SLIDE4: Quad Slide Potentiometer Input

The SLIDE4 peripheral lets you monitor four slide pots.

 

Hardware:

The SLIDER4 card has four slide potentiometers attached to a ten bit analog-to-digital converter. The ADC values are reported to the host 10 times per second. More information about the SLIDER4 card can be found here: cards/slider4.html.

 

Resources:

The interface to the slide4 lets you look at the most recent samples or to watch for values that have changed.

positions : pot positions in range of 0 to 1023.
This resource has the current positions of the slide pots as four space-separated decimal numbers in the range of 0 to 1023. A zero value indicates that the slide is close to the Baseboard connector. Use dpcat to monitor the pots for movement and dpget to get the most recently reported positions.

 

Examples:

Monitor the four slide pots for movement. dpcat slide4 positions
