I'm trying to tick a gpio port on the shield base as fast as possible, but its doesnt seem to get up to the speeds I need. I really need it to be comparable with an arduino in speed.

 

I remember seeing this post about the netduino and native code, but is it possible to run native code on the shield base? 

 

On top of that, I have other modules that I would want to operate from the go, so the go main board would have to send the command to tick (under .Net MF), to the shield base (which is running native code)

 

Is this even possible?

not very fast. but you can use pwm, wich can be faster than arduino

I was actually messing around with that as your reply came in, and it seems to be working.

 

Do you know where I could find a layout the she shield base's PWM's? 

 

There was a lot of trial and error in trying to figure out where PWM_0 was (it was D5)

Heres the problem i'm having: I need to send ticks to an EasyDriver board to power a servo, and I can't seem to flip a gpio fast enough.

 

If I use PWM I can't be precise in my movements. I have been able to regulate the speed, but thats about it.

 

Any Ideas?

I stack with the same problem, solution is to develop own module, which is look like not going to be soon, may be loooooooooong expected bus 1.5 will help, but hope is little
