FRAM 2 Click

FRAM 2 Click carries a ferroelectric RAM module. Ferroelectric RAM, also known as FRAM, is a non-volatile memory type, with characteristics comparable to much faster DRAM memory modules. It offers much faster alternative to common serial FLASH and EEPROM modules, which use the conventional technologies.

Click library

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

Software Support

We provide a library for the FRAM2 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 FRAM2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void fram2_cfg_setup ( fram2_cfg_t *cfg );

  • Initialization function.

    FRAM2_RETVAL fram2_init ( fram2_t ctx, fram2_cfg_t cfg );

  • Click Default Configuration function.

    void fram2_default_cfg ( fram2_t *ctx );

Example key functions :

  • This function reads content from address and saves it to buffer.

    void fram2_read( fram2_t ctx, uint32_t address, uint8_t buffer, uint8_t count );

  • This function writes content from buffer to address.

    void fram2_write( fram2_t ctx, uint32_t address, uint8_t buffer, uint8_t counter );

  • This function reads content of FRAM status register.

    uint8_t fram2_read_status( fram2_t *ctx );

Examples Description

This example performs write & read operation to certain register.

The demo application is composed of two sections :

Application Init

Initiazlize device and enable write operation.


void application_init ( void )
{
    log_cfg_t log_cfg;
    fram2_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.

    fram2_cfg_setup( &cfg );
    FRAM2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    fram2_init( &fram2, &cfg );
    fram2_default_cfg ( &fram2 );

}

Application Task

Write value 42 to register 0x10 and check if operation was done properly.


void application_task ( void )
{
    log_info( &logger, "Writing value 42 into register 0x10..." );  
    test_addr = 0x0010;  
    fram2_write( &fram2, test_addr, data_to_write, 3 );
    Delay_ms ( 200 );

    log_info( &logger, "Reading from register 0x10..." );
    memset( read_buf, 0, 32 );
    Delay_ms ( 500 );

    fram2_read( &fram2, test_addr, read_buf, 3 );
    log_printf ( &logger, "Read value: %s\r\n\n", read_buf );
    Delay_ms ( 500 );
} 

Note

If user doesn't see declarations of some variables in application_init() and application_task(), they are declared as global in main.c file.

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.FRAM2

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.

Stepper 3 Click

0

Stepper 3 Click is designed to drive unipolar stepper motors, with a supply voltage applied to the common wire. The current flows through the common wire and the motor coil, via the activated current sink driver, to the ground. This Click board™ uses the ULN2003A, a high voltage and current Darlington transistors array IC, as the sink driver. This IC is an ideal solution for this purpose, as it has seven high power Darlington output stages, activated by TTL/CMOS logic level signals, applied to the control pins. This allows driving unipolar stepper motors with up to 30V and 500mA per coil.
