Click library

• Author : Nemanja Medakovic
• Date : Nov 2019.
• Type : SPI type

Software Support

We provide a library for the Charger5 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 Charger 5 Click driver.

Standard key functions :

• Configuration Object Setup function.

  void charger5_cfg_setup( charger5_cfg_t *cfg );

• Click Initialization function.

  charger5_err_t charger5_init( charger5_t ctx, charger5_cfg_t cfg );

• Click Default Configuration function.

  void charger5_default_cfg( charger5_t *ctx );

Example key functions :

• Generic Write function.

  charger5_err_t charger5_generic_write( charger5_t *ctx, uint8_t reg_addr, uint16_t transfer_data );

• Generic Read function.

  uint16_t charger5_generic_read( charger5_t *ctx, uint8_t reg_addr );

• Increment Wiper function.

  charger5_err_t charger5_increment_wiper( charger5_t *ctx, uint8_t reg_addr, uint8_t n_steps );

Examples Description

This example demonstrates the use of the Charger 5 click board.

The demo application is composed of two sections :

Application Init

Initializes peripherals and pins used for the Charger 5 click and prepares the Charger 5 click for properly working.

void application_init( void )
{
    charger5_cfg_t charger5_cfg;
    log_cfg_t console_cfg;

    //  Click initialization.
    charger5_cfg_setup( &charger5_cfg );
    CHARGER5_MAP_MIKROBUS( charger5_cfg, MIKROBUS_1 );
    charger5_init( &charger5, &charger5_cfg );
    charger5_default_cfg( &charger5 );

    /** 
     * 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( console_cfg );
    log_init( &console, &console_cfg );
    log_write( &console, "***  Charger 5 initialization done  ***",
               LOG_FORMAT_LINE );
    log_write( &console, "***************************************",
               LOG_FORMAT_LINE );
}

Application Task

Demonstrates the use of driver functions. It will set charging current to 500 mA, then will increment that value by 10 steps, and after that will decrement it by 5 steps.

void application_task( void )
{
    charger5_generic_write( &charger5, CHARGER5_REG_WIPER0_VOL,
                            CHARGER5_CURRENT_500MA );
    log_write( &console, "Output current is set to 500 mA.",
               LOG_FORMAT_LINE );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    charger5_increment_wiper( &charger5, CHARGER5_REG_WIPER0_VOL,
                              CHARGER5_STEPS_10 );
    log_write( &console, "Output current value is incremented by 10 steps.",
               LOG_FORMAT_LINE );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    charger5_decrement_wiper( &charger5, CHARGER5_REG_WIPER0_VOL,
                              CHARGER5_STEPS_5 );
    log_write( &console, "Output current value is decremented by 5 steps.",
               LOG_FORMAT_LINE );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

Increment/decrement command can only be issued to volatile memory locations.

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.Charger5

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.
