SPI - INTERRUPT - RTOS

Hi,

is it possible to throw an interrupt when there is activity on a SPI communication? I would like to do something like this :

SPI.attach(myInterrupt);

Is it then possible to use an RTOS and start a thread inside this interrupt?

thanks.

Do you mean SPI master or slave? Since an SPI master will only have activity when you tell it to have activity.

Thanks for your answer.

I wanted the MBED to be slave.

What I have is :

touchscreen (SPI) sensor (UART)

I want to use a RTOS. The touchscreen when touch should start a interruption. Also, the sensor send info once in a while. I want it to start an interruption each time info is send on UART.

The interruptions should start threads

That is the way I thought it has to be done....

thanks
