Hi all,

  My request is simply, has anyone been successful in controlling two steppers simply using only a Netduino Plus 2 + Adafruit Motor Shield V2 for Arduino?  I have read many (many) posts relating to the original shield and have reviewed all the code samples I can find but feel I may be missing something..   There have been comments that the shift register was too slow and so people went to alternative controllers.  With the on-board PWM chip in V2 this issue should have been aleviated but I have not found any references to people successfully using the shield as a standalone solution for steppers.  I particularly wanted to tap into the stackable feature as I would like to control up to six steppers..  Anyone had success here?

 If not, should I switch to arduino directly or is there a "simple" alternative that would allow me to control six steppers from a single netduino without overtaxing the processor?  

Many thanks in advance,

  David.

I'd also like this information; I have a Switec stepper running directly from four digital ports on my N+2, but I'd really like to use the I2C control of the Adafruit MotorShield v2.

Or not; it might be easier (and a whole lot cheaper) for me to just connect the Switec to a MCP23008.

I'm going to try to bring this thread up to the front, as I have the same question as David. I have also reviewed several different code samples for the original, and have not found a single usable one for v2.

I have written a stepper driver that supports the Adafruit V2 shield. To get anything like acceptable performance you will need to use a Netduino 2 or Plus 2 (the acceleration computations are quite CPU intensive so you need the beefier CPU of the Plus family).

 

I haven't tried stacking the shields but the code is designed to allow this. There are examples in the source repository - https://bitbucket.or...mf.motorcontrol
