#59924 Maximum port frequency ...

Posted by mikepo on 28 August 2014 - 05:17 PM

I think we can safely exclude 100MHz and 2GHz, but you probably already knew that :)

500kHz looks pretty unlikely too ...

 

Does this help (towards the end of the post, under: "Bit toggling"):

It's not talking about Netduino in particular but the .Net Micro Framwork in general. But some good insights ...

 

"So basically, with a 100 MHz processor, you can usually do around 20 ?s wide pulses using managed code (about 25 kHz)."

 

Another similar discussion on the TinyCLR forum:

"72 MHz sounds very fast.
But I was surprised that outputting an alternating 0 and 1 via .NET code was so slow!
I got only 10 kHz."

 

 

So I am guessing it would be less than 10kHz, if your code runs on the Netduino Go and communicates the command to toggle a pin to the shield base over the go!bus protocol ...
