  • Type : I2C type

Software Support

We provide a library for the Smart Buck 4 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 Smart Buck 4 Click driver.

Example Description

This example demonstrates the use of the Smart Buck 4 Click board.

This driver provides functions for device configurations and for the setting of the output voltage.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART.

After initializing the driver, the default configuration is executed and the outputs are turned off.

void application_init ( void )
{
log_cfg_t log_cfg;
smartbuck4_cfg_t smartbuck4_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
smartbuck4_cfg_setup( &smartbuck4_cfg );
SMARTBUCK4_MAP_MIKROBUS( smartbuck4_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == smartbuck4_init( &smartbuck4, &smartbuck4_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( SMARTBUCK4_ERROR == smartbuck4_default_cfg ( &smartbuck4 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Changes the output voltage every 5 seconds, starting from 0.6 V to 3.3V/3.7V

depending on the input voltage.

void application_task ( void )
{
{
err_t error_flag = smartbuck4_send_command( &smartbuck4, SMARTBUCK4_REG_R600B_PROGRAM |
if ( SMARTBUCK4_ERROR == error_flag )
{
log_error( &logger, " Transmission error occurred." );
for ( ; ; );
}

}

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.SmartBuck4

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.
