它支持DFRobot GDI显示接口，搭配支持GDI的主控时可以通过FPC线连接，即插即用，有效减少接线步骤。
它支持3.3V和5V，全屏的最大工作电流不超过15mA，并兼容多个主控：UNO、Leonardo、ESP32、ESP8266、FireBeetle M0等。

引脚说明

标号	名称	功能描述
1	VCC	电源正极
2	GND	电源负极
3	SCLK	时钟
4	MOSI	数据（主机发送从机接收）
6	CS	屏幕片选
7	RT	复位
8	DC	数据/命令
9	BL	背光。背光设定了默认值，用户不用连接背光引脚也可点亮；此外，连接背光引脚，输入高电平（1）是将背光亮度调到最大，输入低电平（0）是关闭背光

使用教程

该产品是Breakout模块，采用SPI通信方式，板载GDI接口，降低了接线的复杂程度，并且可以轻松地显示从SD卡中读取到的内容

注意：

1.GDI接口的使用需要与具有GDI接口的主控相匹配

2.建议使用Arduino1.8.10及以上版本

3.SD卡插槽接触不良，有可能会初始化失败，插拔后成功
