Sensor, multiplexer

Mindstorms sensor multiplexer example

This example shows how to use the Mindsensors sensor multiplexer to read three touch sensors with a single sensor port.

With the call to sensorSetType the correct sensor is displayed in the simulator, this call is not necessary for the application to run in the VM.

By making a call to the msStart0 procedure the application starts registering multiplexer changes and writes them to the msTouch0 array.

#project "Multi sensor demo"

#include "lib/modules/standard.whl"

#display "EV3 Sensors"

proc main()
    ; Set the sensor type...
    sensorSetType(INPUT_1, SENSOR_TYPE_MULTIPLEXER)

    setTextSize(2)
    msStart0() ; Start reading the multiplexer on port 1

    repeat
        ; Draw the input state from the multiplexer on port 1
        drawNumber(20, 20, msTouch0[0])
        drawNumber(50, 20, msTouch0[1])
        drawNumber(80, 20, msTouch0[2])
        updateScreen()
    end
end
