API for the MAX5487 SPI Digital Potentiometer. More...

Detailed Description

• ID: max5487
• Name: MAX5487 Digital Potentiometer
• Category: digipot
• Manufacturer: maxim
• Connection: spi

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.

    sensor = new upm::MAX5487(7);

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

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

Constructor & Destructor Documentation

MAX5487

(

int

csn = -1

)

Instantiates an MAX5487 object

Parameters

csn	CSN to use, if any; by default, ICSP CS (-1) is used

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
