Data logging using ez430-Chronos watch (Part 1: Firmware)November 6, 2010 at 1:37 am | Posted in ez430 chronos, MSP430, My Projects | 50 Comments
TI provides sample program for data logging using ez430-Chronos watch.
However, the code only logs ambient temperature and altitude.
It does not log the triaxial accelerometer data.
So, I modified TI’s data logger sample project (CCS) to record x-y-z data.
Go to the bottom of this post for the link to download the code.
A simple Windows application is also written to setup the watch: date-time, sampling period (1s), and the datalog mode (ACCELERATION + ALTITUDE + TEMPERATURE).
This same application also download the data from the watch, save into csv file and plot them in separate graph.
The watch only have enough memory to store up to 20 minutes worth of x,y,z,temp, and alt with 1Hz sampling rate.
Below is the sample data collected from playing Badminton last week.
Go HERE if you want to download the source code for the firmware.
I will release the code for the windows application on my next post.
