Flash 12 Click

Flash 12 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.


Click Library

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

Software Support

Example Description

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

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Flash12

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 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 ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
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 ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
