This page is to bring together efforts and links for those working on understanding BME - the battery managment entity.
This is required to implement user friendly Host Mode
BME is divided into three parts.
- Kernel driver that handles all of the low-level interaction with the hardware.
- hald-addon-bme - an add-on process for HAL that reports status.
- bme_RX-51 - Process started early in boot, with watchdogs to reboot the device if it malfunctions.
The kernel driver is split over several files.
http://mxr.maemo.org/fremantle/source/kernel/include/linux/i2c/twl4030-madc.h This handles reading various ADCs to readout voltages and currents.
