Re: how can I detect limit switch using 1067 ? by currentCha

You are correct, the 1067 on its own cannot support limit switches or an encoder because it does not have digital inputs or an encoder input, respectively. The reason we removed the digital inputs is because our board design philosophy is shifting towards modularity, rather than trying to include ev...

Re: Connect multiple Phidget on a USB hub ?

Yes, it is possible to have multiple motor controllers on the same USB hub, as long as they are both provided with sufficient power. You will need to open two separate objects in software- one for each motor controller.

Re: C prog on SimpleServo,sometimes servo motor spins endles

Are you sure you're setting the min and max pulse width properly with setServoParameters? If the servo is running even when it's not given a target position, that means that the zero position is being interpreted by the servo as something that's not zero. Have a look at this page for more information.

Re: Multiple tag reading with help of two readers

The problem with trying to detect multiple RFID tags is that there's no way to select which tag is going to respond if you just throw them into a box. When the reader's antenna activates, any RFID tag within range will activate and broadcast its tag data. Whichever one is picked up by the RFID reade...

Re: setCurrentLimit triggers Position changed handler, not c

No, you don't need to call getCurrent if you already know what you want the current limit to be. Play around with the current limit, velocity limit, and acceleration in testing to determine which numbers work well for you, and then set those properties when your program begins.

Re: Connect Current Tranducer direct to interface board 2/2/

Yes, the 3513_0 requires 12V power, so you'll either need the 1144 to step the 5V supply up to 12V, or you'll need to provide an external 12V supply and connect it as shown in this diagram.

Re: connect 2 3105_0 sensor to the same Voltage Divider

The 3105 is kind of small to use with a DDR pad, since it's only 1.5x1.5 inches. If you stepped on the edge or corner of the arrow it might not trigger, unless you built the pad in such a way that the entire arrow is resting on the 1.5x1.5" area. I would look into using load cells instead, and ...

Re: 1040_0 - PhidgetGPS, removing magnetic part from antenna

The magnet only exists to attach the antenna to metal surfaces, so theoretically you should be able to use it without the magnet. I've never tried to take one apart, so I don't know how difficult it would be to remove without damaging the antenna. The PhidgetGPS should work with any GPS antenna with...

Re: Recommended way to continually calculate acceleration: 1

By default the data rate is set to 8ms, so you'll get a new data event every 8ms even if the acceleration didn't change at all. You can change the data rate to a larger time interval (any multiple of 4 up to a maximum of 1000ms) or you can create a function in your data event handler that only recor...

Re: record and repeat Robotic arm (arduino vs raspberry pi?)

The only Phidgets motor controller that can run bipolar stepper motors is the 1067 . It's designed to be able to handle our largest stepper motors, and it can only control 1 motor, so it may not be ideal for your situation with five smaller motors. Most Arduino-compatible motor boards or shields usu...
