# Values for the development device

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.

  # Float charge battery voltage threshold (in mV).
  # stop charging if battery voltage reaches this threshold

  # Minimum voltage difference to U_bat that the solar panels must produce
  # before charging is resumed after it was switched off (in mV).

  # Delay between charging switch state change and sleep state check(in ms).
  SLEEP_SWITCH_DELAY: 1000

  # 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.

  # Voltage below which the load is turned off (in mV).
  U_BAT_LOAD_OFF: 24000

  # 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.
