Look at the Atmel data sheet, there seems to be quite a sophisticated Timer/Counter block in the ARM7. However I can't find any reference to it anywhere in the .net MF or Netduino SDK. Of course there is System.Threading.Timer but that is limited to 1ms resolution and I'm not sure how 'deterministic' it is.

 

I would like to run a timer faster than 1ms intervals and ideally have an interrupt handler that runs every time it elapses.

 

It this straightforward to do within the NetMF/Netduino framework? Any pointers?

 

Thanks,

Well, there are no classes for direct timer access in the current version of .NET Micro Framework, mainly due to the fact that the managed (C#) code is interpreted and running considerably slowly than native (C++) code. IIRC simple pin toggling loop on Netduino gen. 1 can achieve ~10 kHz. Even if you were able to access the timers, you would not have much time to run managed code in the interrupt handler (if at all).

 

What do you want to do?
