Click library

  • Author : Nenad Filipovic
  • Date : Dec 2023.
  • Type : SPI type

Software Support

We provide a library for the Flash 12 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 Flash 12 Click driver.

Standard key functions :

Example key functions :

  • flash12_memory_write This function writes a desired number of data bytes starting to the selected memory address by using SPI serial interface.
    err_t flash12_memory_write ( flash12_t *ctx, uint32_t mem_addr, uint8_t *data_in, uint32_t len );
  • flash12_memory_read This function reads a desired number of data bytes starting from the selected memory address by using SPI serial interface.
    err_t flash12_memory_read ( flash12_t *ctx, uint32_t mem_addr, uint8_t *data_out, uint32_t len );
  • flash12_erase_memory This function erases the selected amount of memory which contains the selected address.
    err_t flash12_erase_memory ( flash12_t *ctx, uint8_t erase_cmd, uint32_t mem_addr );

Example Description

This example demonstrates the use of Flash 12 click board by writing specified data to the memory and reading it back.

The demo application is composed of two sections :

Application Init

The initialization of SPI module and log UART. After driver initialization, the app sets the default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
flash12_cfg_t flash12_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
flash12_cfg_setup( &flash12_cfg );
FLASH12_MAP_MIKROBUS( flash12_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == flash12_init( &flash12, &flash12_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( FLASH12_ERROR == flash12_default_cfg ( &flash12 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task\r\n" );
}

Application Task

The demo application writes writes a desired number of bytes to the memory and then verifies if it is written correctly by reading from the same memory location and displaying the memory content. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
uint8_t data_buf[ 128 ] = { 0 };
log_printf( &logger, " Memory address: 0x%.6LX\r\n", ( uint32_t ) STARTING_ADDRESS );
{
log_printf( &logger, " Erase memory block (4KB)\r\n" );
}
memcpy( data_buf, DEMO_TEXT_MESSAGE_1, strlen( DEMO_TEXT_MESSAGE_1 ) );
data_buf,
sizeof( data_buf ) ) )
{
log_printf( &logger, " Write data: %s\r\n", data_buf );
Delay_ms( 100 );
}
memset( data_buf, 0, sizeof( data_buf ) );
data_buf,
sizeof( data_buf ) ) )
{
log_printf( &logger, " Read data: %s\r\n\n", data_buf );
Delay_ms( 3000 );
}
log_printf( &logger, " Memory address: 0x%.6LX\r\n", ( uint32_t ) STARTING_ADDRESS );
{
log_printf( &logger, " Erase memory block (4KB)\r\n" );
}
memcpy( data_buf, DEMO_TEXT_MESSAGE_2, strlen( DEMO_TEXT_MESSAGE_2 ) );
data_buf, sizeof( data_buf ) ) )
{
log_printf( &logger, " Write data: %s\r\n", data_buf );
Delay_ms( 100 );
}
memset( data_buf, 0, sizeof ( data_buf ) );
data_buf, sizeof ( data_buf ) ) )
{
log_printf( &logger, " Read data: %s\r\n\n", data_buf );
Delay_ms( 3000 );
}
}

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.Flash12

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. UART terminal is available in all MikroElektronika compilers.
