Click library

  • Author : Katarina Perendic
  • Date : nov 2019.
  • Type : GPIO type

Software Support

We provide a library for the Buck3 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 Buck3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void buck3_cfg_setup ( buck3_cfg_t *cfg );

  • Initialization function.

    BUCK3_RETVAL buck3_init ( buck3_t ctx, buck3_cfg_t cfg );

  • Click Default Configuration function.

    void buck3_default_cfg ( buck3_t *ctx );

Example key functions :

  • Function for setting device mode

    void buck3_set_device_state ( buck3_t *ctx, uint8_t state );

  • Function reads state of PGD pin

    uint8_t buck3_get_power_good ( buck3_t *ctx );

Examples Description

This example demonstrates the use of Buck 3 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and configures the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    buck3_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.

    buck3_cfg_setup( &cfg );
    BUCK3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    buck3_init( &buck3, &cfg );

    buck3_default_cfg( &buck3 );
    log_info( &logger, "---- Buck 3 is activated ----" );
    Delay_1sec( );
}

Application Task

Checks the PGD pin state which signalize the undervoltage or overvoltage fault or the thermal shutdown condition. If there's any of the above faults detected it logs a desired message on USB UART.

void application_task ( void )
{
    if ( !buck3_get_power_good( &buck3 ) )
    {
        log_info ( &logger, "---- Overvoltage or thermal shutdown detected ----" );
    }
    Delay_1sec( );
}

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.Buck3

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.

EEG Click

0

EEG Click is a Click board™ that allows monitoring of brain activity. Although not suitable for clinical examination, it is quite sufficient to allow some insight into brain activity. EEG Click is equipped with a high-sensitivity circuit which amplifies faint electrical signals from the brain, allowing them to be sampled by a host MCU.
