GroveSlide Class Reference

API for the Grove Slide Potentiometer. More...

Detailed Description

Deprecated:

This class is being replaced by the upm-slide library and the Slide class.

• ID: groveslide
• Name: Slide Potentiometer
• Category: ainput
• Manufacturer: seeed
• Connection: analog

Basic UPM module for the Grove slide potentiometer on analog that returns either a raw value or a scaled voltage value.

    upm::GroveSlide slide(0);

    cout << slide.name() << endl;

    while (true) {
        float adc_value = slide.raw_value(); // Read raw value
        float volts = slide.voltage_value(); // Read voltage, board reference set at 5.0V
        fprintf(stdout, "%4d = %.2f V\n", (uint16_t) adc_value, volts);

        upm_delay_us(2500000); // Sleep for 2.5s
    }
