ZUNO_SETUP_BATTERY_LEVELS()By default Z-Uno automatically maps battery voltage from 2.7V–3.0V to 0%–100% by measuring the voltage on the 3V3 pin. But some batteries might require different mapping. In thace case one can define the correct mapping. ZUNO_SETUP_BATTERY_LEVELS(min, max) min value corresponding to empty battery (0%) in mV, WORD max value corresponding to full battery (100%) in mV, WORD Battery is reported only if device is configured as sleeping (ZUNO_SLEEPING_MODE_SLEEPING or ZUNO_SLEEPING_MODE_FREQUENTLY_AWAKE). Ignored if ZUNO_SETUP_BATTERY_HANDLER() is specified.
