ATmega 32 , Waking a task from an ISR

Posted by rtel on January 18, 2018

There are lots of different ways - queues, semaphores, event groups, stream buffers, message buffers can all be used to wake a task from an interrupt. As a starting point for you I would recommend looking at task notifications - as that is one of the most efficient ways. The first link gives an overview of task notifications, the second has a code snippet showing interrupt to task notifications.
