Boost 11 click

Boost 11 Click is a compact add-on board that boosts low input voltages to a stable output. This board features the XCL105B331H2-G, a synchronous step-up DC/DC converter from TOREX Semi. It operates from an input voltage as low as 0.9V, ideal for devices using single Alkaline or Nickel-metal hydride batteries, with an output fixed at 3.3V. It features an EN pin for easy start-up and standby mode and supports both 3.3V and 5V logic levels. This versatility makes Boost 11 Click suitable for industrial equipment, IoT devices, wearables, and applications prioritizing battery life.

Click library

• Author : Nenad Filipovic
• Date : Jan 2024.
• Type : ADC type

Software Support

We provide a library for the Boost 11 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 11 Click driver.

Standard key functions :

• boost11_cfg_setup Config Object Initialization function.

  void boost11_cfg_setup ( boost11_cfg_t *cfg );

• boost11_init Initialization function.

  err_t boost11_init ( boost11_t *ctx, boost11_cfg_t *cfg );

Example key functions :

• boost11_active_mode This function activates the boost operating mode.

  void boost11_active_mode ( boost11_t *ctx );

• boost11_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.

  err_t boost11_read_an_pin_voltage ( boost11_t *ctx, float *data_out );

Example Description

This example demonstrates the use of Boost 11 click board by controlling the output state.

The demo application is composed of two sections :

Application Init

Initialization of GPIO module, log UART, and activate the boost operating mode.

void application_init ( void )
{
    log_cfg_t log_cfg;          /**< Logger config object. */
    boost11_cfg_t boost11_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    boost11_cfg_setup( &boost11_cfg );
    BOOST11_MAP_MIKROBUS( boost11_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == boost11_init( &boost11, &boost11_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    boost11_active_mode( &boost11 );
    Delay_ms ( 100 );

    log_info( &logger, " Application Task " );
}

Application Task

The demo application reads measurements of the output voltage level [V]. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    float voltage = 0;
    if ( BOOST11_OK == boost11_read_an_pin_voltage ( &boost11, &voltage ) ) 
    {
        log_printf( &logger, " Output Voltage : %.3f[V]\r\n\n", voltage );
        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.Boost11

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.
