MonoBattery::CalculatePercentage(uint16_t voltage, const uint16_t lookupTable[100])¶ Calculate percentage of battery remaining.
Percentage is calculated using a simple lookup-table of 100 voltage values, in millivolts:
- if voltage < lookupTable[0], return 0
- else if voltage < lookupTable[1], return 1
- ...
- else if voltage < lookupTable[99], return 99
- else return 100
- Return
- Percentage of battery remaining
- Parameters
voltage-Battery voltage as returned by ReadMilliVolts
lookupTable-Custom lookup-table to use
-
uint16_t
MonoBattery::ReadMilliVolts()¶ Read the battery voltage in millivolts.
To get higher accuracy battery voltage is sampled multiple times and average of these is returned.
Shortly after Mono has been reset, battery voltage can’t be read. In this case 0 is returned.
- Return
- The battery voltage in mV

uint8_t
MonoBattery::ReadPercentage(const uint16_t lookupTable[100])¶ Read the battery voltage and return percentage remaining.
See CalculatePercentage for details of how percentage is calculated.
- Return
- Percentage of battery remaining
