STM32F429I-DISCOVERY board

Birru Mahendar

Hi,

How use pushbutton as an external interrupt in Keil-RTX RTOS system.

I created threads for timer, Display and USB_HOST with reference of apnt268.pdf for stm32f429-discovery.

"http://www.keil.com/appnotes/docs/apnt_268.asp"

I'm now unable use button based on ISR.

Please help me.

Thanks

    So why are you unable to use a push-button?

    The interrupt system on the processor will not magically stop working just because you use an RTOS. You still configure the hardware the same. If you want the ISR to cooperate with the OS, you can then have the ISR generate an event, or maybe send something on a mailbox.
