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.

Example 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 );
}

mikroE Libraries used in the example:

• I2C
• Conversions

Additional notes and information

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.
