hi, i am using STM32F746G-Disco in that i have receiving a 16 byte of data from other device,which can be get at interrupt . problem: i have created two threads for GUI and Uart Thread, in that uart thread i have i amcontinuously polling for uart data has receivedcompletely. Is there is anypossibility for resume task from whenever complete packet received from interrupt given below. i have tried below code it was hangs some where can any one help me this issue regards rajesh i have two threads 1. GUI and uart thread /*
uart thread that resumes from interrupt when data buffer fills in uart RX.
*/

UartThread(

}
}
else
{
if
(HAL_UART_Receive_IT(&UartHandle, (uint8_t *) aRxBuffer, 16) != HAL_OK)
{
}
else
{
vTaskSuspend(NULL);
taskState = TRUE;
}
