Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Fram Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Fram Click driver.

Standard key functions :

  • Config Object Initialization function.

    void fram_cfg_setup ( fram_cfg_t *cfg );

  • Initialization function.

    FRAM_RETVAL fram_init ( fram_t ctx, fram_cfg_t cfg );

  • Click Default Configuration function.

    void fram_default_cfg ( fram_t *ctx );

Example key functions :

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

    void fram_write_enable ( fram_t *ctx );

  • This function reads sequential memory locations to buffer.

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

  • This function writes to sequential memory locations from buffer.

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

Examples Description

This app writing data to Click memory.

The demo application is composed of two sections :

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 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
