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 clickUSB 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.

I2C Isolator 6 Click

0

I2C Isolator 6 Click is a compact add-on board that offers completely isolated bidirectional communication. This board features the ADUM2250, a two-channel, 5kVRMS I2C digital isolator from Analog Devices. The ADUM2250 provides two bidirectional channels, supporting a completely isolated I2C interface that eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers. It supports data rates from DC up to 1MHz and has a hot swap circuitry to prevent data glitches.
