Public Member Functions | |
smolPowerLiPo () | |
Create an object to communicate with the SparkFun smôl Power Board LiPo. | |
bool | begin (byte deviceAddress=SFE_SMOL_POWER_DEFAULT_I2C_ADDRESS, TwoWire &wirePort=Wire) |
float | getBatteryVoltage () |
![]() | |
bool | isConnected () |
Class to communicate with the SparkFun smôl Power Boards. More... | |
bool | setI2CAddress (byte address) |
Change the smôl Power Board AAA's I2C address. You will need to call .begin again using the new address to re-establish communication with the Power Board. More... | |
byte | getI2CAddress () |
Just for fun, read back the Power Board's I2C address. This proves that I2C communication is possible and that the Power Board has the correct address stored in eeprom. More... | |
byte | getResetReason () |
Read the reason for the ATtiny's most recent reset. More... | |
float | getTemperature () |
Read the ATtiny's internal temperature. TO DO: Add temperature calibration / correction functionality. More... | |
float | measureVCC () |
Measure the ATtiny43U's VCC by reading the 1.1V internal reference via the ADC. More... | |
bool | setADCVoltageReference (sfe_power_board_ADC_ref_e ref) |
Set the ATtiny43U's ADC voltage reference to VCC or the internal 1.1V reference. More... | |
sfe_power_board_ADC_ref_e | getADCVoltageReference () |
Get the ATtiny43U's ADC voltage reference: VCC or the internal 1.1V reference. More... | |
bool | setWatchdogTimerPrescaler (sfe_power_board_WDT_prescale_e prescaler) |
Set the ATtiny43U's Watchdog Timer prescaler to set the WDT interrupt rate. More... | |
sfe_power_board_WDT_prescale_e | getWatchdogTimerPrescaler () |
Get the ATtiny43U's Watchdog Timer prescaler setting. More... | |
bool | setPowerdownDurationWDTInts (uint16_t duration) |
Set the Power Board Power-down duration in Watchdog Timer interrupts. More... | |
bool | getPowerDownDurationWDTInts (uint16_t *duration) |
Get the Power Board Power-down duration in Watchdog Timer interrupts. More... | |
bool | powerDownNow () |
Power down the system now. The smôl bus power will be disabled. The ATtiny43U will wake up and turn the power back on after SFE_SMOL_POWER_REGISTER_POWERDOWN_DURATION WDT interrupts. More... | |
byte | getFirmwareVersion () |
Get the Power Board firmware version. More... | |
byte | computeCRC8 (byte data[], byte len) |
Given an array of bytes, this calculates the CRC8 for those bytes. From: http://www.sunshine2k.de/articles/coding/crc/understanding_crc.html Tested with: http://www.sunshine2k.de/coding/javascript/crc/crc_js.html x^8+x^5+x^4+1 = 0x31. More... | |

SMOL_POWER_BOARD_IO | smolPowerBoard_io |
Communication interface for the SparkFun smôl Power Board LiPo
float smolPowerLiPo::getBatteryVoltage | ( | ) |
This function reads the battery voltage from the MAX_17048 fuel gauge.
