EEPROM 2 Click

EEPROM 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.

Example Description

This example demonstrates the process of writing and reading of data from EEPROM.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Eeprom2

Example Key Functions

• eeprom2_cfg_setup Config Object Initialization function.

void eeprom2_cfg_setup ( eeprom2_cfg_t *cfg ); 

• eeprom2_init Initialization function.

err_t eeprom2_init ( eeprom2_t *ctx, eeprom2_cfg_t *cfg );

• eeprom2_write This function writes a single byte of data to the given memory address.

void eeprom2_write ( eeprom2_t *ctx, uint32_t memory_address, uint8_t value );

• eeprom2_write_bytes This function writes bytes of data to the given memory address.

void eeprom2_write_bytes( eeprom2_t *ctx, uint32_t memory_address, uint8_t *value, uint8_t count );

• eeprom2_read_bytes This function reads bytes from the given memory address.

void eeprom2_read_bytes( eeprom2_t *ctx, uint32_t memory_address, uint8_t *value, uint8_t count );

Application Init

Initializes EEPROM 2 driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    eeprom2_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.
    eeprom2_cfg_setup( &cfg );
    EEPROM2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    eeprom2_init( &eeprom2, &cfg );
}

Application Task

Writing data to EEPROM and then reading that data and writing it via UART.

void application_task ( void )
{
    eeprom2_write_bytes ( &eeprom2, 0x01, text, 6 );
    log_printf ( &logger, "Writing Mikroe to EEPROM 2 Click\r\n" );
    Delay_ms ( 1000 );
    eeprom2_read_bytes ( &eeprom2, 0x01 , mem_value, 6 );
    log_printf ( &logger, "Data read: %s\r\n", mem_value );
    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.
