Click library

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

Software Support

We provide a library for the Flash 11 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 11 Click driver.

Standard key functions :

Example key functions :

  • flash11_memory_write Flash 11 memory write function.
    err_t flash11_memory_write ( flash11_t *ctx, uint32_t mem_addr, uint8_t *data_in, uint32_t len );
  • flash11_memory_read Flash 11 memory read function.
    err_t flash11_memory_read ( flash11_t *ctx, uint32_t mem_addr, uint8_t *data_out, uint32_t len );
  • flash11_block_erase Flash 11 block erase function.
    err_t flash11_block_erase ( flash11_t *ctx, uint8_t cmd_block_erase, uint32_t mem_addr );

Example Description

This example demonstrates the use of Flash 11 click board The demo app writes specified data to the memory and reads it back.

The demo application is composed of two sections :

Application Init

The initialization of SPI module, log UART, and additional pins. After the driver init, the app executes a default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
flash11_cfg_t flash11_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
flash11_cfg_setup( &flash11_cfg );
FLASH11_MAP_MIKROBUS( flash11_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == flash11_init( &flash11, &flash11_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( FLASH11_ERROR == flash11_default_cfg ( &flash11 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, " ----------------------------\r\n" );
Delay_ms( 100 );
}

Application Task

This example demonstrates the use of the Flash 11 Click boardâ„¢. The demo application 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_1 );
{
log_printf( &logger, " Erase memory block (4KB)\r\n" );
}
memcpy( data_buf, DEMO_TEXT_MESSAGE_1, strlen( DEMO_TEXT_MESSAGE_1 ) );
if ( FLASH11_OK == flash11_memory_write( &flash11, STARTING_ADDRESS_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 ) );
if ( FLASH11_OK == flash11_memory_read( &flash11, STARTING_ADDRESS_1, data_buf, sizeof( data_buf ) ) )
{
log_printf( &logger, " Read data: %s\r\n", data_buf );
Delay_ms( 3000 );
}
log_printf( &logger, " ----------------------------\r\n" );
log_printf( &logger, " Memory address: 0x%.6LX\r\n", ( uint32_t ) STARTING_ADDRESS_2 );
{
log_printf( &logger, " Erase memory block (4KB)\r\n" );
}
memcpy( data_buf, DEMO_TEXT_MESSAGE_2, strlen( DEMO_TEXT_MESSAGE_2 ) );
if ( FLASH11_OK == flash11_memory_write( &flash11, STARTING_ADDRESS_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 ) );
if ( FLASH11_OK == flash11_memory_read( &flash11, STARTING_ADDRESS_2, data_buf, sizeof( data_buf ) ) )
{
log_printf( &logger, " Read data: %s\r\n", data_buf );
Delay_ms( 3000 );
}
log_printf ( &logger, " ----------------------------\r\n" );
}

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.Flash11

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.
