Reading Acceloerometer on Chronos

The wiki is a great resource: Chronos Wiki. If you have not already done so, you can find development software and firmware to download there under the "Projects" section.

Using the USB you can program the watch and update the software/firmware to work with Chronos Control Center and see the functionality of the Chronos, such as the accelerometer.

Also on the Wiki are links for the SimpliciTI and Blue Robin wireless protocols.

Hope this helps.

Nishant:

Thanks, but I did not see firmware/code that does this function anywhere on the wiki? I need the information regarding the protocol between the watch  and the control center though the USB com port.  Please let me know. 

Asking around I found that many users reverse engineer the source using .NET or a Sniffer. There is a forum post a user posted with his/her findings: http://e2e.ti.com/support/microcontrollers/msp43016-bit_ultra-low_power_mcus/f/166/t/32714.aspx

Please let me know if this helps.

Thanks, but the real question is how to interpreted those value? I have been looking all over TI and WEB and everyone has the same question with no answers? The raw value from the com port is converted to numbers for X, Y and Z in the yellow window of Control Center. How the Control Center software converts the raw data to numbers in the bottom yellow window of the Control Center? I using the raw data to do the XYZ graph and the number goes from 0 to 255 in no time. My graph is not smooth as the Control Center graph.

Paul,

I will continue to explore into this for a better answer for you.
