Maxim Integrated* MAX5487 is a dual, 256-tap, nonvolatile, SPI, linear-taper digital potentiometer. This module was tested on the Maxim Integrated MAX5487PMB1 PMOD module from the analog PMOD kit.

    upm::MAX5487 sensor(7);

    // Power LED UP
    for (int i = 0; i < 255; i++) {
        sensor.setWiperA(i);
        upm_delay_us(5000);
    }

    // Power LED DOWN
    for (int i = 0; i < 255; i++) {
        sensor.setWiperA(255 - i);
        upm_delay_us(5000);
    }

Member Function Documentation

void setWiperA

(

uint8_t

wiper

)

MAX5487 object destructor, closes all IO connections no more needed as the connections will be closed when m_spi and m_csnPinCtx will go out of scope ~MAX5487 (); Sets a wiper for port A.

void setWiperB

(

uint8_t

wiper

)

Sets a wiper for port B.

std::string name ( )

inline

Returns the name of the component
