Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Proximity2 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 Proximity2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void proximity2_cfg_setup ( proximity2_cfg_t *cfg );

  • Initialization function.

    PROXIMITY2_RETVAL proximity2_init ( proximity2_t ctx, proximity2_cfg_t cfg );

  • Click Default Configuration function.

    void proximity2_default_cfg ( proximity2_t *ctx );

Example key functions :

  • Read PROX Data Register function.

    uint8_t proximity2_read_prox ( proximity2_t *ctx );

  • Read ALS Data Registers function.

    uint16_t proximity2_read_als ( proximity2_t *ctx );

Examples Description

This is an example that shows the most important functions that Proximity 2 Click has.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Setting the Click in the default configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;
    proximity2_cfg_t cfg;

    /** 
     * 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.

    proximity2_cfg_setup( &cfg );
    PROXIMITY2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    proximity2_init( &proximity2, &cfg );

    proximity2_default_cfg ( &proximity2 );

    log_info( &logger, "Application Init" );
    Delay_ms ( 1000 );
}

Application Task

Shows the most important proximity and ambient value.


void application_task ( void )
{
    proxi_val =  proximity2_read_prox ( &proximity2 );
    ambient = proximity2_read_als ( &proximity2 );

    log_printf( &logger, " Distance : %d \r\n", (uint16_t)proxi_val );

    log_printf( &logger, " Light    : %d \r\n", ambient );

    log_printf( &logger, "------------------\r\n" );

    Delay_ms ( 300 );
}

Note

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.Proximity2

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.

TempHum 16 Click

0

Temp&Hum 16 Click is a compact add-on board that represents temperature and humidity sensing solutions. This board features the WSEN-HIDS (252.0.0.50001), a MEMS-based capacitive humidity sensor with an integrated ASIC and I2C and SPI serial communication from Würth Elektronik. A silicon-based temperature sensor is also integrated within the same package. ASIC contains the multiplier, operational amplifier, analog-to-digital converter, and other signal conditioning blocks like controller logics and interrupts. It converts the analog signal from humidity and temperature sensing elements into 16-bit digital humidity and temperature values. The 252.0.0.50001 is factory calibrated for both humidity and temperature measurements with no further calibration required. This Click board™ is an ideal solution to be used in various temperature and humidity-related applications.
