Click library

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

Software Support

We provide a library for the Proximity5 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 Proximity5 Click driver.

Standard key functions :

• Config Object Initialization function.

  void proximity5_cfg_setup ( proximity5_cfg_t *cfg );

• Initialization function.

  PROXIMITY5_RETVAL proximity5_init ( proximity5_t ctx, proximity5_cfg_t cfg );

• Click Default Configuration function.

  void proximity5_default_cfg ( proximity5_t *ctx );

Example key functions :

• Starts the conversion and waits for the interrupt to finish.

• After the interrupt finishes the proximity data from the proximity registers

• is returned to a 3 member uint16_t array.

  void proximity5_get_values ( proximity5_t ctx, uint16_t prox_val );

• Read the ID from the ID register of the sensor.

  uint16_t proximity5_get_id ( proximity5_t *ctx );

• Generic function for reading both high and low register value

• and returns those combined values to a 16bit variable.

  uint16_t proximity5_read_reg ( proximity5_t *ctx, uint8_t addr );

Examples Description

The demo application is composed of two sections :

Application Init

This application enables usage of the proximity and ablient light sensing

void application_init ( void )
{
    log_cfg_t log_cfg;
    proximity5_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.

    proximity5_cfg_setup( &cfg );
    PROXIMITY5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    proximity5_init( &proximity5, &cfg );

    proximity5_default_cfg( &proximity5 );
}

Application Task

The proximity data is read from the sensor and it is printed to the UART.

void application_task ( void )
{
    //  Task implementation.

    uint16_t bff[ 4 ];

    proximity5_get_values( &proximity5, bff );

    log_printf( &logger, "PS1 %d  ", bff[ 0 ] );

    log_printf( &logger, "PS2 %d  ", bff[ 1 ] );

    log_printf( &logger, "PS3 %d \r\n\r\n", bff[ 2 ] );

    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.Proximity5

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.
