    • The naked Attribute

    Posted by spflanze on 2016-02-17 00:38

    There is a description of how and why the "naked" attribute is used for ISRs on this page:
    http://www.freertos.org/implementation/a00013.html

    Should I be adding this for the Callbacks ST32CubeMX created for servicing the timers and A to D converters? I have included FREERTOS in the project.

    Should the "FromISR" versions of FREERTOS calls be used within callbacks?

    Hi,

    On Cortex-M based processors the "naked" attribute should not be used for ISRs; the processor itself does what is needed so that a normal function can be used as an interrupt handler. The prototype should be:
    Copy to clipboard
    void ''ISRname''_IRQHandler(void);


    Regarding the ISR code, yes, your ISR should only use FromISR versions of the FreeRTOS functions.
