FreeRTOS Binary Semaphore – Examples of Tasks Interrupt Synchronization using Arduino FreeRTOS Counting Semaphore Examples with Arduino FreeRTOS Mutex Tutorial with Arduino – Avoid Priority Inversion Arduino FreeRTOS Recursive Mutex to avoid Deadlocks FreeRTOS Interrupt Management Examples with Arduino...
In the last tutorial, we have seen how to useBinary Semaphore with FreeRTOS and Arduino. We have learned to synchronize software tasks and tasks with interrupt service routines using binary semaphore. In this tutorial, we will learn to use the counting semaphore of FreeRTOS and examples with Ar...

The lower the Interrupt Vector address, the higher the priority. The I/O memory space contains 64 addresses for CPU peripheral functions as Control Registers, SPI, and other I/O functions. The I/O Memory can be accessed directly, or as the Data Space locations following those of the ...
to specify that you want to use a Pin Change Interrupt type of interrupt on those pins that support both Pin Change and External Interrupts. Otherwise, the library will choose whatever interrupt type (External, or Pin Change) normally applies to that pin, with priority to External Interrupt. ...
