we're kind of newbies with vvvv and arduino, after some projects just running motors over pwm + pins we're trying to get a stepper work by talking over IC2 protocol from vvvv to the stepper driver.
We're a bit confused with the sysex messages. What we don't get is how the proper sysex message send from v should look like and how a single command has to be sorted in the spread of possible commands then put as [Raw] to the 'FirmataBoard'. We've been looking for IC2 libraries, the right commands and examples but couldn't find something appropriate. We honestly also don't get the full concept how to introduce it into the v4-patch plus how into the firmata code as IC2 adress.
Anyone knows about tutorials here or maybe some exaples to learn?? Help!!
We've got a bipolar stepper motor on an adafruit motor shield, vvvv beta 50_35 x64
Thanks a lot!!
