Library Description

The library covers all the necessary functions to control the Voltmeter click board. Voltmeter click communicates with the device via SPI driver by reading from registers. This library contains drivers for generic read  ADC value, for calibrating and for voltage reading function.

Key functions:

  • uint16_t voltmeter_readData() - Generic read 16-bit data function.
  • void voltmeter_calibration() - Calibration reading function.
  • float voltmeter_getVoltage( uint8_t coefficient ) - Voltage reading function.

Examples description

The application is composed of three sections:

  • System Initialization - Initializes GPIO, I2C, and LOG structures set AN as input and INT pins output and start to write log.
  • Application Initialization -  Initialization driver enables - I2C, start calibration reading and also write log.
  • Application Task - (code snippet) This is an example which demonstrates the use of Voltmeter Click board. These examples read ADC value from the register of MCP3201 chip on the Voltmeter click board and calculate the voltage value [ mV ]. Results are being sent to the Usart Terminal where you can track their changes.
void applicationTask() 
{
    adcValue = voltmeter_readData();
    WordToStr( adcValue, logText );
    ltrim( logText );
    mikrobus_logWrite( " ADC Value: ", _LOG_TEXT );
    mikrobus_logWrite( logText, _LOG_LINE );
    
    voltage = voltmeter_getVoltage( _VOLTMETER_VCC_5V_COEFF_2 );
    FloatToStr( voltage, logText );
    ltrim( logText );
    mikrobus_logWrite( " Voltage  : ", _LOG_TEXT );
    mikrobus_logWrite( logText, _LOG_TEXT );
    mikrobus_logWrite( " mV ", _LOG_LINE );
    mikrobus_logWrite( "------------------------", _LOG_LINE );
    Delay_1sec();
}

  • SPI
  • UART​
  • Conversion

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
