Flash 8 click

Flash 8 Click is a compact add-on board representing a highly reliable memory solution. This board features the GD5F2GQ5UEYIGR, a 2Gb high-density non-volatile memory storage solution for embedded systems from GigaDevice Semiconductor. It is based on an industry-standard NAND Flash memory core, representing an attractive alternative to SPI-NOR and standard parallel NAND Flash with advanced features. The GD5F2GQ5UEYIGR also has advanced security features (8K-Byte OTP region), software/hardware write protection, can withstand many write cycles (minimum 100k), and has a data retention period greater than ten years.

Click library

  • Author : Nenad Filipovic
  • Date : May 2021.
  • Type : SPI type

Software Support

We provide a library for the Flash8 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Flash8 Click driver.

Standard key functions :

  • flash8_cfg_setup Config Object Initialization function.
void flash8_cfg_setup ( flash8_cfg_t *cfg );
  • flash8_init Initialization function.
err_t flash8_init ( flash8_t *ctx, flash8_cfg_t *cfg );
  • flash8_default_cfg Click Default Configuration function.
void flash8_default_cfg ( flash8_t *ctx );

Example key functions :

  • flash8_write_memory Flash 8 write memory function.
err_t flash8_write_memory ( flash8_t *ctx, uint32_t row_address, uint16_t column_address, uint8_t *data_in, uint16_t len, uint8_t *feature_status_out );
  • flash8_read_memory Flash 8 read memory function.
err_t flash8_read_memory ( flash8_t *ctx, uint32_t row_address, uint16_t column_address, uint8_t *data_out, uint16_t len, uint8_t *feature_status_out );
  • flash8_read_id Flash 8 read ID function.
err_t flash8_read_id ( flash8_t *ctx, uint8_t *manufacture_id, uint8_t *device_id, uint8_t *organization_id );

Example Description

This library contains API for Flash 8 Click driver. The library using SPI serial interface. The library also includes a function for write and read memory as well as write protection control functions.

The demo application is composed of two sections :

Application Init

Initialization of SPI module and log UART. After driver initialization and default setting, involves disabling write protection and hold, the app writes demo_data string ( mikroE ) starting from the selected row_address of the 123 ( 0x0000007B ) and column_address of the 456 ( 0x01C8 ).

void application_init ( void )

    log_cfg_t log_cfg;        /**< Logger config object. */
    flash8_cfg_t flash8_cfg;  /**< Click config object. */

    /** 
     * 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.

Application Task

This is an example that shows the use of a Flash 8 Click board™. The app reads a data string, which we have previously written to memory, starting from the selected row_address of the 123 ( 0x0000007B ) and column_address of the 456 ( 0x01C8 ). Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{   
    flash8_read_memory( &flash8, 123, 456, &rx_data[ 0 ], 9, &feature_status_out );
    log_printf( &logger, "    Read data : %s", rx_data );
    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms( 2000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Flash8

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.
