Click library

  • Author : MikroE Team
  • Date : Sep 2020.
  • Type : I2C type

Software Support

We provide a library for the 8pinI2c 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 8pinI2c Click driver.

Standard key functions :

  • Config Object Initialization function.

    void c8pini2c_cfg_setup ( c8pini2c_cfg_t *cfg );

  • Initialization function.

    C8PINI2C_RETVAL c8pini2c_init ( c8pini2c_t ctx, c8pini2c_cfg_t cfg );

Example key functions :

  • Generic write function.

    void c8pini2c_generic_write ( c8pini2c_t ctx, uint8_t slave_addr, uint8_t reg, uint8_t data_buf, uint8_t len );

  • Generic read function.

    void c8pini2c_generic_read ( c8pini2c_t ctx, uint8_t slave_addr, uint8_t reg, uint8_t data_buf, uint8_t len );

Examples Description

This demo example reads temperature detected by Surface temp Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and configures a Surface temp Click board.


void application_init ( void )
{
    log_cfg_t log_cfg;
    c8pini2c_cfg_t cfg;

    uint8_t status;

    /** 
     * 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 ----" );

    //  Click initialization.

    c8pini2c_cfg_setup( &cfg );
    C8PINI2C_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c8pini2c_init( &c8pini2c, &cfg );

    status = surfacetemp_setup( );
    if ( status == 0 )
    {
        log_printf( &logger, "--- INIT DONE --- \r\n" );
    }
    else
    {
        log_printf( &logger, "--- INIT ERROR --- \r\n" );
        for( ; ; );
    }
}

Application Task

Reads the temperature detected by Surface temp Click board and logs it on the USB UART each second.


void application_task ( void )
{
    float temperature;

    temperature = surfacetemp_get_temperature( );
    log_printf( &logger, "> Temperature : %.2f Celsius\r\n", temperature );
    Delay_ms ( 1000 );
} 

Note

In order to run this example successfully, a Surface temp Click board needs to be connected properly to an 8-pin I2C Click board.

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.8pinI2c

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.
