Hello Every One!!
I am Using NUCLEO G0B1RE Board, facing Issue with CAN Receive Function I am using MICROCHIP CAN BUS ANALYSER and NUCLEO BOARD for CAN Communication
void CAN_Recieve(void){
while( (HAL_FDCAN_GetRxFifoFillLevel(&hfdcan1,FDCAN_RX_FIFO0) < 1 ) )
{
}
if(HAL_FDCAN_GetRxMessage(&hfdcan1,FDCAN_RX_FIFO0, &RxHeader ,RxData) != HAL_OK)
{
Error_Handler();
}
}
and also in my main function after all the HAL inits for my project
while(1)
{
CAN_Recieve();
ADC_Calculation();
delay_ms(1000); //1sec
PWM_Control();
}
let me explain what i have observed
for the first time when i send data from CANALYSER to Nucleo Board it receives Identifier and Data sucessfully, If i dont send the CAN message from CANALYSER for the send time the MCU is hang in the While Loop ,its not executing ADC calculation and PWM_Control functions in my main function
this is the API
while( (HAL_FDCAN_GetRxFifoFillLevel(&hfdcan1,FDCAN_RX_FIFO0) < 1 ) )
{
}
unless until I send another CAN message from CANALYSER it reads sucessfully.
I want to resume my Main Function even if send the CAN message from CANALYSER or not it should execute my Main function while Loop
please suggest me
Regards,
Karthik
