Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : GPIO type

Software Support

We provide a library for the PowerReset 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 PowerReset Click driver.

Standard key functions :

  • Config Object Initialization function.

    void powerreset_cfg_setup ( powerreset_cfg_t *cfg );

  • Initialization function.

    POWERRESET_RETVAL powerreset_init ( powerreset_t ctx, powerreset_cfg_t cfg );

Example key functions :

  • Power Check function.

    powerreset_state_t powerreset_get_pwr( powerreset_t *ctx );

  • Reset Check function.

    powerreset_state_t powerreset_get_rst( powerreset_t *ctx );

Examples Description

Reads PWR and RST pin states and performs a control of the timer counter depending on the pressed button.

The demo application is composed of two sections :

Application Init

Initializes device and logger module, prints Initialization done message.


void application_init ( void )
{
    log_cfg_t log_cfg;
    powerreset_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.

    powerreset_cfg_setup( &cfg );
    POWERRESET_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    powerreset_init( &powerreset, &cfg );

    Delay_ms ( 100 );

    log_printf( &logger, "** Touch Button initialization done **\r\n");
    log_printf( &logger, "**************************************\r\n");
}

Application Task

Checks the states of the PWR and RST pins and logs every change.


void application_task ( void )
{
    new_pwr_state = powerreset_get_pwr( &powerreset );
    new_rst_state = powerreset_get_rst( &powerreset );

    if ( new_pwr_state != pwr_state )
    {
        if ( new_pwr_state == POWERRESET_ACTIVE )
        {
            log_printf( &logger, "POWER ON\r\n" );
            Delay_ms ( 100 );
        }
        else if ( new_pwr_state == POWERRESET_INACTIVE )
        {
            log_printf( &logger, "POWER OFF\r\n" );
            Delay_ms ( 100 );
        }
        pwr_state = new_pwr_state;
    }

    if ( new_rst_state != rst_state )
    {
        if ( new_rst_state == POWERRESET_ACTIVE )
        {
            log_printf( &logger, "Reset occured!\r\n" );
            Delay_ms ( 100 );
        }
        rst_state = new_rst_state;
    }
}

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.PowerReset

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.
