Particle threads tutorial Threads allow concurrent execution of multiple bits of code. They’re popular in desktop operating systems like Windows and in languages like Java. Threads have limited support in the Particle platform, but exist. Though the semantics are a bit different, you might use thre…

Great tutorial, thank you very much. I have a some questions: I was not aware that the main loop thread on the Electron is only called 100 times per second, why is this? Is this also true for SYSTEM_THREAD(ENABLED) With SYSTEM_THREAD(ENABLED) I think there is already a queue on the application t…

The Electron loop() only runs 100 times per second vs. 1000 on the Photon when you are not using SYSTEM_THREAD(ENABLED). However, when you have SYSTEM_THREAD(ENABLED), it runs really fast, using all excess CPU, at least in 0.7.0 on the Electron. I’d probably just use the macros like APPLICATION_TH…

First of all, thanks for this, some great stuff in one place. One note that might be useful to some folks - one can declare the thread before initializing it, giving an opportunity to set flags, initialize variables and queues in setup() or anywhere else as long as you do it before you initialize t…

delay() on the Electron just called vTaskDelay so they should be equally efficient. On the Photon it calls into WICED, but it probably works the same. The main difference is that os_thread_delay_until takes care of the math to keep the period constant. The tip to delay start of the thread until se…

The tip to delay start of the thread until setup is good. However, it’s also currently broken in 0.7.0 so you may not want to use it right now. Ah, well that explains why my firmware hard faults on 0.7.0 (at least partly)! I didn't bother debugging it, just stuck with 0.6.4. I have a feeling yo…

Hello! This is a fantastic tutorial. I was reading up on priorities in the FreeRTOS documentation and was wondering what the OS_THREAD_PRIORITY_DEFAULT is and does.

I’m very new to Threads so bear with me for this question on fundamentals. In the first block of code, under How fast does a thread run? with the incrementing a counter example, could you explain the order of execution of the setup, loop, and threadFunction? I’m assuming first, setup runs. Then, doe…

[image] shubhajagannatha: order of execution of the setup, loop, and threadFunction? I’m assuming first, setup runs. Then, does the thread function run after every time the loop runs? Do they go back and forth in running? Threads and functions are different concepts. When you take setup() an…

[image] rickkas7: void threadFunction(void *param) { while(true) { counter++; // Delay so we're called every 10 milliseconds (100 times per second) os_thread_delay_until(&lastThreadTime, 10); } // You must not return from the thread function } Is there a way to run the thread functi…

No, that’s not how the threads work. If you want one thread for all timers, run sequentially, use the software timers . There will only be one thread, and it will call each timer in sequence. The downside is that a mis-behaved timer can stop all the others from executing. The flip side is one threa…
