摘　　要：基于 RoyalTek REB-12R 接收机的 GPS 信号显示器,利用 MCU 处理 REB-12R 输出信号并在 LCD 显示。开机时 MCU 串口初始化使默认值格式符合 GPS,从 TXA 输出默认信号格式和输出信号格式。MCU 接收 GPS 的ASSIC 字符进入中断程序,然后判断数据起始位再送显示缓存。The output signal of REB-12R is processed and displayed on LCD through MCU in design of GPS signal displayer based on RoyalTek REB-12R. When PC began, MCU serial port was initialized to make default signal format corresponds with the signal outputted from the TXA port of the GPS receiver. The ASCII characters received by MCU from REB-12R was sent into the interrupt service program and started bit of data was judged and then inputted into the displaying buffers of LCD.
