Click library

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

Software Support

We provide a library for the Buck2 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 Buck2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void buck2_cfg_setup ( buck2_cfg_t *cfg );

  • Initialization function.

    BUCK2_RETVAL buck2_init ( buck2_t *ctx, buck2_cfg_t *cfg );

  • Click Default Configuration function.

    void buck2_default_cfg ( buck2_t *ctx );

Example key functions :

  • Function settings output voltage

    void buck2_set_output_voltage ( buck2_t *ctx , uint8_t voltage );

  • Function reads state PG pin

    uint8_t buck2_get_power_good ( buck2_t *ctx );

  • Function settings chip mode

    void buck2_set_power_mode ( buck2_t *ctx, uint8_t mode );

Examples Description

The demo application displays output voltage change.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Settings the click in the default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
buck2_cfg_setup( &cfg );
BUCK2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
buck2_init( &buck2, &cfg );
buck2_default_cfg( &buck2 );
}

Application Task

Sets a different range of input voltages every 2 s and checks if it has reached the set output voltage.

void application_task ( void )
{
uint8_t pg_state;
pg_state = buck2_get_power_good( &buck2 );
if ( pg_state != 0 )
{
log_info( &logger, "---- Power good output voltage ----" );
}
Delay_ms( 3000 );
Delay_ms( 3000 );
Delay_ms( 3000 );
Delay_ms( 3000 );
}

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.Buck2

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.
