Boost 7 click

Boost 7 Click is a compact add-on board that steps up the voltage from its input (supply) to its output (load). This board features the BD8316GWL, a dual DC/DC converter from Rohm Semiconductor. Each converter inside the BD8316GWL is designed with up to 200mA current limit generating well-regulated positive and negative outputs of ±3.3V or ±5V, making the BD8316GWL ideal for various applications. In addition to the possibility of working with both mikroBUS™ power rails, it also provides the opportunity of using an external power supply with a very low voltage of 2.5V.

Click library

  • Author : Stefan Filipovic
  • Date : Sep 2022.
  • Type : GPIO type

Software Support

We provide a library for the Boost 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 Boost 7 Click driver.

Standard key functions :

Example key functions :

  • boost7_enable_out1 This function enables the OUT1 (V-) by setting the STB1 pin to high logic state.
  • boost7_disable_out1 This function disables the OUT1 (V-) by setting the STB1 pin to low logic state.
  • boost7_enable_out2 This function enables the OUT2 (V+) by setting the STB2 pin to high logic state.

Example Description

This example demonstrates the use of Boost 7 click board by controlling the V- and V+ outputs state.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.

void application_init ( void )
{
log_cfg_t log_cfg;
boost7_cfg_t boost7_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
boost7_cfg_setup( &boost7_cfg );
BOOST7_MAP_MIKROBUS( boost7_cfg, MIKROBUS_1 );
if ( DIGITAL_OUT_UNSUPPORTED_PIN == boost7_init( &boost7, &boost7_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Toggles the V- and V+ outputs state every 5 seconds and displays their state on the USB UART.

void application_task ( void )
{
log_printf( &logger, " OUT1 (V-) : ENABLED\r\n" );
log_printf( &logger, " OUT2 (V+) : DISABLED\r\n\n" );
boost7_enable_out1 ( &boost7 );
boost7_disable_out2 ( &boost7 );
Delay_ms( 5000 );
log_printf( &logger, " OUT1 (V-) : DISABLED\r\n" );
log_printf( &logger, " OUT2 (V+) : ENABLED\r\n\n" );
boost7_disable_out1 ( &boost7 );
boost7_enable_out2 ( &boost7 );
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.Boost7

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.
