Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Voltmeter Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Voltmeter Click driver.

Standard key functions :

  • voltmeter_cfg_setup Config Object Initialization function.

    void voltmeter_cfg_setup ( voltmeter_cfg_t *cfg ); 
  • voltmeter_init Initialization function.

    err_t voltmeter_init ( voltmeter_t *ctx, voltmeter_cfg_t *cfg );

Example key functions :

  • voltmeter_read_raw_data This function reads raw ADC value.

    int16_t voltmeter_read_raw_data ( voltmeter_t *ctx );
  • voltmeter_calculate_voltage This function converts the raw ADC value to proportional voltage level.

    float voltmeter_calculate_voltage ( voltmeter_t *ctx, int16_t raw_adc, uint8_t iso_gnd );

Example Description

This application reads the voltage measurement and displays the results on the USB UART.

The demo application is composed of two sections :

Application Init

Initialization the driver and logger.


void application_init ( void )
{
    log_cfg_t log_cfg;
    voltmeter_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    //  Click initialization.
    voltmeter_cfg_setup( &cfg );
    VOLTMETER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    voltmeter_init( &voltmeter, &cfg );
    Delay_ms ( 100 );

    log_info( &logger, " Application Task " );
}

Application Task

Reads the raw ADC measurement once per second and converts it to the proportional voltage level. All data are being displayed on the USB UART where you can track their changes.


void application_task ( void )
{
    int16_t adc_value = 0;
    float voltage = 0;

    adc_value = voltmeter_read_raw_data( &voltmeter );
    log_printf( &logger, " ADC Value: %d\r\n", adc_value );

    voltage = voltmeter_calculate_voltage( &voltmeter, adc_value, VOLTMETER_GND_ISO );
    log_printf( &logger, " Voltage  : %.3f V\r\n", voltage );
    log_printf( &logger, "------------------------\r\n");
    Delay_ms ( 1000 );
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Voltmeter

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.
