Step Up 2 Click

Step Up 2 Click is a compact add-on board designed to boost the power capabilities of devices. This board features the TPS61299, a synchronous boost converter from Texas Instruments. This component is renowned for its low quiescent current and high efficiency under light-load conditions. The board distinguishes itself with the ability to adjust output voltage via the integrated MAX5419 digital potentiometer, offering precise control through an I2C interface. It supports external voltages from 0.2V to 5.5V, delivering a regulated output range of 1.8V to 5.5V.

Software Support

We provide a library for the Step Up 2 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 Up 2 Click driver.

Example Description

This example demonstrates the use of the Step Up 2 Click board by changing the output voltage.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization, the app executes a default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
stepup2_cfg_t stepup2_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
stepup2_cfg_setup( &stepup2_cfg );
STEPUP2_MAP_MIKROBUS( stepup2_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == stepup2_init( &stepup2, &stepup2_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( STEPUP2_ERROR == stepup2_default_cfg ( &stepup2 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

The demo application changes the output voltage and displays the current voltage output value. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
float vout_table[ 15 ] = { STEPUP2_VOUT_LIST };
for ( stepup2_vout_t vout = STEPUP2_VOUT_5V5; vout <= STEPUP2_VOUT_3V3; vout++ )
{
if ( STEPUP2_OK == stepup2_set_vout( &stepup2, vout ) )
{
log_printf( &logger, " Voltage: %.2f[V]\r\n\n", vout_table[ vout ] );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
}
}

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.StepUp2

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.
