Click library

  • Author : Stefan Filipovic
  • Date : Feb 2024.
  • Type : One Wire type

Software Support

We provide a library for the 1-Wire I2C 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for 1-Wire I2C Click driver.

Standard key functions :

  • c1wirei2c_cfg_setup Config Object Initialization function.

    void c1wirei2c_cfg_setup ( c1wirei2c_cfg_t *cfg );
  • c1wirei2c_init Initialization function.

    err_t c1wirei2c_init ( c1wirei2c_t *ctx, c1wirei2c_cfg_t *cfg );
  • c1wirei2c_default_cfg Click Default Configuration function.

    err_t c1wirei2c_default_cfg ( c1wirei2c_t *ctx );

Example key functions :

  • c1wirei2c_reset_device This function resets the device by toggling the RST pin state.

    void c1wirei2c_reset_device ( c1wirei2c_t *ctx );
  • c1wirei2c_write_data This function addresses and writes 1-255 bytes to an I2C slave without completing the transaction with a stop.

    err_t c1wirei2c_write_data ( c1wirei2c_t *ctx, uint8_t slave_addr, uint8_t *data_in, uint8_t len );
  • c1wirei2c_read_data_stop This function is used to address and read 1-255 bytes from an I2C slave in one transaction.

    err_t c1wirei2c_read_data_stop ( c1wirei2c_t *ctx, uint8_t slave_addr, uint8_t *data_out, uint8_t len );

Example Description

This example demonstrates the use of 1-Wire I2C Click board by reading the temperature measurement from connected Thermo 4 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    c1wirei2c_cfg_t c1wirei2c_cfg;  /**< Click config object. */

    /** 
     * 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.
    c1wirei2c_cfg_setup( &c1wirei2c_cfg );
    C1WIREI2C_MAP_MIKROBUS( c1wirei2c_cfg, MIKROBUS_1 );
    if ( ONE_WIRE_ERROR == c1wirei2c_init( &c1wirei2c, &c1wirei2c_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( C1WIREI2C_ERROR == c1wirei2c_default_cfg ( &c1wirei2c ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement from connected Thermo 4 Click board and displays the results on the USB UART once per second.

void application_task ( void )
{
    float temperature = 0;
    uint8_t reg_data[ 2 ] = { 0 };
    uint8_t reg_addr = DEVICE_REG_TEMPERATURE;
    if ( ( C1WIREI2C_OK == c1wirei2c_write_data ( &c1wirei2c, DEVICE_SLAVE_ADDRESS, &reg_addr, 1 ) ) && 
         ( C1WIREI2C_OK == c1wirei2c_read_data_stop ( &c1wirei2c, DEVICE_SLAVE_ADDRESS, reg_data, 2 ) ) )
    {
        temperature = ( ( ( int16_t ) ( ( ( uint16_t ) reg_data[ 0 ] << 8 ) | 
                                                       reg_data[ 1 ] ) ) >> 5 ) * DEVICE_TEMPERATURE_RES;
        log_printf( &logger, "\r\n%s - Temperature: %.3f degC\r\n", ( char * ) DEVICE_NAME, temperature );
    }
    else
    {
        log_error( &logger, "%s - no communication!\r\n", ( char * ) DEVICE_NAME );
    }
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.1WireI2C

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. UART terminal is available in all MikroElektronika compilers.

RTC 19 Click is a compact add-on board that measures the passage of real-time. This board features the MAX31334, an I2C-configurable real-time clock with an integrated power switch from Analog Devices. The MAX31334 provides information like seconds, minutes, hours, days, months, years, and dates based on a 32.768kHz quartz crystal through an I2C serial interface to transmit time and calendar data to the MCU. It also has an alarm function that outputs an interrupt signal to the MCU when the day of the week, hour, or minute matches with the pre-set time, as well as a programmable square-wave output, event detection input with timestamping, and backup supply.
