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:EDN USB学习板(MCU为STC89S52,串口TTL电平)。
b.软件:Keil C51 V9.00;stc-isp-15xx-v6.82.exe(烧录软件)。
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。 STC89S52程序在“STC89C52RC 源码”文件夹。
