Boost-INV click

Boost-INV click is a very useful DC/DC voltage converter device, as can output both positive and negative voltage, boosted up to 12.78V and -13.95, from a single fixed voltage input.

Click library

Software Support

We provide a library for the BoostInv 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 BoostInv Click driver.

Standard key functions :

Example key functions :

Examples Description

Changes the positive and negative output voltage. Input Voltage 3.3V. Positive output voltage goes from 3200mV, 7750mV, 12000mV and 7750mV. Negative output voltage goes from -1450mV, -6700mV, -11050mV and -6700mV.

The demo application is composed of two sections :

Application Init

Initializes I2C module and sets EN ( RST ) pin as output.

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.
BOOSTINV_MAP_MIKROBUS( cfg, MIKROBUS_1 );
boostinv_init( &boostinv, &cfg );
boostinv_default_cfg ( &boostinv );
log_printf( &logger, " Boost INV Click\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 100 );
}

Application Task

Changes the positive and negative output voltage every 5 sec.

void application_task ( void )
{
// Task implementation.
// Sets Positive output voltage
log_printf( &logger, " Positive output voltage \r\n" );
log_printf( &logger, "- - - - - - - - - - - - -\r\n" );
log_printf( &logger, " 3200 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
log_printf( &logger, " 7750 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
log_printf( &logger, " 12000 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
log_printf( &logger, " 7750 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
// Sets Negative output voltage
log_printf( &logger, " Negative output voltage \r\n" );
log_printf( &logger, "- - - - - - - - - - - - -\r\n" );
log_printf( &logger, " -1450 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
log_printf( &logger, " - 6700 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
log_printf( &logger, " - 11050 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
log_printf( &logger, " - 6700 mV\r\n" );
log_printf( &logger, "-------------------------\r\n" );
Delay_ms( 5000 );
}

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.
