Click library

  • Author : MikroE Team
  • Date : nov 2019.
  • Type : I2C type

Software Support

We provide a library for the Alcohol3 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 Alcohol3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void alcohol3_cfg_setup ( alcohol3_cfg_t *cfg );

  • Initialization function.

    ALCOHOL3_RETVAL alcohol3_init ( alcohol3_t ctx, alcohol3_cfg_t cfg );

  • Click Default Configuration function.

    void alcohol3_default_cfg ( alcohol3_t *ctx );

Example key functions :

  • This function reads CO (Carbon monoxide) data in ppm (1 ppm - 1000 ppm).

    uint16_t alcohol3_get_co_in_ppm ( alcohol3_t *ctx );

  • This function reads percentage of alcohol in the blood (BAC).

    float alcohol3_get_percentage_bac ( alcohol3_t *ctx );

  • This function reads 12bit ADC value.

    uint16_t alcohol3_get_adc_data ( alcohol3_t *ctx );

Examples Description

Code of this sensor reacts to the presence of deoxidizing and reducing gases, such as ethanol (also known as alcohol).

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.


void application_init ( void )
{
    log_cfg_t log_cfg;
    alcohol3_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_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, "     Application  Init\r\n" );
    Delay_ms ( 100 );

    //  Click initialization.

    alcohol3_cfg_setup( &cfg );
    ALCOHOL3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    alcohol3_init( &alcohol3, &cfg );

    log_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, " ---- Alcohol 3 Click ----\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 1000 );

    log_printf( &logger, " ---- Initialization ---\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 1000 );
}

Application Task

Reads percentage of alcohol in the blood (BAC) and this data logs to USBUART every 1 sec.


void application_task ( void )
{
    uint16_t co_ppm;
    uint16_t p_bac;

    //  Task implementation.

    log_printf( &logger, " --- Alcohol diagnostics ---- \r\n" );

    co_ppm = alcohol3_get_co_in_ppm ( &alcohol3 );
    log_printf( &logger, " co in ppm  %d    | \r\n", co_ppm );

    p_bac = alcohol3_get_percentage_bac( &alcohol3 ) * 1000;

    if ( 10 > p_bac && p_bac < 100 )
    {
        log_printf( &logger, " BAC    %d  | 0.00\r\n", p_bac );
    }
    else if ( 100 <= p_bac && 1000 > p_bac )
    {
        log_printf( &logger, " BAC    %d  | 0.00\r\n", p_bac );
    }
    else if ( p_bac >= 1000 )
    {
        log_printf( &logger, " BAC    %d  | 0.\r\n", p_bac );
    }
    else
    {
        log_printf( &logger, " BAC  | 0.0000\r\n" );
    }
    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.Alcohol3

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.

Piezo Accel 2 Click - 50g is a compact add-on board for precise vibration and motion monitoring in condition-based maintenance applications. This board features the 830M1-0050, a triaxial piezoelectric accelerometer from TE Connectivity, capable of detecting motion and acceleration along all three axes (X, Y, Z). The 830M1-0050 offers a ±50g range with a sensitivity of 25mV/g, providing reliable and accurate analog voltage outputs. It integrates a built-in RTD temperature sensor for simultaneous vibration and temperature monitoring, and the onboard MCP3562R 24-bit ADC converts these signals into high-resolution digital data. Communication is made through an SPI interface with additional interrupt and clock functionality for easy integration with a host MCU.
