I don't understand interrupt declaration in FreeRtos.
In the Pic32 demo for example :
interupt prototype handler is declare with ipl set to 1 :
void __attribute__( (interrupt(ipl1), vector(_UART2_VECTOR))) vU2InterruptWrapper( void );
But Uart2 interrupt priority is set to 2 (as configKERNEL_INTERRUPT_PRIORITY is set to 1) :
ConfigIntUART2( ( configKERNEL_INTERRUPT_PRIORITY + 1 ) | UART_INT_SUB_PR0 | UART_TX_INT_EN | UART_RX_INT_EN );

So, what is the good setting ?

Thanks for your help.

I think this is really a question for Microchip as they provide both the compiler and the library - and both seem to provide a way of setting the priority. I asked the question when writing the port too.

I think the __attribute__ set priority level must only be used when you are not making library calls.

In this case, as far as I know/recall, the priority passed to the ConfigIntUART2() library function will be the one used at run time.

Regards.
