Library Description
The library covers all the necessary functions that enables the usage of the Qi RX Click board™. It offers reading from output register and calculations that result in relatively accurate measurement of connected batteries voltage.
Key functions:
uint16_t qirx_read_data ( ); - Function is used to read raw data from MCP3221.uint16_t qirx_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 :
void application_task ( )
{
voltage = qirx_read_voltage( v_ref );
WordToStr( voltage, log_txt );
Ltrim( 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 );
}

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.
