# Values for the device at the B26 tower
calibration:
# Calibration factor defined here are divided by 1000 to determine the actual
# scaling factor. Therefore, if the voltage determined by the firmware is 2%
# lower than the actual voltage, you have to scale by 1.02 and therefore
# specify 1020 in this list.

# Maximum allowed microcontroller temperature (in units of 0.1 °C). If this
# temperature is exceeded, charging is stopped. The load is kept on. Do not
# set this too high as the heat has to propagate from the power MOSFETs.

# Resume operation below this temperature (in units of 0.1 °C).
INTERNAL_TEMPERATURE_RECOVERY: 450
# Minimum allowed external (BMP280) temperature (in units of 0.1 °C). If the

# the battery.

# Measurement Averaging:
# Alpha is specified in units of 1/1000. 1000 means that only the latest
# value is relevant, 0 means that the measurement has no influence. The latter
# is useless.
#
# The formula to calculate the next averaged value avg from a measurement meas is:
# avg[k] = meas * (alpha/1000) + avg[k-1] * (1 alpha/1000)
#
# For overload protection (battery voltage, load current), the latest values
# are always used.
