50黑币
stc12c5a想要在串口1接收到的内容后加回车换行符号后由串口2发送出去却实现不了，有大佬能帮忙看看修改一下吗？初始学徒比较菜
- #include<stc12c5a.h>

- void InitUART(void)
- {
- TMOD = 0x20;

- }
- void UART_1SendOneByte(unsigned char c)
- {
- SBUF = c;
- while(!TI);
- TI = 0;
- }
- void UART_2SendOneByte(unsigned char c)
- {
- RW=1;
- S2BUF=c;
- while(!(S2CON&S2TI));
