Arduino系列：T5UIC1串口彩屏与MEGA2560交互，实现常用功能（附例程）

开发板

一、开发板使用说明
1. 功能

序号	功能	描述
1	MCU	ATMEGA2560-16AU
2	I/O	1路I/O
		IO检测：检测闸刀的导通还是断开
3	ADC	3路AD
		CH1：电压采集(模拟数据采集)
		CH2：电流采集(模拟数据采集)
		Temp：温度采集(模拟数据采集)
4	LED	工作指示灯
5	按键	复位按键
6	电源	USB 5V电源输入

注：实现的功能：
a．上电后发送指令屏的握手指令给T5UIC1屏，T5UIC1屏收到指令后回返回应答信息，当MCU没有收到应答信息时，T5UIC1屏显示开机界面同时MCU的LED灯为常亮。
b. 当MCU收到T5UIC1屏的握手回应后，MCU通过页面转换指令进入“初始化系统”页面，显示倒计时5秒钟。
c. 当倒计时页面到达5秒后便进入主界面，此时MCU LED工作指示灯以200ms间隔闪烁以示工作正常状态，主界面显示当前MCU采集ADC通道的数据值，同时显示闸刀开关的状态。
d. MCU每3秒采用一次AD数据并更新到T5UIC1屏上。

2. 需使用的工具
a．硬件：arduino-mega2560_R3学习板（MCU为atmega2560，串口TTL电平）。
b．软件：Arduino-IDE。
c．原理图：详见“硬件原理图”文件夹。
d．程序：T5UIC1屏工程配置文件在“T5UIC1屏配置文件与图片”文件夹中，通过SD卡下载DWIN_SET导入屏中即可。 mega2560_R3程序在“mega2560 源码”文件夹。
