Library Description

The library covers all the necessary functions that enables the usage of the PowerBank 2 click board. It offers reading from output register and calculations that result in relatively accurate measurement of connected batteries voltage.

Key functions:

  • uint16_t powerbank2_read_data ( ); - Function is used to read raw data from MCP3221.
  • uint16_t powerbank2_read_voltage ( uint16_t v_ref ); - Function is used to calculate voltage of the connected battery.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes I2C module and LOG structure.
  • Application Initialization - Initalizes I2C driver and makes an initial log.
  • Application Task - This example shows the capabilities of the Power Bank 2 click by measuring voltage of the connected battery. In order to get correct calculations user should change "v_ref" value to his own power supply voltage.
void application_task ( )
{
    voltage = powerbank2_read_voltage( v_ref );
    WordToStr( voltage, log_txt );
    mikrobus_logWrite( "Battery voltage: ", _LOG_TEXT );
    mikrobus_logWrite( log_txt, _LOG_TEXT );
    mikrobus_logWrite( "mV", _LOG_LINE );

    mikrobus_logWrite( "------------------------", _LOG_LINE );
    Delay_ms( 2000 );
}


Other mikroE Libraries used in the example:

  • I2C
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

GPS 5 Click

0

GPS 5 Click is a compact add-on board that provides users with positioning, navigation, and timing services. This board features the M20050-1, a compact GPS module receiver using the MediaTek MT3333 flash chip, providing a complete GNSS receiver for optimum performance from Antenova. The receiver tracks 3 GNSS constellations concurrently (GPS+Galileo+GLONASS or GPS+Beidou) to considerably enhance location and TTFF (Time-to-first-fix) and has configurable low power modes operating from a 3.3V power supply. In addition to the possibility of using an external antenna, backup power, and various visual indicators, the M20050-1 also has an accurate 0.5ppm TXCO ensuring short TTFF alongside multi-path algorithms, which improves position accuracy in inner-city environments.

Ambient 18 Click

0

Ambient 18 Click is a compact add-on board used to sense the amount of the present ambient light. This board features the BH1680FVC, an analog current-output ambient light sensor from Rohm Semiconductor. The BH1680FVC can detect a wide range of illuminance up to 10klx and provides excellent responsivity close to the human eyes' response. Besides, it is also characterized by low sensitivity variation across various light sources, a built-in shutdown function, and the ability to process the output signal in analog or digital form. This Click board™ is the most suitable for obtaining ambient light data for adjusting brightness in applications that require power saving and better visibility.
