Apr 21, 2017 · Maybe ignoring the sonar sensor if you're acting on one or more of the other sensors will do what you want. One way to do it is to put a condition in your code that looks at the readings from all 4 ground sensors before deciding whether to read the sonar sensor.

Dec 30, 2016 · How do I change interrupt priority of serial driver so that it is higher priority than ethernet interrupt? 1 Initializes the UART with high priority receive interrupt in PIC18LF6722

How Priority Changing Code works? At the start, Task1 being the highest priority run first and enters the running state. After that, it prints out strings before raising the priority of Task2 to above its own priority.

Jan 28, 2016 · Interrupt sources can be assigned a priority, and you can set which priority of interrupt the system will accept. You can say, in effect, "continue to allow the timer tick interrupt, but disable all communications interrupts."

May 11, 2011 · The program could include just two functions, one (lets call it "A") with higher priority than the other. A has to perform a task (e.g. multiplication) after every arbitrary time period (e.g. 1ms). At all other times, the other function ("B") can perform whatever it needs to do.

Add FreeRTOS library in Arduino IDE; How to use FreeRTOS with Arduino IDE; Writing your first FreeRTOS based Arduino sketch; For demonstration, we will create four tasks and assign Arduino’s resources to each task for a specific time and also assign priority to each task.

Feb 25, 2014 · The loop function has priority -128 compared to ThreadHandler threads. How to use. Threads can be created via c++ inheritance. class MyThread : public Thread { public: MyThread() : Thread(priority, period, offset){} virtual ~MyThread(){} virtual void run() { //code to run } }; MyThread* threadObj = new MyThread();

This page goes beyond just removing delays, that was covered in How to code Timers and Delays in Arduino (instructable), and covers the other things you need to do for multi-tasking Arduino without going to an RTOS, such as avoiding Arduino …

Aug 25, 2023 · Using a task handle, your Arduino project points to a block of code (a function) you want executed on a specific core then assigns that code to the specified core. Note: I've not studied the code, that's just my simple layman's view of how this works.

Jan 13, 2023 · With the support of FreeRTOS, it’s possible to prioritize embedded tasks so they’re executed within strict deadlines. In this project, we’ll upload FreeRTOS on Arduino UNO to learn how it schedules embedded tasks. In this case, it will be to light up LEDs.
