I just got the msp430G2 launchpad with the MSP430G2553 mcu. For stepper motor driver im using the boost-drv8711 boosterpack. I was able to get it running with the tutorial that it came with. However i cant run it with Energia. It might be because of the enable bit (0x0) but i dont know how to set it 1 on energia. Do any of you have any experiance of this setup ? The motor im running is bipolar sanyo denki 103h5208-5240. My code so far is like this (i used the arduino example, board pin layouts in attachment):
#include <Stepper.h>
const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution
// for your motor
// These are the pins for the driver STEP/AIN1 , DIR/AIN2, BIN1,BIN2
Stepper myStepper(stepsPerRevolution, 9, 10, 12, 13);
void setup() {
pinMode(9, OUTPUT); // same as above
pinMode(10, OUTPUT);
pinMode(12, OUTPUT);
pinMode(13, OUTPUT);
pinMode(6, OUTPUT); // pin for the nSleep which wakes up the board
digitalWrite(6, HIGH);
// set the speed at 60 rpm:
myStepper.setSpeed(60);
// initialize the serial port:
Serial.begin(9600);
}
void loop() {
// step one revolution in one direction:
Serial.println("clockwise");
myStepper.step(stepsPerRevolution);
delay(100);
// step one revolution in the other direction:
Serial.println("counterclockwise");
myStepper.step(-stepsPerRevolution);
delay(100);
}
