Hi everyone,

Is it possible to control 3 stepper motors seperately via using the drivers with LPC1768? I see only 2xI2C connections.

Driving 3 steppermotors should generally not be a problem even at maximum speeds of the motors, but it depends on what else the mbed has to do at the same time. The number of pins you need depends on how you drive the steppermotor (either directly by mbed pins and a simple transistor driver or by a dedicated stepperdriver IC). A search for steppermotor on the mbed site returns many hits that should help you get started: http://mbed.org/search/?type=&q=steppermotor

Thank you a lot. I'm checking the link btw. So, I will use a sensor as input data, and stepperdriver IC's as output. And luckly, I don't need to control motor speeds, (fullspeed)work and stop will be pretty much enough for me .

Ps: I might add another sensor to it, depending on the clearance of project. As soon as everything is ready, i would like to share it.

thanks.
