Click library

  • Author : Stefan Filipovic
  • Date : Apr 2024.
  • Type : I2C type

Software Support

We provide a library for the PMIC 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 PMIC Click driver.

Standard key functions :

  • pmic_cfg_setup Config Object Initialization function.

    void pmic_cfg_setup ( pmic_cfg_t *cfg );
  • pmic_init Initialization function.

    err_t pmic_init ( pmic_t *ctx, pmic_cfg_t *cfg );
  • pmic_default_cfg Click Default Configuration function.

    err_t pmic_default_cfg ( pmic_t *ctx );

Example key functions :

  • pmic_get_vbat This function reads the VBAT measurement results in millivolts.

    err_t pmic_get_vbat ( pmic_t *ctx, uint16_t *vbat );
  • pmic_get_vbus This function reads the VBUS measurement results in millivolts.

    err_t pmic_get_vbus ( pmic_t *ctx, uint16_t *vbus );
  • pmic_get_vsys This function reads the VSYS measurement results in millivolts.

    err_t pmic_get_vsys ( pmic_t *ctx, uint16_t *vsys );

Example Description

This example demonstrates the use of PMIC Click board by enabling battery charging and displaying the charging status.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration which enables charging.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    pmic_cfg_t pmic_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.
    pmic_cfg_setup( &pmic_cfg );
    PMIC_MAP_MIKROBUS( pmic_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == pmic_init( &pmic, &pmic_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( PMIC_ERROR == pmic_default_cfg ( &pmic ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

Reads and displays the VBAT, VBUS, and VSYS voltage and the battery charging status on the USB UART approximately once per second.

void application_task ( void )
{
    uint16_t vbat = 0, vbus = 0, vsys = 0;
    if ( PMIC_OK == pmic_get_vbat ( &pmic, &vbat ) )
    {
        log_printf( &logger, " VBAT : %u mV\r\n", vbat );
    }
    if ( PMIC_OK == pmic_get_vbus ( &pmic, &vbus ) )
    {
        log_printf( &logger, " VBUS : %u mV\r\n", vbus );
    }
    if ( PMIC_OK == pmic_get_vsys ( &pmic, &vsys ) )
    {
        log_printf( &logger, " VSYS : %u mV\r\n\n", vsys );
    }
    pmic_display_charger_status ( &pmic );
    Delay_ms ( 1000 );
}

Note

A charged battery or a USB at VBUS must be connected to communicate with the Click board.

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.PMIC

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.

Solar Energy 2 Click

0

Solar Energy 2 Click is a compact add-on board that can recharge a battery by harvesting the solar power of the Sun or by other means. This board features the EM8500, a power management controller with an energy harvesting interface from EM Microelectronic. The controller is specifically designed for efficient harvesting over various DC sources such as photovoltaic (solar) or thermal electric generators (TEG). It can recharge the connected LiPo battery or supercapacitor (or even a conventional capacitor). In addition, the EM8500 can use the same battery as a power source for powering the connected system.
