EDUMKII AccelerometerSerial

This Example uses the Accelerometer and reports the data through the Serial Monitor.

Hardware Required

  • TI LaunchPad

  • Educational BoosterPack MKII


None. This basic example just uses your LaunchPad and BoosterPack only.


 ADXL3xx 3-axis accelerometer example for Educational BoosterPack MK II

 Absolute rating/conversion can be determined from the ADXL3xx datasheet.
 As a quick reference, for LaunchPads with 12-bit ADC (MSP430F5529, Tiva C, etc.),
 the entire analog  range is [0,4096]. For simple tilting calculation
 [-1g,1g] ~ = [mid-800, mid + 800] = [2048-800,2048+800] = [1248,2848]

 Modified from ADXL3xx example by David A. Mellis & Tom Igoe

 Reads an Analog Devices ADXL3xx accelerometer and communicates the
 acceleration to the computer.  The pins used are designed to be easily
 compatible with the breakout boards from Sparkfun, available from:

 The circuit:

 * analog 25: z-axis
 * analog 24: y-axis
 * analog 23: x-axis

 This example code is in the public domain.


const int xpin = 23;                  // x-axis of the accelerometer
const int ypin = 24;                  // y-axis
const int zpin = 25;                  // z-axis (only on 3-axis models)

void setup()
  // By default MSP432 has analogRead() set to 10 bits.
  // This Sketch assumes 12 bits. Uncomment to line below to set analogRead()
  // to 12 bit resolution for MSP432.

  // initialize the serial communications:

void loop()
  // print the sensor values:
  Serial.print(((int) analogRead(xpin)) - 2048);
  // print a tab between values:
  Serial.print(((int) analogRead(ypin)) - 2048);
  // print a tab between values:
  Serial.print(((int) analogRead(zpin)) - 2048);
  // delay before next reading:
