Click library

  • Author : Stefan Ilic
  • Date : Nov 2023.
  • Type : I2C type

Software Support

We provide a library for the PCR 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 PCR Click driver.

Standard key functions :

  • pcr_cfg_setup Config Object Initialization function.

    void pcr_cfg_setup ( pcr_cfg_t *cfg );
  • pcr_init Initialization function.

    err_t pcr_init ( pcr_t *ctx, pcr_cfg_t *cfg );
  • pcr_default_cfg Click Default Configuration function.

    err_t pcr_default_cfg ( pcr_t *ctx );

Example key functions :

  • pcr_write_reg PCR register writing function.

    err_t pcr_write_reg ( pcr_t *ctx, uint16_t reg, uint32_t data_in );
  • pcr_check_if_busy PCR check if device is busy function.

    err_t pcr_check_if_busy ( pcr_t *ctx );
  • pcr_get_distance PCR read distance function.

    err_t pcr_get_distance ( pcr_t *ctx, uint32_t *distance_data );

Example Description

This example demonstrates the use of PCR Click board by reading distance between Click board and object.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger and performs the Click default configuration.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    pcr_cfg_t pcr_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.
    pcr_cfg_setup( &pcr_cfg );
    PCR_MAP_MIKROBUS( pcr_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == pcr_init( &pcr, &pcr_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( PCR_ERROR == pcr_default_cfg ( &pcr ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

Reading distance between Click board and object every 2 seconds and logging it on UART terminal.

void application_task ( void ) 
{
    uint32_t distance_data = 0;

    pcr_get_distance ( &pcr, &distance_data );
    log_printf( &logger, " Distance: %lu mm \r\n", distance_data );
    Delay_ms ( 1000 );
    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.PCR

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.

Line Follower click

1

Line Follower click carries an array of five QRE1113 miniature reflective object sensors. For communicating with the target MCU, the individual sensors have their own separate digital outputs, each one routed through a single mikroBUSâ„¢ pin. Line Follower click is designed to use either a 3.3V or a 5V power supply.
