VB串口自动检测为什么总是无效的端口号8002
你得注释, 越看头越大, unsigned char fifo_head=0; \\\/\\\/往fifo写入数据时的位置unsigned char fifo_tail=0; \\\/\\\/ 读出fifo时的位置unsigned char Rx1_pos=0; \\\/\\\/当前的接收位置unsigned char Rx1_num=0; \\\/\\\/数据长度unsigned char Frame_in=
能帮我写一个用C语言实现的串口通讯程序吗
供参考void MCU_Initialize(void){ SCON =0xDC; \\\/\\\/在11.0592MHz下，设置串行口波特率为9600，方式3,并允许接收 9为 SCON = 0x50; TCON = 0x00; TMOD |=0x21; \\\/\\\/定时器工作于方式2，自动装载方式 T0 16位定时器 TH1=0xFD; IP = 0X90; ES=1; ET0=1; \\\/\\\/TR1=1; EA=1;}\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/发送一个字节\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/*void putchar(unsigned char byte){ if(JO_check(byte)==1) TB8=0; else TB8=1; SBUF=byte; while(!TI) TI=0;} *\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/串口接受程序 与350通信\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/\\\/void RX() interrupt 4{ if(RI==1) { RI=0; C8051F350[CaiYangJiShu]=SBUF; if(RB8==JO_check(C8051F350[CaiYangJiShu])) { Ji_Ou_fail=0; \\\/\\\/奇偶效验失败 通知F350从新发送 } CaiYangJiShu++; if(CaiYangJiShu==8) { TR1=0; CS_350=1; CaiYangJiShu=0; \\\/\\\/ CAIYANG_over=0; \\\/\\\/完成一次采样标志 if(C8051F350[0]==0x55 && C8051F350[1]==0x55 && C8051F350[6]==0xAA && C8051F350[7]==0xAA&&Ji_Ou_fail==1) { CAIYANG_over=0; CaiYnagDat=0; CaiYnagDat<<=8; CaiYnagDat += C8051F350[5]; CaiYnagDat<<=8; CaiYnagDat += C8051F350[4]; CaiYnagDat<<=8; CaiYnagDat += C8051F350[3]; CaiYnagDat<<=8; CaiYnagDat += C8051F350[2]; } } }}这个程序是带奇偶校验的,可以在设置的时候去掉
我照着visual C++\\\/turbo C 串口通信编程实践写的 接受数据的程序 不能用 我有检查串口是没有问题的 求解
这个可以有啊，好多这种软件的，网上搜串口监视马上就出来的，只要改下通信协议，我这里有几个上位机，可以用哦
