Boost 2 click

BOOST 2 click is a DC-DC step-up (boost) regulator that has a fixed 5V output, which can be obtained from any low voltage input - such as NiCd, NiMH or one cell Li-Po/Li-Ion batteries.

Click library

• Author : MikroE Team
• Date : jan 2020.
• Type : GPIO type

Software Support

We provide a library for the Boost2 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 Boost2 Click driver.

Standard key functions :

• Config Object Initialization function.

void boost2_cfg_setup ( boost2_cfg_t *cfg );

• Initialization function.

BOOST2_RETVAL boost2_init ( boost2_t *ctx, boost2_cfg_t *cfg );

Example key functions :

• Set enable pin.

void boost2_set_en_pin ( boost2_t *ctx, uint8_t new_state );

• Get PG pin state.

uint8_t boost2_get_pg_pin ( boost2_t *ctx );

Examples Description

This application features very high efficiency, low noise and anti-ringing voltage output.

The demo application is composed of two sections :

Application Init

Initializes click driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    boost2_cfg_t cfg;

    /** 
     * 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.

    boost2_cfg_setup( &cfg );
    BOOST2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    boost2_init( &boost2, &cfg );
}
  

Application Task

Demonstrates the use of the click drivers function. It shows how to enable or disable click operation, and how to check if supplied voltage is good.

void application_task ( void )
{
    log_printf( &logger, "Enabling click operation... \r\n" );
    boost2_set_en_pin( &boost2, 1 );
    Delay_ms(3000);
    
    log_printf( &logger, "Checking output voltage... \r\n" );
    Delay_ms(500);
    if ( boost2_get_pg_pin( &boost2 ))
    {
        log_printf( &logger, "Output voltage good. \r\n" );
    }
    else
    {
        log_printf( &logger, "Output voltage incorrect. \r\n" );
    }
    Delay_ms(3000);
    
    log_printf( &logger, "Disabling click operation... \r\n" );
    boost2_set_en_pin( &boost2, 0 );
    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.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Boost2

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.
