Fram Click

Fram 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 : Dec 2019.
• Type : SPI type

Software Support

Example Description

This app writing data to Click memory.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Fram

Example Key Functions

• fram_cfg_setup Config Object Initialization function.

void fram_cfg_setup ( fram_cfg_t *cfg );

• fram_init Initialization function.

err_t fram_init ( fram_t *ctx, fram_cfg_t *cfg );

• fram_default_cfg Click Default Configuration function.

void fram_default_cfg ( fram_t *ctx );

• fram_write_enable This function that sends write enable command to the chip.

void fram_write_enable ( fram_t *ctx );

• fram_read This function reads sequential memory locations to buffer.

void fram_read ( fram_t *ctx, uint16_t address, uint8_t *buffer, uint16_t count );

• fram_write This function writes to sequential memory locations from buffer.

void fram_write ( fram_t *ctx, uint16_t address, uint8_t *buffer, uint16_t count );

Application Init

Initialization device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    fram_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 ----\r\n" );

    //  Click initialization.

    fram_cfg_setup( &cfg );
    FRAM_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    fram_init( &fram, &cfg );
    fram_erase_all( &fram );
}

Application Task

Writing data to Click memory and displaying the read data via UART.

void application_task ( void )
{
    char wr_data[ 10 ] = { 'M', 'i', 'k', 'r', 'o', 'E', 13, 10, 0 };
    char rd_data[ 10 ];

    log_printf( &logger, "Writing MikroE to  Fram memory, from address 0x0150: \r\n" );
    fram_write( &fram, 0x0150, &wr_data[ 0 ], 9 );
    log_printf( &logger, "Reading 9 bytes of Fram memory, from address 0x0150: \r\n" );
    fram_read( &fram, 0x0150, &rd_data[ 0 ], 9 );
    log_printf( &logger, "Data read: %c \r\n", rd_data );
    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.
