we try to get a uniploar stepper moving on a Arduino Mega and a Motorshield (Laydyada).
If we connect everything and upload a stepper-test directly to the Arduino by using the arduino program everyting works fine. So the connection and the hardware seem to work fine.
Now we want to control the same thing by using vvvv.
The firmata doesnt work, we don´t know why. So we use the Basismata to send the sequence to Pin 3 and 11 (both PVM). We send a sequence like 101010101010…on one pin and the inverted value on the other pin. The LFO switches every 0.02 sec. But we don´t get any result.
Does anyone know where to find more informations about the sequences we have to send and how i can do microstepping etc. ??
Or does anyone have an idea of how to get the firmata working on the Arduino Mega/Uno ?
