使用了指纹模块，STM32 ，屏幕，加Modbus串口通信协议

屏幕使用UART4 ，modbus 通信和STM32
int main(void) { INIT_CPU(); T2_Init(); UART4_Init(); EA=1; // UART4_SendStr("hello",sizeof("hello")); WDT_ON();//打开开门狗
while(1) { WDT_RST();//喂狗 Process(); } }
void MainMachineHandle(void) { if(UartDataHandle) { uartHandle(Uart4_Rx,uart4_rx_count); CLR_UartMp3(); } }
bool uartHandle(u8 *Tdata,u8 len) { u16Wlen=0; u16CRC_1=0,BegAddr=0; u8 xdata RetData[Uart4_Rx_Maxlen+10]; u8 errnum=0;
CRC_1=CalcCrcAll(0xffff,Tdata,len-2); if(CRC_1!= ((Tdata[len-1])<<8 | (Tdata[len-2]))) returnfalse;
//这个为写指令 if(Tdata[0]==0&& Tdata[1]!=0x06) { returnfalse; } elseif(Tdata[0]!=DevAddr) //设备地址 { returnfalse; }
//这个为写指令 if(Tdata[1]!=0x03&& Tdata[1]!=0x06 && Tdata[1]!=0x10 ) { SendModbusAckErr(Tdata,1); returnfalse; }
Wlen=(Tdata[4]<<8|Tdata[5]); //长度 BegAddr=(Tdata[2]<<8|Tdata[3]); //开始地址
if(Tdata[1]==0x06)//写内存 { write_dgusii_vp(BegAddr,&Tdata[4],1); } elseif(Tdata[1]==0x10) { write_dgusii_vp(BegAddr,&Tdata[7],Wlen); }
//读操作响应 //[01][0x03][00][6B][00][02][CRC高][CRC低] if(Tdata[1]==0x03) { RetData[0]=Tdata[0]; RetData[1]=0x03; RetData[2]=Wlen*2; read_dgusii_vp(BegAddr,&RetData[3],Wlen); CRC_1=CalcCrcAll(0xFFFF,RetData,3+Wlen*2); RetData[Wlen*2+3]=CRC_1; RetData[Wlen*2+3+1]=CRC_1>>8; SendModbusAckOK(RetData,3+Wlen*2+2); } elseif(Tdata[1]==0x10) { memcpy(RetData,Tdata,6); CRC_1=CalcCrcAll(0xFFFF,(INT8U*)&RetData,6); RetData[6]=CRC_1; RetData[7]=CRC_1>>8; SendModbusAckOK(RetData,8); } elseif(Tdata[1]==0x06 && Tdata[0]) //当地址码为真，才应答 { memcpy(RetData,Tdata,8); SendModbusAckOK(RetData,8); }
returntrue; }
