电源

`

一、评估板使用说明

1. 功能

序号	功能	描述
1	MCU	MSP430F149
2	串口	控制esp8266交换数据
3	I/O	5路I/O
4	LED	工作指示灯
5	按键	复位按键
6	电源	5V电源输入

注：可实现的功能

a.可以显示预先存入屏幕内的图片广告信息

b.可通过手机app通过wifi切换图片

2. 需使用的工具

a．硬件：MSP430F149最小系统，ESP8266模块。

b. 软件： IAR。

c．原理图：详见“硬件原理图”文件夹。

d．程序： 430程序在“MSP430F149程序”文件夹。

二、评估板硬件和软件部分详细介绍

1.硬件部分
（1）硬件接口定义

功能	对应MSP430F149的IO
TXD(屏端子显示)	P34
RXD(屏端子显示)	P35
Esp8266串口	P36->RXT，P37->TXD

（2）硬件原理图

2. 软件程序
（1）界面设置在“DWIN_SET”文件夹中。STM32程序在“MSP430F149程序”文件夹中。操作过程：将app工程文件夹下的apk文件安装到安卓手机；将手机wifi连接上ESP8266的热点“电子便签”。
