Excelon LP Click carries a ferroelectric RAM module. Ferroelectric RAM, also known as FRAM, is a non-volatile memory type, with characteristics comparable to much faster DRAM memory modules.
We provide a library for the ExcelonLP 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.
This library contains API for ExcelonLP Click driver.
Config Object Initialization function.
void excelonlp_cfg_setup ( excelonlp_cfg_t *cfg );
Initialization function.
EXCELONLP_RETVAL excelonlp_init ( excelonlp_t ctx, excelonlp_cfg_t cfg );
Functions for send opcode command
void excelonlp_send_command ( excelonlp_t *ctx, uint8_t opcode );
Functions for read data
void excelonlp_read_data ( excelonlp_t ctx, uint8_t opcode, uint8_t out_buf, uint8_t n_data);
Functions for write data to memory
void excelonlp_write_memory_data ( excelonlp_t *ctx, uint8_t opcode, uint32_t addr, uint8_t c_data);
This application writes in RAM memory and read from RAM memory.
The demo application is composed of two sections :
Initializes Device init
void application_init ( void )
{
log_cfg_t log_cfg;
excelonlp_cfg_t cfg;
/**
* 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.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
excelonlp_cfg_setup( &cfg );
EXCELONLP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
excelonlp_init( &excelonlp, &cfg );
}
Reads device ID, writes 6-bytes (MikroE) to memory and reads 6-bytes from memory

for( cnt = 0; cnt < 9; cnt++ )
{
log_printf( &logger, " 0x", out_buf );
Delay_100ms();
}
log_printf( &logger, "\r\n" );
log_printf( &logger, "Write MikroE data." );
excelonlp_send_command( &excelonlp, EXCELONLP_OPCODE_SET_WRITE_ENABLE_LATCH );
for ( cnt = 0; cnt < 6; cnt++ )
{
excelonlp_send_command( &excelonlp, EXCELONLP_OPCODE_SET_WRITE_ENABLE_LATCH );
excelonlp_write_memory_data( &excelonlp, EXCELONLP_OPCODE_WRITE_MEMORY_DATA, memory_address++, send_buffer[ cnt ] );
Delay_100ms();
}
memory_address = 0x00000055;
log_printf( &logger, "Read memory data: " );
for ( cnt = 0; cnt < 6; cnt++ )
{
memory_data[ 0 ] = excelonlp_read_memory_data( &excelonlp, EXCELONLP_OPCODE_READ_MEMORY_DATA, memory_address++ );
log_printf( &logger, " %d", memory_address );
Delay_100ms();
}
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
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.
