Washer-Motor-Control-Arduino

Arduino library to control Whirlpool Duet washing machine motor (3 phase 820W, P/N 8182793) through Motor Control Unit (MCU P/N 8181693).

An UART full-duplex to half-duplex adapter is required to connect Arduino hardware serial port to Washer MCU UART FULL DUPLEX TO HALF DUPLEX CONVERTER FOR MOTOR CONTROL UNIT 8181693

##Arduino hardware serial to half-duplex adapter wiring:

Arduino pin  ----   half-duplex adapter pin
   0 (RX)    ----       3 (RX)
   1 (TX)    ----       2 (TX)
   GND       ----       4 (GND)
   5V        ----       1 (VCC)

##API calls example:

    // initialize serial stream. could be hardware serial or software searial.
    // here shows using hardware serial
    Serial.begin(WPMCONTROL_SERIAL_BAUD, WPMCONTROL_SERIAL_CFG);

    // create an instance of the WPMControl
    WPMControl wpmcontrol;
    
    // tell WPMControl to use initialized serial    
    if (wpmcontrol.connect(Serial))
    {

        // start motor with provided speed, acceleration rate and direction (DIR_CW or DIR_CCW)
        // speed range from 500 - 12000 RPM
        // acceleration rate from 64 - 3200. acceleration number higher the sooner the motor reaches target speed.
        // direction could be DIR_CW (clockwise) or DIR_CCW (counter-clockwise)
        motorRunning = wpmcontrol.setSpeed(speed, acceleration, WPMControl::DIR_CW);
        
    } 

    // to stop motor. deceleration number higher the sooner the motor will stop. valid from 64 - 3200.
    wpmcontrol.stopMotor(deceleration); 

##DISCLAIMER - USE AT YOUR OWN RISK

SAFTY FIRST! The motor outputs more than 1 horse power, running speed up to 10k+ RPM!
