Click library

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

Software Support

We provide a library for the Flash4 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 Flash4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void flash4_cfg_setup ( flash4_cfg_t *cfg );

  • Initialization function.

    FLASH4_RETVAL flash4_init ( flash4_t ctx, flash4_cfg_t cfg );

  • Generic transfer function.

    void flash4_generic_transfer ( flash4_t ctx, uint8_t wr_buf, uint16_t wr_len, uint8_t *rd_buf, uint16_t rd_len );

Example key functions :

  • Function for read Manufacturer ID.

    void flash4_read_manufacturer_id ( flash4_t ctx, uint8_t device_id );

  • Write command function.

    void flash4_write_command ( flash4_t *ctx, uint8_t cmd );

  • Read Flash with 4 byte address function.

    void flash4_read_flash_4 ( flash4_t ctx, uint8_t out_data, uint32_t addr, uint8_t n_data );

Examples Description

This example demonstrates the use of Flash 4 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables the Click board, then checks the communication by reading the device and manufacturer IDs.


void application_init ( void )
{
    log_cfg_t log_cfg;
    flash4_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.

    flash4_cfg_setup( &cfg );
    FLASH4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    flash4_init( &flash4, &cfg );

    flash4_reset( &flash4 );

    Delay_ms ( 1000 );

    flash4_read_manufacturer_id( &flash4, device_id );

    if ( device_id[ 0 ] != FLASH4_MANUFACTURER_ID || device_id[ 1 ] != FLASH4_DEVICE_ID )
    {
        log_error( &logger, "WRONG ID READ" );
        log_printf( &logger, "Please restart your system.\r\n" );
        for( ; ; );
    }
    Delay_ms ( 1000 );
}

Application Task

Erases sector memory starting from 0x00001234 address, then writes a desired message to the same address. After that, verifies if the message is written correctly by reading it back and displaying it to the USB UART every 5 seconds.


void application_task ( void )
{
    char read_buffer[ 10 ] = { 0 };

    flash4_write_command( &flash4, FLASH4_CMD_WRITE_ENABLE_WREN );
    log_printf( &logger, "--- Erase chip --START-- \r\n" );
    flash4_sector_erase_4( &flash4,  0x00001234 );
    while ( flash4_check_wip( &flash4 ) );
    log_printf( &logger, "--- Erase chip --DONE-- \r\n" );

    flash4_write_command( &flash4, FLASH4_CMD_WRITE_ENABLE_WREN );
    flash4_page_program_4( &flash4, DEMO_MESSAGE, 0x00001234, strlen( DEMO_MESSAGE ) );
    while ( flash4_check_wip( &flash4 ) );
    Delay_100ms( );

    flash4_read_flash_4( &flash4, read_buffer, 0x00001234, strlen( DEMO_MESSAGE ) );
    while ( flash4_check_wip( &flash4 ) );

    log_printf( &logger, "--- Read buffer : %s\r\n", read_buffer );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.Flash4

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.
