Uint8_t buffer [6].

Was going to do the modbus crc16 inspection, but every time when the buffer [0] ~ buffer [5] by cyclic repeating hexadecimal 0 x3f, serial debugging assistant always appear when I thought didn't exceed 0 xba uint8_t (0 ~ 255), then go to step to send, found that a single to send data when the results are normal, wrong feeling is at this point in the 0 xba,
This is to send a single character function definition:
Void COM_Sendchar uint8_t (ch)
{
USART_SendData (USART1, ch);
While (USART_GetFlagStatus (USART1, USART_FLAG_TC)==RESET);
}
No no bosses to solve the...

CodePudding user response:

USART_FLAG_TC USART_FLAG_TXE try instead

CodePudding user response:

while (! (USART1 - & gt; The SR & amp; USART_FLAG_TXE));

CodePudding user response:

Send out, whether to send the correct

CodePudding user response:

Should be a sign of your query is wrong, look at the corresponding series of library function or routine
