SAM4 USART interrupt code example
Is there a sample code for using USARTx with interrupts in FreeRTOS ?
Thank you

Yes – there are numerous examples in the Atmel ASF (Atmel Software Framework). Look of “FreeRTOS Peripheral Control” examples in the ASF download (http://asf.atmel.com). See http://www.atmel.com/images/doc42049.pdf

I am sorry, but I have looked at that for a week now and nothing I do works.
My code is stuck repeating the same USART1_handler() over and over again.
I tried to follow the SYS_TICK interrupt as a model, but that did not work.
I would guess that I am not actually clearing the USART1 interrupt, but I just do not see why I can not do it.
As soon as I enable that interrupt, it starts and does not end.
If pasting the code here would help, I will. ( I know its frowned upon)
Thank you (again)

I don’t think the example uses USART1_handler() because it uses the DMA interrupts instead. I could be wrong though.
