STM8 serial port receiving string problem-EEWORLD

Collect

Attached here is the receive interrupt source code

#ifdef _RAISONANCE_

void USART_RX_IRQHandler(void) interrupt 28

#endif

uint8_t cnt_USART;

#ifdef _IAR_SYSTEMS_

#pragma vector=30

__interrupt void USART_RX_IRQHandler(void)

#endif

{

/* In order to detect unexpected events during development,

it is recommended to set a breakpoint on the following instruction.

USART_ClearITPendingBit (); // Clear interrupt flag

if(!USART_GetFlagStatus (USART_FLAG_RXNE)) //Wait for reception to complete

{

p_rxbuf[cnt_USART++] = USART_ReceiveData8(); //Receive data

if(cnt_USART == 0x0B)

cnt_USART = 0xFF;

}

// USART_RendCmd(p_rxbuf); //Receive 11 bytes serial port command

}

cnt_USART is a global variable. Since only 1 byte is received each time, the main program should perform an appropriate delay to wait for the data in the buffer to be read.

while(cnt_USART!=0xFF)

{

if(mark_1ms >100)

break;

}

Perform appropriate delay in the function to wait, mark_1ms here uses TIM2 for delay, and you can also perform empty function delay in the main function.
