setVrefDrive()

Description

This function sets the current limiting for keeping run state of a stepper motor.

Syntax

step.setVrefDrive(vref)

Parameters

vref - a integer value which represents the current limiting (0 ~ 15)

Returns

none

Example

#include <PhpocExpansion.h>
#include <Phpoc.h>

byte spcId = 1;

ExpansionStepper step(spcId);

void setup() {
    Serial.begin(9600);
    while(!Serial)
        ;

    Phpoc.begin(PF_LOG_SPI | PF_LOG_NET);
    Expansion.begin();

    Serial.println(step.getPID());
    Serial.println(step.getName());

    step.setMode(4);
    step.setVrefStop(2);

    // sets the current limiting for run state
    step.setVrefDrive(8);
    step.setResonance(120, 250);
    step.setSpeed(400);
    step.setAccel(0, 0);
    step.setPosition(-400);

    step.stepGoto(400);
    delay(1000);
    step.stepGoto(-400);
    delay(1000);
    step.stepGoto(400);

    while(step.getState()) {
        delay(1);
    }
}

void loop() {
