Library Description

The library contains a basic functions for using 8 pin I2C click.

Key functions:

• void c8pini2c_i2c_write(uint8_t slave_addr, uint8_t *data_buf,uint16_t len, uint8_t end_mode) - I2C Write function
• void c8pini2c_i2c_read(uint8_t slave_addr, uint8_t *data_buf,uint16_t len, uint8_t end_mode) - I2C Read function
• void c8pini2c_i2c_start ( void ) - I2C Start function

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initializes driver init and set up another click for test
• Application Task - Reads temperature and logs on the USB UART
• NOTE: Surface temp click board used for demonstrating work 8 pin I2C click-a

void application_task ( )
{
    float temperature;
    char demo_text[ 20 ];

    temperature = surfacetemp_get_temperature( );
    FloatToStr( temperature, demo_text );
    mikrobus_logWrite( "> Temperature : ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );
    Delay_ms( 1500 );
}

Other mikroE Libraries used in the example:

• I2C Library
• UART Library
• Conversions library

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.
