Step Up click

Step Up Click is a fixed frequency DC-DC step-up (boost) regulator, which can be obtained from any low voltage input - such as NiCd, NiMH or one cell Li-Po/Li-Ion batteries.

Click library

Software Support

We provide a library for the StepUp 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 StepUp Click driver.

Standard key functions :

Example key functions :

Examples Description

This application enables usage of DC-DC step-up (boost) regulator.>

The demo application is composed of two sections :

Application Init

Initializes SPI driver, sets config word, initializes the device, sets and log output value

void application_init ( void )
{
log_cfg_t log_cfg;
out_value = 4095;
// 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.
STEPUP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
stepup_init( &stepup, &cfg );
Delay_ms( 100 );
log_printf( &logger, "> app init done\r\n" );
}

Application Task

Simulates user input via UART terminal, if 'user' enters + or - output value is increased or decreased respectively

void application_task ( void )
{
uint8_t i;
// Task implementation.
for ( i = 0; i < 8; i++ )
{
if ( out_value < 4095 )
{
}
Delay_ms( 250 );
}
for ( i = 0; i < 14; i++ )
{
if ( out_value > 0 )
{
}
Delay_ms( 250 );
}
}

Note

Additional Functions :

stepup_logPercent() - calls 'stepup_getPercent()' function to get output value in expressed as percentage and logs that value.

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.

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.
