Excelon-Ultra Click

Excelon-Ultra 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 : Luka Filipovic
• Date : Jun 2021.
• Type : SPI type

Software Support

Example Description

This example is showcase of device and it's library abillity. In this example is shown device ID, ability to manipulate with memory. After default configuration device IDs are logged. After that application Writes data to memory, reads data from memory, clears data from memory and checks if data is cleard by reading that same memory address.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ExcelonUltra

Example Key Functions

• excelonultra_cfg_setup Config Object Initialization function.

void excelonultra_cfg_setup ( excelonultra_cfg_t *cfg );

• excelonultra_init Initialization function.

err_t excelonultra_init ( excelonultra_t *ctx, excelonultra_cfg_t *cfg );

• excelonultra_default_cfg Click Default Configuration function.

err_t excelonultra_default_cfg ( excelonultra_t *ctx );

• excelonultra_write_data_to_memory Write data starting from specified memory address.

err_t excelonultra_write_data_to_memory 
( excelonultra_t *ctx, uint32_t mem_adr, uint8_t *mem_data, uint32_t mem_data_len );

• excelonultra_read_data_from_memory Read data starting from specified memory address.

err_t excelonultra_read_data_from_memory 
( excelonultra_t *ctx, uint32_t mem_adr, uint8_t *mem_data, uint32_t mem_data_len );

• excelonultra_clear_data_from_memory Clears data starting from specified memory address.

err_t excelonultra_clear_data_from_memory 
( excelonultra_t *ctx, uint32_t mem_adr, uint32_t mem_data_len );

Application Init

Initializes MCU modules for communication used in this application (UART, SPI). Calls default configuration that resets device, reads IDs, and enables writing to memory and sets all RAM memory to be free for conrol.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    excelonultra_cfg_t excelonultra_cfg;  /**< Click config object. */

    /** 
     * 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.
    excelonultra_cfg_setup( &excelonultra_cfg );
    EXCELONULTRA_MAP_MIKROBUS( excelonultra_cfg, MIKROBUS_1 );
    err_t init_flag  = excelonultra_init( &excelonultra, &excelonultra_cfg );
    if ( init_flag == SPI_MASTER_ERROR ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    excelonultra_default_cfg ( &excelonultra );
    
    log_printf( &logger, " > Manufacturer ID: 0x%.4X\r\n", excelonultra.manufacturer_id );
    log_printf( &logger, " > Product ID: 0x%.4X\r\n", excelonultra.product_id );
    log_printf( &logger, " > Density ID: 0x%.2X\r\n", excelonultra.density_id );
    log_printf( &logger, " > Die Rev: 0x%.2X\r\n", excelonultra.die_rev );
    
    log_printf( &logger, " > Unique ID: 0x%.2X%.2X%.2X%.2X%.2X%.2X%.2X%.2X\r\n"

    excelonultra.unique_id[ 4 ], excelonultra.unique_id[ 3 ], excelonultra.unique_id[ 2 ],

    Delay_ms ( 1000 );
    log_info( &logger, " Application Task " );
}

Application Task

Write data to memory, read data from memory. After that clears that memory address, and checks if it's cleared by reading data. On every iteration of the fucntion writing data is changed between "MikroE" and "Excelon-Ultra Click"

void application_task ( void ) 
{
    static uint32_t memory_address = 0x00000055;
    static uint8_t data_selection = 1;
    static uint8_t write_len;
    char to_write[ 50 ] = { 0 };
    char read_from[ 50 ] = { 0 };
    
    if (data_selection)
    {
        strcpy( to_write, MIKROE_DATA );
        data_selection = !data_selection;
    }
    else
    {
        strcpy( to_write, CLICK_DATA );
        data_selection = !data_selection;
    }
    write_len = strlen( to_write );
    
    log_printf( &logger, " > Writing data to memory: %s\r\n", to_write );
    excelonultra_write_data_to_memory( &excelonultra, memory_address, to_write, write_len );
    
    Delay_ms ( 500 );
    
    excelonultra_read_data_from_memory( &excelonultra, memory_address, read_from, write_len );
    log_printf( &logger, " > Read data from memory: %s\r\n", read_from );

    Delay_ms ( 500 );

    log_printf( &logger, " > Clearing data from memory\r\n" );
    excelonultra_clear_data_from_memory( &excelonultra, memory_address, write_len );
    
    Delay_ms ( 500 );
    
    excelonultra_read_data_from_memory( &excelonultra, memory_address, read_from, write_len );
    log_printf( &logger, " > Read data from memory: %s\r\n", read_from );

    log_printf( &logger, "***********************************\r\n" );
    Delay_ms ( 500 );
}

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.
