PORTA availability

Posted by Robert Brock on April 16, 2009

My target is an ATMega323 and I am working on a simple example where I set/clear bits on PORTA from within a spawned task just to verify the task is running. The xTaskCreate call appears to work based on the return value, but PORTA does not get updated. If I move the PORTA manipulation outside of the task, it works fine. Do I need to do something specific to enable port manipulation from within a task?

Have you started the scheduler vTaskStartScheduler
after creation of tasks?

What a rookie mistake. Started the scheduler and everything began working. Thanks.
