Tool/software:
Hi support,
I am facing an issue while reading RXDATA UART0 in MSPM0G3507 controller. Below is my code.
void UART0_DIS_INST_IRQHandler(void)
{
uint8_t byteReceived = 0x00 ;
switch (DL_UART_Main_getPendingInterrupt(UART0_DIS_INST))
{
case DL_UART_MAIN_IIDX_EOT_DONE:
usart0_all_data_transmitted = true; // All data is transmitted
break;
case DL_UART_MAIN_IIDX_TX:
usart0_data_transmitted = true; // Fist phase transmiited
break;
case DL_UART_MAIN_IIDX_RX:
usart0ReceiveInProgress = true ;
while(!(DL_UART_isRXFIFOEmpty(UART0_DIS_INST))) // check if any byte in available to read
{
DL_GPIO_toggletPins(GPIOA_PORT, GPIOA_BYPASS_ON_LED_PIN ) ; //
usart0_rxData[usart0_rxCounter] = DL_UART_receiveData(UART0_DIS_INST) ;
if(usart0_rxData[0] == 0x01)
{
DL_GPIO_setPins(GPIOA_PORT, GPIOA_FAULT_LED_PIN ) ; // Enable max 485 for transmission
}
usart0_rxCounter++ ;
}
break;
default:
break;
}
In interrupt, i am reading the receiving data after checking FIFO status. I am not getting the actual received data. My receive FIFO interrupt is enable >= 2 level. GPIOA_BYPASS_ON_LED_PIN toggle on every byte try to read.
But GPIO_FAULT_LED_PIN never set. The receiving data have first byte is 0x01.
I believe that " DL_UART_receiveData(UART0_DIS_INST) ;" have some issue. Ant suggestion is welcome.
