FRAM 3 click

The FRAM 3 Click is a Click boardâ„¢ that carries a ferroelectric RAM module. Ferroelectric RAM, also known as FRAM, is a non-volatile memory type, with characteristics that are comparable to much faster DRAM memory modules.

Click library

Software Support

We provide a library for the FRAM3 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 FRAM3 Click driver.

Standard key functions :

Example key functions :

Examples Description

This application writes data in memmory and reads data from memmory.

The demo application is composed of two sections :

Application Init

Initializes device init

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
fram3_cfg_setup( &cfg );
FRAM3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
fram3_init( &fram3, &cfg );
}

Application Task

Writes and then reads data from memory

{
static char write_data[ 7 ] = { 'M', 'i', 'k', 'r', 'o', 'E', 0 };
static char read_data[ 7 ];
static uint8_t cnt;
static uint8_t status_check;
log_printf( &logger, " - Writing... \r\n" );
Delay_ms( 500 );
status_check = fram3_write_free_access_memory( &fram3, 0x00, &write_data[ 0 ], 7 );
if ( status_check == FRAM3_ERROR )
{
log_printf( &logger, " - ERROR WRITING!!! \r\n" );
for ( ; ; );
}
log_printf( &logger, " - Reading... \r\n" );
Delay_ms( 500 );
status_check = fram3_read_free_access_memory( &fram3, 0x00, &read_data[ 0 ], 7 );
if ( status_check == FRAM3_ERROR )
{
log_printf( &logger, " - ERROR READING!!! \r\n" );
for ( ; ; );
}
for ( cnt = 0; cnt < 7; cnt++ )
{
log_printf( &logger, " %c ", read_data[ cnt ] );
Delay_ms( 100 );
}
log_printf( &logger, " \r\n " );
Delay_ms( 1000 );
log_printf( &logger, "__________________________\r\n " );
Delay_ms( 500 );
}

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.

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.
