'Scheduler' does not name a type error for nRF5240 with Arduino Core #132

Closed viggi1000 closed 2 years ago

viggi1000 commented 2 years ago

Hi,

I have been receiving type error while running any of the examples with the nRF5240 controller running the arduino core. While this library states that it has been tested with nRF52832 controller, I am not sure if this error is due to the different model number?

Here is the compile error from arduino:

Are you using Arduino IDE or PlatformIO? Please send your source - I can't help you without it. You can DM me to arkhipenko@hotmail.com

0x657373656C6C commented 2 years ago

I can confirm the same. It occurs with the basic examples in the examples folder so no special source code is required.

I am using PlatformIO.

arkhipenko commented 2 years ago

I just changed example #27 to run with nRF52840-DK and it compiled without errors. That is why I need to see your Platform IO project to be able to tell where the issue is. Scheduler_example27_PlatformIO.zip

0x657373656C6C commented 2 years ago

Same source as your .zip, different target board but nothing different in platformio.ini that would make a difference.

However, digging into the matter it seems that the 'Scheduler' variable of TaskScheduler conflicts with the Scheduler variable of SchedulerRTOS from FreeRTOS given that this lies beneath the surface of this platform.

Maybe that helps?

arkhipenko commented 2 years ago

The difference is that I don't get the error and I have used TS with FreeRTOS previously without conflicts... I would appreciate if you send the versions of your PlatformIO components and a zipped project that fails. arkhipenko@hotmail.com

0x657373656C6C commented 2 years ago

No, sorry, this is the best I can do. My project is extremely sensitive and I have moved off this scheduler due to time constraints.

arkhipenko commented 2 years ago

OK. Sorry about that. I cannot fix what I cannot reproduce. Good luck with your project!

0x657373656C6C commented 2 years ago

Right...here's the real culprit for what it's worth:

https://www.arduino.cc/en/Reference/Scheduler

This is enabled/compiled so not sure how to turn it off. However, it seems a localized problem.

arkhipenko commented 2 years ago

It's not RTOS. It's a separate scheduler that should not be used with TS. Of course there is a conflict.
