RPIPicoFreeRTOSCourse

Course Repository for Udemy Course: FreeRTOS on Raspberry PI PICO

16 Examples of which 15 demonstrate FreeRTOS features on the Raspberry PI Pico or RP2040 board. One of which that focuses on the SDK multicore API functions.

2 Pico Setup

  • BlinkLEDExt: Blink an external LED on GPIO using a function approach.

4 Tasks

  • Blink Ext: Blink an external LED on GPIO 0, encapsulating the task within a Class.
  • MultiBlink: Blink multiple LEDs using different task priority
  • BlinkPriority: Use priority with tasks that create CPU workload
  • BlinkAssignment: Explore priority

5 Semaphore

  • SharedLED: Defined shared LED which will be used by two blink LED pair objects. Creating a contention scenario that requires semaphores.
  • LimitWorkers: Use count semaphore to limit the number of active tasks using a resource
  • AssignmentLimitWorkers: Explore counting semaphores in assignment
  • BlinkWorker: Create a scenario of workers that will blink out of sync
  • TaskNotification: Use task notification as two semaphores to synchronize the two tasks

6 Queue

  • CountLed: Display a binary value on four LEDs (0 to 15) that is being sent to the task via a queue
  • AssignmentQueue: Assignment question to use queues

7 MessageBuf

  • JsonCmds: Use of message buffer to send a JSON strong to a task. Decode the JSON and display the contained value on four LEDs
  • SerialCmds: Two Pico communicating together over UART to display the same value on four LEDs in sync

8 Multicore

  • sdKMulticore: Use both cores and send a random number from core 0 to core 1 using the SDK FIFO queue
  • FreeRTOSSMP: Use SMP to run tasks across both cores and some associated with single core
