// APPLICATION LIBRARIES
// Include the temperature/humidity sensor Library
#require "HTS221.device.lib.nut:2.0.2"
// APPLICATION CONSTANTS
// The I2C address for the sensor
const I2C_ADDR = 0xBE;
// APPLICATION GLOBALS
// Set up the imp I2C bus the sensor is connected to
i2c <- hardware.i2cLM;
i2c.configure(CLOCK_SPEED_400_KHZ);
// Initialize the sensor...
tempHumid <- HTS221(i2c, I2C_ADDR);
// ...and configure it to take a single
// reading when we call the read() method.
tempHumid.setMode(HTS221_MODE.ONE_SHOT);
// Set up the user LED for the colours we’ll flash
// to indicate successful or failed readings
redPin <- hardware.pinR;
redPin.configure(DIGITAL_OUT, 0);
greenPin <- hardware.pinXA;
greenPin.configure(DIGITAL_OUT, 0);
// Define a variable we'll use later
ledPin <- null;
// APPLICATION FUNCTIONS
function loop() {
// This is the primary loop, run every ten seconds
// Take a reading

// Check the result

// Queue up a timer to fire in 1 second and turn off the LED
// Note that unlike 'loop()', here we pass in an anonymous function
// rather than a reference to function

}
// APPLICATION RUNTIME
// Start taking periodic readings
