Re: BLDC motor isn't reading back the correct velocity

When using the BLDCMotor API, the the BLDC motor controller has an Acceleration parameter that will ramp the motor's Velocity (aka duty cycle) from the current Velocity to the TargetVelocity . After the acceleration period, we expect Velocity to match TargetVelocity . You will get the motor's curren...

Re: Humidity phidget works with hub but not SBC

Your previous post indicates you were using an HUM1001, but this post indicates HUM1000. I just want to clarify which sensor you are using, or if it is indeed both.

Re: Correct Sensor Type for MOT2002_0 ?

I will caution against using this sensor with the DigitalInput API, in that the voltage from the sensor can swing up or down, while the DigitalInput will only detect in one direction.

Re: BLDC motor isn't reading back the correct velocity

None of our motor controllers have PID velocity control built-in. Given the extremely coarse position feedback from the hall-effect sensors on BLDC motors, it is unlikely the DCC1100 ever will. There is not enough resolution to give a truly accurate measure of velocity built-in to the controller. Th...

Re: Correct Sensor Type for MOT2002_0 ?

As for the original question, it appears the MOT2002 sensor type does not currently exist, but likely should. We will look into it.

Re: Correct Sensor Type for MOT2002_0 ?

Opening the hub port as a VoltageInput will allow you to set your own limits on how sensitive your system is to detecting motion, by detecting if the sensor's voltage is outside of a given threshold. SATURATION errors occur because the signal from the analog sensor is too large to be accurately quan...

Re: VINT with continuos and 2700 degree servo

The continuous rotation servo likely translates a standard RC Servo PWM signal to a direction and velocity. To verify this for yourself, you can adjust the Position property of said servo to see how it affects the movement. For the 8 revolution servo, you can adjust the MinPosition and MaxPosition p...

Re: Is it possible to use this DAC to generate a 1kHz signal?

None of our devices currently support generating a custom high-frequency analog signal.

Some of our digital output devices have settable frequencies, such as the OUT1100, but I'm betting that's not likely what you are looking for.

Re: State persistence of DigitalOutputs through Network Server

It is true for Windows, and all other operating systems. "Bonjour for Windows" allows your computer to find Phigdets on remote networks without necessarily needing to specify an IP address or hostname. You need a program to actually open the Phidget if you want to keep its state. Hypotheti...

Re: State persistence of DigitalOutputs through Network Server

The idea of using a "remote" connection to keep Phidgets open after a program is closed is to use two programs. One to keep the Phidgets alive, and one to control them. The first program will open the Phidgets, and remain running indefinitely doing nothing else. The second program is the o...
