# This is the "standard" charging config for Mot C1xx phones running
# FreeCalypso fw.  The key points are:
#
# 1) The battery is charged to the full 4.2 V, not a lower voltage,
# for traditional mobile phone usage patterns in which the user charges
# the battery fully before going out.
#
# 2) The start threshold is set fairly high 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, but it is set to 4100 mV instead of "always"
# so that if the battery is really full, an explicit AT@CHG=1 command
# or a future UI equivalent will be needed to force a charging start.
#
# 3) 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			4100	# mV
restart-threshold		3900	# mV

# Constant Voltage charging parameters mostly copied from Pirelli

ci2cv-threshold			4245	# mV, lowered from Pirelli's 4250
cv-initial-setpoint		4220	# mV
cv-ctrl-loop-high		4236	# mV
cv-ctrl-loop-low		4170	# mV, bumped up from Pirelli's 4160
cv-dac-max-incr			8	# DAC units
cv-dac-max-decr			50	# DAC units
cv-ctrl-loop-sample-count	6	# our logic is simpler than Pirelli's
overvoltage			4280	# mV, bumped up from Pirelli's 4270

# 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,
# chosen empirically.

ci-current			280	# DAC units, about 320 mA
end-current			60	# ADC units, about 68 mA
ichg-max-spike			26	# ADC units, about 30 mA
ichg-low-samples-needed		30	# sample count

# The apppropriate charging time limit and restart delay have yet to be
# determined; for now we give it a super-generous 6 h charging time limit
# and 2 h restart delay.

# Motorola's fw does not seem to use the I2V offset mechanism,
# but we use the same setting as Pirelli.
