Library description

Initializes click driver functions and I2C bus driver. Offers options for single or block writing to registers and reading from registers. Also offers options for calculating power and different types of voltage in a different number of samples and different full-scale range. For more details check the documentation.

Key functions

float pac1921_getMeasurementData( const uint8_t data_type, const uint8_t nSamples, const uint8_t full_scale ) - The function returns measurement data determined by the data_type parameter, which can be VSENSE (max 100mV), VBUS (max 32V) in mV, or VPOWER (max 320W) witch unit is W. One round of measurement consists of the determined number of samples.

void pac1921_blockReadReg( uint8_t register_address, uint8_t *data_buffer, uint8_t nBytes ) - The function reads bytes from registers to buffer with start location determined by the register_address parameter.

void pac1921_singleWriteReg( uint8_t register_address, uint8_t transfer_data ) - The function writes one byte of data to the register, determined by the parameter of the function.

The application is composed of three sections :

  • System Initialization - Initializes peripherals and pins.
  • Application Initialization - Initializes click driver.
  • Application Task - (code snippet) - Gets VBUS measurement data which is measured in 512 samples.
    Results are logged on the USB UART and measurement are repeated every 500ms.
void applicationTask()
{
    data_read = pac1921_getMeasurementData( _PAC1921_VBUS_FREE_RUN, _PAC1921_512_SAMPLES );

    FloatToStr( data_read, text );
    mikrobus_logWrite( text, _LOG_TEXT );
    if ( _PAC1921_UNIT == 0 )
    {
        mikrobus_logWrite( " mV", _LOG_LINE );
    }
    else
    {
        mikrobus_logWrite( " W", _LOG_LINE );
    }

    Delay_ms( 500 );
}

Additional notes and information

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.
