Click library

Software Support

We provide a library for the Sram 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 Sram Click driver.

Standard key functions :

Example key functions :

Examples Description

SRAM Click write and read data from 23LC1024 Serial RAM device.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.

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_printf( &logger, "--------------------------\r\n" );
log_printf( &logger, " Application Init\r\n" );
Delay_ms ( 100 );
// Click initialization.
sram_cfg_setup( &cfg );
SRAM_MAP_MIKROBUS( cfg, MIKROBUS_1 );
sram_init( &sram, &cfg );
log_printf( &logger, "--------------------------\r\n" );
log_printf( &logger, " ------ SRAM Click ----- \r\n" );
log_printf( &logger, "--------------------------\r\n" );
Delay_ms ( 1000 );
log_printf( &logger, " -- Initialization done --\r\n" );
log_printf( &logger, "--------------------------\r\n" );
Delay_ms ( 1000 );
}

Application Task

SRAM Click communicates with register via SPI protocol by write data to and read data from 23LC1024 Serial RAM device. Results are being sent to the UART where you can track their changes. All data logs on USB UART for aproximetly every 5 sec.

void application_task ( void )
{
log_printf( &logger, " Writing text :\r\n" );
for ( n_cnt = 0; n_cnt < 16; n_cnt++ )
{
Delay_ms ( 100 );
log_printf( &logger, "%c", send_buffer[ n_cnt ] );
}
log_printf( &logger, "\r\n" );
log_printf( &logger, " Read text :\r\n" );
log_printf( &logger, "%s", &mem_data[ 0 ] );
log_printf( &logger, "\r\n" );
log_printf( &logger, "--------------------------\r\n" );
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.
