Software Support

We provide a library for the Step Down 7 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 Step Down 7 Click driver.

Example Description

This library contains API for the Step Down 7 Click driver.

This driver provides the functions to set the output voltage treshold.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART.

After driver initialization, default settings sets output voltage to 1.5 V.

void application_init ( void )
{
log_cfg_t log_cfg;
stepdown7_cfg_t stepdown7_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
stepdown7_cfg_setup( &stepdown7_cfg );
STEPDOWN7_MAP_MIKROBUS( stepdown7_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == stepdown7_init( &stepdown7, &stepdown7_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( STEPDOWN7_ERROR == stepdown7_default_cfg ( &stepdown7 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the Step Down 7 Click boardâ„¢ by changing

output voltage every 5 seconds starting from 1.5 V up to 3.3 V.

void application_task ( void )
{
for ( uint8_t n_cnt = STEPDOWN7_OUTPUT_1V5; n_cnt <= STEPDOWN7_OUTPUT_3V3; n_cnt++ )
{
stepdown7_set_output( &stepdown7, n_cnt );
log_printf( &logger, " Selected output is:" );
print_selected_output_level ( n_cnt );
Delay_ms( 5000 );
}
}

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.StepDown7

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.
