Nano Power 2 click

Nano Power 2 click is a very low power voltage comparator, aimed at portable and battery-powered applications. It allows detecting a difference of two voltage potentials, applied on two input pins.

Click library

• Author : Petar Suknjaja
• Date : Dec 2019.
• Type : GPIO type

Software Support

We provide a library for the NanoPower2 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 NanoPower2 Click driver.

Standard key functions :

• nanopower2_cfg_setup Config Object Initialization function.

  void nanopower2_cfg_setup ( nanopower2_cfg_t *cfg ); 

• nanopower2_init Initialization function.

  err_t nanopower2_init ( nanopower2_t *ctx, nanopower2_cfg_t *cfg );

Example key functions :

• nanopower2_check_output Function gets output voltage from comparator.

  uint8_t nanopower2_check_output ( nanopower2_t *ctx );

Examples Description

This example logs the comparators output value.

The demo application is composed of two sections :

Application Init

Initializes GPIO driver.

void application_init ( void )
{
      log_cfg_t log_cfg;
    nanopower2_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.
    nanopower2_cfg_setup( &cfg );
    NANOPOWER2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    nanopower2_init( &nanopower2, &cfg );

    log_printf( &logger, "NANO POWER 2 is initialized\r\n" );
    out_check_prev = 2;
}

Application Task

Checks the comparator's output and logs output value on USBUART.

void application_task ( void )
{
    out_check = nanopower2_check_output( &nanopower2 );
    if ( out_check != out_check_prev )
    {
        log_printf( &logger, "OUT is: %d\r\n", ( uint16_t ) out_check );

        out_check_prev = out_check;
    }
}  

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.NanoPower2

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.
