# This is the "standard" charging config for Mot C1xx phones running # FreeCalypso fw. The start threshold is set to "always" on the reasoning # that if the user connects the charging power source (which is not USB # and thus not required for computer connection), it means that she # actually intends to charge the battery, the charge-to voltage is the # full charge (charge the battery fully before going out), and the # restart threshold is a reasonable setting so if the phone is left # plugged into the charger for a long time, the user won't be surprised # with a battery that has run down significantly after the completion # of the initial charging cycle. start-threshold always restart-threshold 3900 # mV charge-to-voltage 4200 # mV overvoltage 4280 # mV # For the current settings, keep in mind that C1xx phones use a current # measurement resistor of 0.15R instead of TI's "canonical" value of 0.20R, # hence the conversion factor between mA and ADC/DAC numbers changes # accordingly. The CI current setting is based on what Motorola's fw # has been observed to set, but the end current setting is our own. ci-current 280 # DAC units, about 320 mA end-current 88 # ADC units, about 100 mA # Motorola's fw does not seem to use the I2V offset mechanism, # but we use the same setting as Pirelli. i2v-offset 0x18 # register setting
