I haven't found any list for generic embedded linux questions so please
me if you know one.
I am working on a Freescale MX51 board with a MC13892 PMIC which has a
battery driver to
monitor and control the battery. If I were to develop a battery powered
device based on
it, I would need a way to monitor the charge, turn on/off the charger if
depending on battery level and suspend the system if the battery level
Some battery packs come with external chips that provide this functionality,
battery packs are not available if you are not bulk purchasing.
If I were to use the battery measurements provided by the PMIC to control
charge I would need to model the specific battery I am goint to use in terms
voltage/current graphs. Any known Linux effort towards this?
Also, could the typical laptop user space applications (gnome panel applet
et al) that
typically use ACPI be used on an embedded system? Are there any other
specifically targetted to the embedded market?
As you may guess it's the first time I work on a battery powered embedded
Thanks for your help,
