Charger click carries both a battery charger controller and a battery charge monitor. The smaller chip is MCP73831, a single-cell Li-Ion and Li-Polymer charge management controller. The larger IC is DS2438, a smart battery monitor. The monitor communicates with the MCU through a 1-Wire interface. The click is designed to use a 5V power supply.

The library covers all the necessary functions to control Charger click board. The library performs the communication with the device via 1-Wire protocol by writing to registers and by reading from registers.
Key functions:
void charger_gpioDriverInit (T_CHARGER_P gpioObj)
- Function initializes GPIO driver for the desired MIKROBUS1.Examples description
The application is composed of the three sections :
void applicationTask() { charger_getBatteryVoltage(); Delay_100ms(); mikrobus_logWrite( " Battery Voltage : ", _LOG_TEXT ); FloatToStr( batteryVoltage, logText ); mikrobus_logWrite( logText, _LOG_TEXT ); mikrobus_logWrite( " V", _LOG_LINE ); mikrobus_logWrite( " Charger Current : ", _LOG_TEXT ); FloatToStr( chargerCurrent, logText ); mikrobus_logWrite( logText, _LOG_TEXT ); mikrobus_logWrite( " mA", _LOG_LINE ); charger_getBatteryCapacity(); Delay_100ms(); mikrobus_logWrite( " Charger Capacity : ", _LOG_TEXT ); FloatToStr( chargerCapacity, logText ); mikrobus_logWrite( logText, _LOG_TEXT ); mikrobus_logWrite( " mAhr", _LOG_LINE ); mikrobus_logWrite( "---------------------------------", _LOG_LINE ); Delay_1sec(); }

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
