Solar Energy 2 Click

Solar Energy 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

• Author : Nenad Filipovic
• Date : Jan 2023.
• Type : I2C type

Software Support

Example Description

This library contains API for the Solar Energy 2 Click driver. This driver provides functions to configure the power management controller with an energy harvesting interface.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SolarEnergy2

Example Key Functions

• solarenergy2_cfg_setup Config Object Initialization function.

  void solarenergy2_cfg_setup ( solarenergy2_cfg_t *cfg );

• solarenergy2_init Initialization function.

  err_t solarenergy2_init ( solarenergy2_t *ctx, solarenergy2_cfg_t *cfg );

• solarenergy2_default_cfg Click Default Configuration function.

  err_t solarenergy2_default_cfg ( solarenergy2_t *ctx );

• solarenergy2_set_pwr_current_source Solar Energy 2 power source selection function.

  err_t solarenergy2_set_pwr_current_source ( solarenergy2_t *ctx, uint8_t crt_src_sel )

• solarenergy2_config_abs_voltage Solar Energy 2 config absolute voltage function.

  err_t solarenergy2_config_abs_voltage ( solarenergy2_t *ctx, solarenergy2_abs_vtg_v_t abs_vtg );

• solarenergy2_set_mppt_ratio Solar Energy 2 set MPPT ratio function.

  err_t solarenergy2_set_mppt_ratio ( solarenergy2_t *ctx, uint8_t mppt_ratio );

Application Init

Initialization of I2C module and log UART. After driver initialization, the app set default settings.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  
    solarenergy2_cfg_t solarenergy2_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    solarenergy2_cfg_setup( &solarenergy2_cfg );
    SOLARENERGY2_MAP_MIKROBUS( solarenergy2_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == solarenergy2_init( &solarenergy2, &solarenergy2_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( SOLARENERGY2_ERROR == solarenergy2_default_cfg ( &solarenergy2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );    
}

Application Task

This is an example that shows the use of Solar Energy 2 Click board™. The following example will charge the battery if it is below the maximum voltage of the application of 3.40 V, stop charging when the battery is full and monitor additional status and storage element voltage information. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{   
    if ( SOLARENERGY2_OK == solarenergy2_get_status( &solarenergy2, &status ) )
    {
        if  ( SOLARENERGY2_OK == solarenergy2_get_bat_vtg_status( &solarenergy2, &vld_status ) )
        {
            display_status( );    
        }
    }
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
