Connecting the VFD Clock BoosterPack

Step 1 - Solder the Crystal

Your Launchpad should have shipped with a 13.768kHz crystal. To provide more accurate accurate time-keeping clock, you'll need to solder it to your Launchpad. Instructions for soldering your crystal can be found here

Alternately - you may uncomment the define for NOXTAL in main.c, but time kept by the device will be less accurate.

Once you've soldered your crystal - you may find it helpful to test it using this code - File:Msp430g2xx3 LFxtal This is a code sample provided by Texas Instruments as part of the code samples for the MSP430G2553. If your crystal is soldered correctly, the red LED on your Launchpad should pulse every second. Otherwise - the red LED will toggle quickly, indicating a fault.
