Since there are four distinctive properties that can be measured with Multimeter Click which all require different measuring techniques, several different ICs had to be used on the Click board™. Starting with the high-quality, low noise A/D converter as the primary component, all the way to the input operational amplifiers, all components were hand-picked to ensure accuracy.

Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

We provide a library for the Multimeter 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 Multimeter Click driver.

Standard key functions :

  • Config Object Initialization function.

    void multimeter_cfg_setup ( multimeter_cfg_t *cfg );

  • Initialization function.

    MULTIMETER_RETVAL multimeter_init ( multimeter_t ctx, multimeter_cfg_t cfg );

  • Click Default Configuration function.

    void multimeter_default_cfg ( multimeter_t *ctx );

Example key functions :

  • This function reads and returns resistance data.

    float multimeter_read_resistance ( multimeter_t *ctx );

  • This function reads and returns voltage data.

    float multimeter_read_voltage ( multimeter_t *ctx );

  • This function reads and returns current data.

    float multimeter_read_current ( multimeter_t *ctx );

Examples Description

This example showcases how to configure, initialize and use the Multimeter Click. The Click measures resistance in Ohms, voltage in mVs, current in mAs and capacitance in nFs using a dual CMOS and quad CMOS op-amps, an ADC and other on board modules.

The demo application is composed of two sections :

Application Init

This function initializes and configures the logger and Click modules. Additional calibration of the measurement components is done in the default_cfg(...) function.


void application_init ( )
{
    log_cfg_t log_cfg;
    multimeter_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.

    multimeter_cfg_setup( &cfg );
    MULTIMETER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    multimeter_init( &multimeter, &cfg );
    multimeter_default_cfg( &multimeter );
}

Application Task

This function measures and displays resistance, voltage, current and capacitance data. It does so every second.


void application_task ( )
{
    float resistance;
    float voltage;
    float current;
    float capacitance;

    resistance = multimeter_read_resistance( &multimeter );
    log_printf( &logger, " * Resistance: %.3f Ohms * \r\n", resistance );

    voltage = multimeter_read_voltage( &multimeter );
    log_printf( &logger, " * Voltage: %.3f mV * \r\n", voltage );

    current = multimeter_read_current( &multimeter );
    log_printf( &logger, " * Current: %.3f mA * \r\n", current );

    capacitance = multimeter_read_capacitance( &multimeter );
    log_printf( &logger, " * Capacitance: %.3f nF * \r\n", capacitance );

    log_printf( &logger, "------------------------\r\n" );
    Delay_1sec( );
} 

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.Multimeter

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.

H-Bridge 7 Click features flexible motor driver IC for a wide variety of applications, labeled as the DRV8876N. This Click board™ integrates an N-channel H-bridge, charge pump regulator, and protection circuitry. The charge pump improves efficiency by allowing for both high-side and low-side N-channels MOSFETs and 100% duty cycle support. This IC allows the H-Bridge 7 Click to achieve ultra-low quiescent current draw by shutting down most of the internal circuitry with his low-power sleep mode.
