初学串口，串口发送有数据，但数据错误，按照例程编的，就是不知道哪里有问题，贴出来请教各位老师。
- #include "stm32f10x.h"
- void Delay(unsigned int x);
- void UART_Init(void);
- void UART2_PutChar(unsigned char ch);
- int main(void)
- {
- SystemInit();
- UART_Init();
- while(1)
- {
- Delay(6550);
- UART2_PutChar(0x26)；
- }
- void UART_Init(void)
- {
