Click library

  • Author : Katarina Perendic
  • Date : okt 2019.
  • Type : I2C type

Software Support

We provide a library for the Joystick2 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 Joystick2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void joystick2_cfg_setup ( joystick2_cfg_t *cfg );

  • Initialization function.

    JOYSTICK2_RETVAL joystick2_init ( joystick2_t ctx, joystick2_cfg_t cfg );

  • Click Default Configuration function.

    void joystick2_default_cfg ( joystick2_t *ctx );

Example key functions :

  • Functions for configuration joystick

    void joystick2_set_cfg_register ( joystick2_t *ctx, uint8_t cfg_data );

  • Functions for get Joystick position

    uint8_t joystick2_get_position ( joystick2_t *ctx );

  • Functions for read interrupt state

    uint8_t joystick2_get_interrupt_state ( joystick2_t *ctx );

Examples Description

The demo application shows reading the joistick position ..

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Reset device and settings the Click in the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    joystick2_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.

    joystick2_cfg_setup( &cfg );
    JOYSTICK2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    joystick2_init( &joystick2, &cfg );

    joystick2_reset( &joystick2 );
    joystick2_default_cfg( &joystick2 );
    log_info( &logger, "---- JOYSTICK START ----" );
}

Application Task

It reads the position of the joystick, if it detects that the joystick has moved from the zero position, it prints a message about the current position.

void application_task ( void )
{
    uint8_t joystick_pos;

    //  Task implementation.

    joystick_pos = joystick2_get_position( &joystick2 );

    switch ( joystick_pos )
    {
        case JOYSTICK2_BUTTON_ACTIVE:
        {
            log_info( &logger, "--- Button is pressed!!! ---" );
            Delay_ms ( 300 );
            break;
        }
        case JOYSTICK2_POSITION_RIGHT:
        {
            log_info( &logger, "--- Joystick position [RIGHT] ---" );
            Delay_ms ( 300 );
            break;
        }
        case JOYSTICK2_POSITION_LEFT:
        {
            log_info( &logger, "--- Joystick position [LEFT] ---" );
            Delay_ms ( 300 );
            break;
        }
        case JOYSTICK2_POSITION_UP:
        {
            log_info( &logger, "--- Joystick position [UP] ---" );
            Delay_ms ( 300 );
            break;
        }
        case JOYSTICK2_POSITION_DOWN:
        {
            log_info( &logger, "--- Joystick position [DOWN] ---" );
            Delay_ms ( 300 );
            break;
        }
    }
}

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.Joystick2

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.
