MAC Address Click provides a unique node address for your application. It also has 1Kbit of writable EEPROM memory.
We provide a library for the MacAddress 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 MacAddress Click driver.
Config Object Initialization function.
void macaddress_cfg_setup ( macaddress_cfg_t *cfg );
Initialization function.
MACADDRESS_RETVAL macaddress_init ( macaddress_t ctx, macaddress_cfg_t cfg );
Generic read mac address function
void macaddress_get_mac ( macaddress_t ctx, uint8_t read_mac );
Generic read the byte of data function
uint8_t macaddress_read_byte ( macaddress_t *ctx, uint8_t reg_address );
This application provides a unique node address for your application.
The demo application is composed of two sections :
Initialization driver enables - I2C, also write log.
void application_init ( void )
{
log_cfg_t log_cfg;
macaddress_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.
macaddress_cfg_setup( &cfg );
MACADDRESS_MAP_MIKROBUS( cfg, MIKROBUS_1 );
macaddress_init( &macaddress, &cfg );
macaddress_get_mac( &macaddress, mac_addr );
log_printf( &logger, " > MAC Address: 0x" );
for ( uint8_t cnt = 0; cnt < 8; cnt++ )
{
log_printf( &logger, "%02X", (uint16_t)mac_addr[ cnt ] );
}
log_printf( &logger, "\r\n" );
Delay_ms ( 1000 );
log_info( &logger, "---- Application Task ----" );
data_cnt = 0;
}
This is an example which demonstrates the use of MAC Address Click board. MAC Address Click communicates with register via I2C protocol by the write to register and read from the register. This example shows write/read sequential write/read from EEPROM. Results are being sent to the Usart Terminal where you can track their changes.
void application_task ( void )
{
log_printf( &logger, " > Writing data to memory...\r\n" );
Delay_ms ( 100 );
macaddress_generic_write( &macaddress, address, write_data[ data_cnt ], data_len[ data_cnt ] );
log_printf( &logger, " > Writing done.\r\n" );
Delay_ms ( 1000 );
log_printf( &logger, " > Reading data from memory...\r\n" );
macaddress_generic_read( &macaddress, address, read_buff, data_len[ data_cnt ] );
Delay_ms ( 100 );
log_printf( &logger, " > Read data: " );
for( uint8_t cnt = 0; cnt < data_len[ data_cnt ]; cnt++ )
{
log_printf( &logger, "%c", read_buff[ cnt ] );
}
log_printf( &logger, "\r\n" );
Delay_ms ( 100 );
log_printf( &logger, " > Reading done.\r\n" );
log_printf( &logger, "---------------------------------\r\n" );
data_cnt++;
if ( data_cnt >= 3 )
data_cnt = 0;
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.
