Software Support

We provide a library for the Alcohol2 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in register. The library includes function for read Alcohol data.

Key functions :

• uint16_t alcohol2_readAlcohol() - Function for read Alcohol data
• void alcohol2_writeByte( uint8_t reg, uint8_t _data ) - Function writes one byte to the register.

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C bus and set AN pin as INPUT and RST pin as OUTPUT.
• Application Initialization - Initializes I2C driver and device configuration.
• Application Task - (code snippet) - Gets Alcohol (C2H5OH) data and logs data to USBUART every 500ms.

void applicationTask()
{
    Alcohol_Value = alcohol2_readAlcohol();
    FloatToStr( Alcohol_Value, demoText );
    mikrobus_logWrite( "Alcohol value : ", _LOG_TEXT );
    mikrobus_logWrite( demoText, _LOG_LINE );
    Delay_ms( 500 );
}

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• I2C
• Conversions

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.
