Semper Flash Click

Semper Flash 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 : May 2020.
  • Type : SPI type

Software Support

Example Description

This example showcases how to initialize and use the Semper Flash Click. The Click is a 512 Mbit SPI Flash memory module. Data can be stored in and read from the flash memory. There's also the option of erasing it's contents. Here's how to do it.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.SemperFlash

Example Key Functions

  • semperflash_cfg_setup Config Object Initialization function.
void semperflash_cfg_setup ( semperflash_cfg_t *cfg );
  • semperflash_init Initialization function.
err_t semperflash_init ( semperflash_t *ctx, semperflash_cfg_t *cfg );
  • semperflash_default_cfg Click Default Configuration function.
void semperflash_default_cfg ( semperflash_t *ctx );
  • semperflash_write_memory This function writes data to the flash memory.
uint8_t semperflash_write_memory  ( semperflash_t *ctx, uint32_t addr, uint8_t *data_buf, uint16_t buf_size  );
  • semperflash_read_memory This function reads data from the flash memory.
uint8_t semperflash_read_memory  ( semperflash_t *ctx, uint32_t addr, uint8_t *data_buf, uint16_t buf_size  );
  • semperflash_erase_memory This function erases data from the flash memory.
void semperflash_erase_memory ( semperflash_t *ctx, uint32_t addr );

Application Init

This function initializes and configures the Click and logger modules. Additional con- figuring is done in the default_cfg(...) function. The device ID should appear in the UART console if the setup finishes successfully.

void application_init ( void )
{
    log_cfg_t log_cfg;
    semperflash_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 ----" );
    Delay_ms ( 100 );

    //  Click initialization.

    semperflash_cfg_setup( &cfg );
    SEMPERFLASH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    semperflash_init( &semperflash, &cfg );
    semperflash_default_cfg( &semperflash );
    id_check( );
    Delay_ms ( 500 );
}

Application Task

This function first erases the contents of the flash memory and then writes, reads and prints two strings in the UART console. It does so every 2 seconds.

void application_task ( void )
{
    char write_data_com[ 7 ] = "MikroE";
    char write_data_clk[ 13 ] = "Semper Flash";
    char read_buf_data[ 13 ] = { 0 };

    semperflash_send_cmd( &semperflash, SEMPERFLASH_WRITE_ENABLE );
    semperflash_erase_memory( &semperflash, ADRESS_MEMORY );
    
    if ( COMPANY_FLAG == txt_flag )
    {
       semperflash_send_cmd( &semperflash, SEMPERFLASH_WRITE_ENABLE );
       error_handler( semperflash_write_memory( &semperflash, ADRESS_MEMORY, write_data_com, 6 ) );
       error_handler( semperflash_read_memory( &semperflash, ADRESS_MEMORY, read_buf_data, 6 ) );
       log_printf( &logger, "%s\r\n", read_buf_data );
       txt_flag = CLICK_FLAG;       
    }
    else if ( CLICK_FLAG == txt_flag )
    {
       semperflash_send_cmd( &semperflash, SEMPERFLASH_WRITE_ENABLE );
       error_handler( semperflash_write_memory( &semperflash, ADRESS_MEMORY, write_data_clk, 12 ) );
       error_handler( semperflash_read_memory( &semperflash, ADRESS_MEMORY, read_buf_data, 12 ) );
       log_printf( &logger, "%s\r\n", read_buf_data );
       txt_flag = COMPANY_FLAG;
    }

    log_printf( &logger, "....................\r\n" );
    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.
