The IS31FL3731 is a compact LED driver for up to 144 single LEDs.

It can be used as follows:

// Call at boot time
var i2c = new I2C();
i2c.setup({sda:D27,scl:D28}); // use the I2C pins you're using here
g = require("IS31FL3731").connect(i2c);
// g is an instance of Graphics
// Send the changes to the screen

g is an instance of the Graphics class that is 16 pixels wide, 9 pixels high, and 8 bits per pixel (so it can output greyscale);
