Click library

  • Author : Aleksandra Cvjeticanin
  • Date : Mar 2022.
  • Type : One Wire type

Software Support

We provide a library for the Thumbwheel 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 Thumbwheel Click driver.

Standard key functions :

  • thumbwheel_cfg_setup Config Object Initialization function.

    void thumbwheel_cfg_setup ( thumbwheel_cfg_t *cfg );
  • thumbwheel_init Initialization function.

    err_t thumbwheel_init ( thumbwheel_t *ctx, thumbwheel_cfg_t *cfg );

Example key functions :

  • thumbwheel_get_position This function gets the position of the rotary sprocket.
    err_t thumbwheel_get_position ( thumbwheel_t *ctx, uint8_t *position ); 

Example Description

This example demonstrates the use of Thumbwheel Click board by displaying the exact position of the rotary sprocket.

The demo application is composed of two sections :

Application Init

Initializes the driver and checks the communication.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    thumbwheel_cfg_t thumbwheel_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.
    thumbwheel_cfg_setup( &thumbwheel_cfg );
    THUMBWHEEL_MAP_MIKROBUS( thumbwheel_cfg, MIKROBUS_1 );
    if ( ONE_WIRE_ERROR == thumbwheel_init( &thumbwheel, &thumbwheel_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( THUMBWHEEL_ERROR == thumbwheel_check_communication ( &thumbwheel ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

Demonstrates the usage of thumbwheel_get_position function which gives the exact position of the rotary sprocket. The position will be displayed on the UART Terminal.

void application_task ( void ) 
{
    static uint8_t old_position = 0xFF;
    uint8_t position; 

    if ( ( THUMBWHEEL_OK == thumbwheel_get_position ( &thumbwheel, &position ) ) && 
         ( old_position != position ) )
    {
        log_printf( &logger, " Position: %u \r\n\n", ( uint16_t ) position );
        old_position = position; 
    }
    Delay_ms ( 100 );
}

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.Thumbwheel

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.

Heart Rate 11 Click

0

Heart Rate 11 Click is a compact add-on board suitable for heart rate monitoring applications. This board features the OB1203, a multi-channel light sensor (LS/CS), a proximity sensor (PS), and a photoplethysmography sensor (PPG) from Renesas. It can be configured as an ambient light sensor to measure ambient light similar to the human eye experience or as an RGB color sensor. The OB1203 establishes communication to and from the module entirely through a standard I2C compatible interface and has a fully integrated biosensor for reflective photoplethysmography.
