Wake up gpio driver with interrupt (notificationfromISR) on freeRTOS

[satsok_n]

I am using the freeRtos examples of KW41Z sdk on MCUxpresso. Is there any example of awaking the gpio driver task from an interrupt?

Hello Kostas,

Unfortunately, there is no example exactly as you needed in the SDK. However, you can take a look to the freertos_i2c example which implements i2c interrupt and you can take as reference for  task and interrupt synchronization.

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.
