IMU - LSM303C

Breadboard for "IMU - LSM303C"

Fritzing diagram: docs/breadboard/imu-lsm303c.fzz

 

Run this example from the command line with:

node eg/imu-lsm303c.js

const {Board, IMU} = require("../");
const board = new Board();

board.on("ready", () => {

  // Hookup Guide
  // https://learn.sparkfun.com/tutorials/lsm303c-6dof-hookup-guide#hardware-assembly
  //
  // Basically uses I2C, so only 4 pins are needed:
  // VCC --> VDD
  // GND --> GND
  // SCL --> SCL
  // SDA --> SDA

  const layout = `
  Board layout:
       +---------------+
       |              *| GND
       |              *| VDD_IO
