在串口调试软件里，发送的数据单片机不能接收到，但能接收到单片机的数据。
程序如下：- #include "stm8s.h"
- #include "stm8s_uart3.h"
- #include "stm8s_clk.h"
- void CLK_Config(void)
- {
- CLK_DeInit();
- //CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV2);//change the default value DIV8 into DIV2
- }
- void UART3_Config(void)
- {
- UART3_DeInit();
- UART3_Init((u32)19200,UART3_WORDLENGTH_8D,UART3_STOPBITS_1,UART3_PARITY_NO,UART3_MODE_TXRX_ENABLE);
- }
- int delay(u16 time)
- {
- for(time;time>0;time--);
- }
- main()
- {
- static u8 data;
- //data=0X03;
-
- CLK_Config();
- UART3_Config();
-
- while (1)
- {
- data=UART3_ReceiveData8();
- delay(1000);
-
- //data=1;
-
- UART3_SendData8(data);
- }
-
- }
