Click library

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

Software Support

We provide a library for the Proximity11 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 Proximity11 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void proximity11_cfg_setup ( proximity11_cfg_t *cfg );

  • Initialization function.

    PROXIMITY11_RETVAL proximity11_init ( proximity11_t ctx, proximity11_cfg_t cfg );

  • Click Default Configuration function.

    void proximity11_default_cfg ( proximity11_t *ctx );

Example key functions :

  • This function reads proximity values from the desired registers.

    uint8_t proximity11_get ( proximity11_t ctx, uint8_t register_address, uint8_t output_buffer, uint8_t n_bytes );

  • This function updates data used to calculate Lux. This function should be called if changing als measurement time and als gain.

    void proximity11_update ( proximity11_t *ctx );

  • This function sets High ALS threshold value

    void proximity11_set_als_threshold_high ( proximity11_t *ctx, uint16_t threshold_value );

Examples Description

This appication enables usage of the proximity and ambient light sensors

The demo application is composed of two sections :

Application Init

Initializes I2C driver and performs device initialization


void application_init ( void )
{
    log_cfg_t log_cfg;
    proximity11_cfg_t cfg;
    uint8_t init_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.

    proximity11_cfg_setup( &cfg );
    PROXIMITY11_MAP_MIKROBUS( cfg, MIKROBUS_4 );
    proximity11_init( &proximity11, &cfg );

    Delay_ms ( 500 );

    init_status = proximity11_default_cfg( &proximity11 );

    if ( init_status == 1 )
    {
        log_printf( &logger, "> app init fail\r\n" );
        while( 1 );
    }
    else if ( init_status == 0 )
    {
        log_printf( &logger, "> app init done\r\n" );
    }
}

Application Task

Gets ALS and PS values and logs those values


void application_task ( void )
{
    //  Task implementation

    uint16_t ps_value;
    float als_value;

    proximity11_get_ps_als_values( &proximity11, &ps_value, &als_value );

    log_printf( &logger, "PS  : %ld [count]\r\n", ps_value );
    log_printf( &logger, "ALS : %.2f [Lx]\r\n\r\n", als_value );

    Delay_ms ( 500 );

}

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.Proximity11

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.

Accel 22 Click is a compact add-on board that contains an acceleration sensor. This board features the ADXL367, an ultra-low-power, high-performance three-axis accelerometer from Analog Devices. The ADXL367 allows selectable full-scale acceleration measurements in ranges of ±2g, ±4g, and ±8g in three axes, with a resolution of 0.25 mg/LSB on the ±2g range, alongside a configurable host interface that supports both SPI and I2C serial communication. This device combines a 3-axis MEMS accelerometer, a temperature sensor, and a 14-bit analog-to-digital converter (ADC) to synchronize an external analog signal conversion.

LED Driver 4 Click

0

LED Driver 4 Click is a form of a high-efficiency boost converter that is ideally suited for driving an array of white LEDs. The driver has the ability to dim the connected LED array, without producing any noise on the output. The Click board is capable of driving a LED array with up to 26V, providing a constant current to the LED segments.
