However, you can take a look to the freertos_i2c example which implements i2c interrupt and you can take as reference for&nbsp; task and interrupt synchronization.</P><P>&nbsp;</P><P>In addition, please have in mind that ISR has higher priority over tasks. Please check the following posts from a colleague as it may be useful for you.</P><P><A class="link-titled" href="https://mcuoneclipse.com/2016/08/14/arm-cortex-m-interrupts-and-freertos-part-1/" title="https://mcuoneclipse.com/2016/08/14/arm-cortex-m-interrupts-and-freertos-part-1/">ARM Cortex-M, Interrupts and FreeRTOS: Part 1 | MCU on Eclipse</A>&nbsp;</P><P><A class="link-titled" href="https://mcuoneclipse.com/2016/08/20/arm-cortex-m-interrupts-and-freertos-part-2/" title="https://mcuoneclipse.com/2016/08/20/arm-cortex-m-interrupts-and-freertos-part-2/">ARM Cortex-M, Interrupts and FreeRTOS: Part 2 | MCU on Eclipse</A>&nbsp;</P><P><A class="link-titled" href="https://mcuoneclipse.com/2016/08/28/arm-cortex-m-interrupts-and-freertos-part-3/" title="https://mcuoneclipse.com/2016/08/28/arm-cortex-m-interrupts-and-freertos-part-3/">ARM Cortex-M Interrupts and FreeRTOS: Part 3 | MCU on Eclipse</A>&nbsp;</P><P>&nbsp;</P><P>Best regards,</P><P>Felipe</P></BODY></HTML> Wed, 25 Sep 2019 16:37:13 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Wake-up-gpio-driver-with-interrupt-notificationfromISR-on/m-p/952174#M54770 FelipeGarcia 2019-09-25T16:37:13Z
