Write an RS485 communication program

I can give you an example of a simple RS485 communication program: #include "stdio.h" #include "RS485.h"

//Initialize RS485 RS485_Init();

// Main loop while (1) { // Read RS485 data int data = RS485_Read();

// 如果收到数据，则发送响应 
if (data) 
{ 
    RS485_Write(data); 
}

}
