There are two projects that are built-in, provided by Texas Instruments: One is the standard project which handles all the fitness capabilities, time and wireless updates. The second is the data logger application. The data logger is similar to the first project in that it tells time, transmit the watch and receive heart rates, etc. The difference is that a lot of functionality that has been left out like the accelerometer code is not exposed. The reason for this is to leave a certain chunk of the Flash available to log information directly to the Flash. TI also has provided a small GUI to graphically configure what the user requires, to choose what is collected and what sampling rates to collect at from one and 255 seconds. 8K of Flash is reserved specifically for data logging. Additionally, the data collected can be wirelessly downloaded and saved as a CSD file for use in Excel.
