Proximity Click

Proximity Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

Measures proximity data and ambient light.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Proximity

Example Key Functions

• proximity_cfg_setup Config Object Initialization function.

void proximity_cfg_setup ( proximity_cfg_t *cfg );

• proximity_init Initialization function.

err_t proximity_init ( proximity_t *ctx, proximity_cfg_t *cfg );

• proximity_default_cfg Click Default Configuration function.

void proximity_default_cfg ( proximity_t *ctx );

• proximity_write_data Functions for write data.

void proximity_write_data ( proximity_t *ctx, uint8_t w_addr, uint8_t* wr_data, uint8_t n_len );

• proximity_read_prox_data Functions for reads Proximity data.

uint16_t proximity_read_prox_data ( proximity_t *ctx );

• proximity_read_ambient_light Functions for reads Ambient light.

uint16_t proximity_read_ambient_light ( proximity_t *ctx );

Application Init

Initialization driver init and sets chip on the default mode

void application_init ( void )
{
    log_cfg_t log_cfg;
    proximity_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.

    proximity_cfg_setup( &cfg );
    PROXIMITY_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    proximity_init( &proximity, &cfg );
    proximity_set_default_mode( &proximity );
}

Application Task

Reads Proximity data and Ambient light data and logs data to USBUART every 500 ms.

void application_task ( void )
{
    //  Task implementation.

    proximity_ambi_value = proximity_read_ambient_light( &proximity );
    proximity_proxi_value = proximity_read_prox_data( &proximity );

    log_printf( &logger, "Proximity:   %u\r\n", proximity_proxi_value);
    log_printf( &logger, " Ambient:   %u LUX\r\n ", proximity_ambi_value);

    Delay_ms ( 500 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
