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。$ ~; m3 M. n& K, [, D0 u# O$ Q6 |" n
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。
( [# q9 t' x5 ec. 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。# y+ c5 x& L" x; U' m
