Alcohol 2 Click

Alcohol 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

The demo application gets Alcohol data and logs data to USBUART.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Alcohol2

Example Key Functions

• alcohol2_cfg_setup Config Object Initialization function.

void alcohol2_cfg_setup ( alcohol2_cfg_t *cfg );

• alcohol2_init Initialization function.

err_t alcohol2_init ( alcohol2_t *ctx, alcohol2_cfg_t *cfg );

• alcohol2_default_cfg Click Default Configuration function.

void alcohol2_default_cfg ( alcohol2_t *ctx );

• alcohol2_write_byte This function writes one byte to the register.

void alcohol2_write_byte ( alcohol2_t *ctx, uint8_t reg, uint8_t w_data );

• alcohol2_read_byte This function reads one byte from the register.

uint8_t alcohol2_read_byte ( alcohol2_t *ctx, uint8_t reg );

• alcohol2_read_alcohol This function reads Alcohol data.

uint16_t alcohol2_read_alcohol ( alcohol2_t *ctx );

Application Init

Initializes device configuration.

oid application_init ( void )
{
    log_cfg_t log_cfg;
    alcohol2_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 ----\r\n" );

    //  Click initialization.

    ALCOHOL2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    alcohol2_init( &alcohol2, &cfg );

    alcohol2_write_byte( &alcohol2, ALCOHOL2_MODECN_REG, ALCOHOL2_DEEP_SLEEP_MODE );
    alcohol2_write_byte( &alcohol2, ALCOHOL2_LOCK_REG,   ALCOHOL2_WRITE_MODE );
    alcohol2_write_byte( &alcohol2, ALCOHOL2_TIACN_REG, ALCOHOL2_EXT_TIA_RES | ALCOHOL2_100_OHM_LOAD_RES );
    alcohol2_write_byte( &alcohol2, ALCOHOL2_REFCN_REG, ALCOHOL2_VREF_INT | ALCOHOL2_50_PERCENTS_INT_ZERO | ALCOHOL2_BIAS_POL_NEGATIVE | ALCOHOL2_0_PERCENTS_BIAS );

    log_printf( &logger, "Alcohol 2 is initialized\r\n");
    Delay_ms ( 300 );
}

Application Task

Gets Alcohol (C2H5OH) data and logs data to USBUART every 500ms.

void application_task ( void )
{
    alcohol_value = alcohol2_read_alcohol( &alcohol2 );
    log_printf( &logger, "Alcohol value : %f \r\n",alcohol_value );
    Delay_ms ( 500 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
