To test the LCD displayfollow the next steps

1. Grab Contiki and prepare the development setup (skip if you already have it)

2. Connect the LCD display to the RE-Mote using the 5-pin cable as shown in the photo above. This is a 5-pin connector with 2.54 mm pitch spacing, if you are to connect using a different cable than the one provided, check out the RE-Mote pin-out and the connector information.

3. Note the LCD works over 5V, you need to power the RE-Mote either by an external power supply or USB. One way to power the LCD from the RE-Mote, use the D+5.1 pin. as shown in the photo above.

4. Compile the test example and program the RE-Mote:
