Hi guys
Can any one provide me how to use queue inside UART ISR receive interrupt....
I have tried it using some web search but I couldn't achieve it can any one provide me the working example. below, I have attached my code and the image where my code got struck any one help me to find out the solution to my problem Iam using keil ide with FreeRTOS and stm32f429igt6 controller
xQueueHandle xQueue;
void USART_Configuration(void);
uint8_t uart_getchar(void);

ch = USART1->DR;
rxbuf1[rxptrh1++] = ch;
}
if (USART_GetITStatus(USART1, USART_IT_TXE)) {
if (txlen1) {
txlen1--;
USART1->DR = *txptr1++;
}
if (!txlen1) {
USART_ITConfig(USART1, USART_IT_TXE, DISABLE);
}
}
// taskYIELD();
}
void USART6_IRQHandler(void)
{
uint8_t ch;
portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE;
if (USART_GetITStatus(USART6, USART_IT_RXNE)) {
ch = USART_ReceiveData(USART6);
rxbuf2[rxptrh2++] = ch;
if(ch == '\n')
{
xTaskResumeFromISR(receiver_task);
}
}

if (txlen2) {
txlen2--;
USART6->DR = *txptr2++;
}
if (!txlen2) {

}
}
taskYIELD();
}
