Arduino UNO + LabVIEW for Master/Slave Robotics

[d.gelman]

Hello,

I have purchased the UNO and using it as a hardware interface with LabVIEW as everyone here is doing.  My application is to retrieve 3 sets of quadrature encoder signals 3DOF and apply them to 3 DC motors - essentially a master/slave system.  Is the Arduino capable of doing such things?  Processing around 3KHz and RT.

Note that I have purchased DC motor shields for the Arduino.

The Uno can only do a single quadrature encoder.  To do three on a single board, you need the Mega2560.  Also, encoders require custom firmware.

Although, I think I remember something about using only a one interupt pin and one digital pin for a quadrature encoder but I don't know how reliable that is.  If you did get it working this way, you can get two encoders on an Uno and 6 on a Mega2560.
