Is it possible to implement a system timer interrupt version (rather than WDT) compatible with Arduino IDE? #108

Hello Phillip,

I find the 15 ms time slice is still too large to meet the requirement of something like robotic control. I noticed another task management library for TaskManagerIO on https://github.com/davetcc/TaskManagerIO, which supports microsecond-level scheduling and works with Arduino IDE. Is there a way to introduce timer 0,1 properly into freertos into Arduino IDE?

Best regards

I have many different options for timers using (Arduino) ATmega boards. They're all available here at avrfreertos.

You'll need to be aware that the Arduino IDE will fight you for resources (Timers etc), so you may have to redo configurations after the setup() function completes. All the Timers are supported on any of the standard Arduino hardware.

Down to about 1ms is the best timing option, imho.

Thank you for reply. I have checked the repository I mentioned above. It dose not use any timer at all but depend fully on the arduino loop. I will use the avrfreertos library instead.
