Re: Wide Field of View Distance Sensor

We do not specifically have distance sensors with a wide field of view. The idea behind narrow field of view distance sensors is to keep the sensing area well defined. As you widen the field of view of a single simple distance sensor, it becomes less clear if the nearest object in that field of view...

Re: Latency of Vint and Motor Controllers

It looks like your are using asynchronous function calls (BeginSetTargetPosition), which will queue up if you are calling them faster than they can be dealt with. Simple solutions could be to either use synchronous calls (myMotor.TargetPosition = x), or ensure you are limiting asynchronous calls to ...

Re: Correct Sensor Type for MOT2002_0 ?

A sensor type for MOT2002 has been added to the latest release of the Phidget22 library that will automatically filter incoming data and provide a 1 if there is motion or 0 if there is not. It is actually 3 sensor types (MOT2002_LOW, MED and HIGH), corresponding to low, medium and high sensitivity. ...

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...
