Click library

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

Software Support

We provide a library for the Alcohol2 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 Alcohol2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void alcohol2_cfg_setup ( alcohol2_cfg_t *cfg );

  • Initialization function.

    ALCOHOL2_RETVAL alcohol2_init ( alcohol2_t ctx, alcohol2_cfg_t cfg );

  • Click Default Configuration function.

    void alcohol2_default_cfg ( alcohol2_t *ctx );

Example key functions :

  • This function writes one byte to the register.

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

  • This function reads one byte from the register.

    uint8_t alcohol2_read_byte ( alcohol2_t *ctx, uint8_t reg );

  • This function reads Alcohol data.

    uint16_t alcohol2_read_alcohol ( alcohol2_t *ctx );

Examples Description

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

The demo application is composed of two sections :

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 );
} 

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.Alcohol2

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.

4-20mA T 2 Click

0

4-20mA T 2 Click is a compact add-on board for transmitting an analog output current over an industry-standard 4-20mA current loop. This board features DAC161S997, a low-power 16-bit ΣΔ digital-to-analog converter (DAC) from Texas Instruments. It has a programmable Power-Up condition and loop-error detection/reporting accessible via simple 4-wire SPI for data transfer and configuration of the DAC functions. In addition, it is characterized by low power consumption and the possibility of simple Highway Addressable Remote Transducer (HART) modulator interfacing, allowing the injection of FSK-modulated digital data into the 4-20mA current loop.
