Hi, Modifying JustFATLogging (or HostTimeLogging) to sample GSR instead of the accelerometer is very straightforward.
When you say "system time" do you mean the mote's idea of time (i.e. ticks of the onboard crystal) or real world time/clock time/wall time? If the latter you are probably better off starting with HostTimeLogging and modifying that. Additionally take a look at the recently released ParamLogging app ( http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-2.x-contrib/shimmer/apps/ParamLogging/) which allows you to configure which sensors are to be sampled by modifying a file that you load on the SD card (including GSR). The applications README explains how it works. However you should note that this app does not control the range of the GSR (dynamically or manually). If you need to be able to dynamically change the range setting (based on the input) then take a look at the SimpleGSR app for an example of how this can be done ( http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-2.x-contrib/shimmer/apps/SimpleGSR/ ) Mike On Mon, Jul 30, 2012 at 10:47 PM, Fola Alamudun <[email protected]>wrote: > Hello, > > I am very new to shimmer and nesC programming so i would appreciate all > the help i can get. > I want to write a program that is similar to JustFatLogging except that it > logs the following: > 1. timestamp (system time i suppose, similar to HostTimeLogging; and > 2.
