Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

We provide a library for the Mcp73213 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 Mcp73213 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void mcp73213_cfg_setup ( mcp73213_cfg_t *cfg );

  • Initialization function.

    MCP73213_RETVAL mcp73213_init ( mcp73213_t ctx, mcp73213_cfg_t cfg );

Example key functions :

  • Set values for output current function

    void mcp73213_set_current_output ( mcp73213_t *ctx, uint8_t out_data );

  • Get the status register data function

    uint8_t mcp73213_get_status ( mcp73213_t *ctx );

  • Convert ADC value to volatage

    float mcp73213_convert_output ( uint8_t value_adc, float v_ref );

Examples Description

This application is polymer battery charge management controller.

The demo application is composed of two sections :

Application Init

Initialization driver enable's - SPI, also write log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    mcp73213_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.

    mcp73213_cfg_setup( &cfg );
    MCP73213_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mcp73213_init( &mcp73213, &cfg );

    log_printf( &logger, "   SPI Driver Init     \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, "---------------------- \r\n" );
    log_printf( &logger, "  Set Current Output   \r\n" );
}

Application Task

This is a example which demonstrates the use of MCP73213 Click board. This example sets the resistance to a given value, thus affecting the output current. Controls output current using internal digital potentiometer. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on usb uart changes for every 3 sec.


void application_task ( void )
{
    log_printf( &logger, "---------------------- \r\n" );
    log_printf( &logger, "   10 kOhm - 130 mA    \r\n" );
    mcp73213_set_current_output( &mcp73213, MCP73213_OUTPUT_130_mA );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, "---------------------- \r\n" );
    log_printf( &logger, "    5 kOhm - 250 mA    \r\n" );
    mcp73213_set_current_output( &mcp73213, MCP73213_OUTPUT_250_mA );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.Mcp73213

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.
