Jeff,
I am using the TS-BAT3 with 7260. I am doing an SD card boot (2.4
kernel) so these are my steps.
* in /linuxrc (load the bat modules) This will enable the TS7260 to
control the TS-bat3 including going to sleep at a later stage.
* Run whatever I want in /linuxrc. Ex. I am getting data from a weather
station, writing to a log and then sending it via Iridium. I call this
program also in /linuxrc after the ts-bat3 files have been loaded
* Do a 'sync' to make sure the buffers are all flushed and everything is
written to the disk (SD card).
* Call the sleep function of the TS-bat3. This basically shuts off power
to the 7260 abruptly (hence the sync). After time has elapsed, bat3 will
supply power to the 7260 (waking it up). And the circle of life continues...
There are few things that you need to be aware.
* JP7 on 7260 needs to be enabled for TS-bat3 to supply power to the
7260. Make sure you also do not power the board when using the bat3
* ts-bat3 just shuts off power so you need to do sync or risk corrupting
your data.
* Sleep time is the time the system is off. So if want the system to
come up every 300 seconds, you need to calculate the sleep time plus the
time of operation=300.
* There are battery charging routines but I am not using them as the
bat3 is using power from lead acid battery in my setup.
Cheers,
-Satish.
