| 1 # This is the "standard" charging config for Mot C1xx phones running | |
| 2 # FreeCalypso fw. The start threshold is set to "always" on the reasoning | |
| 3 # that if the user connects the charging power source (which is not USB | |
| 4 # and thus not required for computer connection), it means that she | |
| 5 # actually intends to charge the battery, the charge-to voltage is the | |
| 6 # full charge (charge the battery fully before going out), and the | |
| 7 # restart threshold is a reasonable setting so if the phone is left | |
| 8 # plugged into the charger for a long time, the user won't be surprised | |
| 9 # with a battery that has run down significantly after the completion | |
| 10 # of the initial charging cycle. | |
| 11 | |
| 12 start-threshold always | |
| 13 restart-threshold 3900 # mV | |
| 14 charge-to-voltage 4200 # mV | |
| 15 overvoltage 4280 # mV | |
| 16 | |
| 17 # For the current settings, keep in mind that C1xx phones use a current | |
| 18 # measurement resistor of 0.15R instead of TI's "canonical" value of 0.20R, | |
| 19 # hence the conversion factor between mA and ADC/DAC numbers changes | |
| 20 # accordingly. The CI current setting is based on what Motorola's fw | |
| 21 # has been observed to set, but the end current setting is our own. | |
| 22 | |
| 23 ci-current 280 # DAC units, about 320 mA | |
| 24 end-current 88 # ADC units, about 100 mA | |
| 25 | |
| 26 # Motorola's fw does not seem to use the I2V offset mechanism, | |
| 27 # but we use the same setting as Pirelli. | |
| 28 | |
| 29 i2v-offset 0x18 # register setting |
