MCP73213 Click

MCP73213 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 : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

Example Description

This application is polymer battery charge management controller.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Mcp73213

Example Key Functions

  • mcp73213_cfg_setup Config Object Initialization function.
void mcp73213_cfg_setup ( mcp73213_cfg_t *cfg );
  • mcp73213_init Initialization function.
err_t mcp73213_init ( mcp73213_t *ctx, mcp73213_cfg_t *cfg );
  • mcp73213_set_current_output Set values for output current function.
void mcp73213_set_current_output ( mcp73213_t *ctx, uint8_t out_data );
  • mcp73213_get_status Get the status register data function.
uint8_t mcp73213_get_status ( mcp73213_t *ctx );
  • mcp73213_convert_output Convert ADC value to volatage.
float mcp73213_convert_output ( uint8_t value_adc, float v_ref );

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 );
}

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.
