Click library
- Author : MikroE Team
- Date : May 2020.
- Type : SPI type
Software Support
We provide a library for the Bee 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 Bee Click driver.
Standard key functions :
bee_cfg_setup
Config Object Initialization function.
bee_cfg_setup
Config Object Initialization function.
Example key functions :
bee_read_rx_fifo
Read RX FIFO function
bee_write_tx_normal_fifo
Write TX normal FIFO function
Examples Description
This example demonstrates the use of an BEE click board by showing the communication between the two click boards.
The demo application is composed of two sections :
Application Init
Initializes the driver and configures the click board.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
for ( uint8_t cnt = 0; cnt < 2; cnt++ )
{
short_address1[ cnt ] = 1;
short_address2[ cnt ] = 2;

}
for ( uint8_t cnt = 0; cnt < 8; cnt++ )
{

long_address2[ cnt ] = 2;
}

log_printf( &logger, " - Set normal mode\r\n" );
log_printf( &logger, " - Device Wake Up\r\n" );
Delay_1sec( );
}
Application Task
Depending on the selected application mode, it reads all the received data or sends the desired message every 3 seconds.
{
#ifdef DEMO_APP_TRANSMITTER
log_printf( &logger, " - Sent data : " );
log_printf( &logger, "%.6s \r\n", data_tx1 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, " - Sent data : " );
log_printf( &logger, "%.6s \r\n", data_tx2 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
#else
if ( memcmp( &rx_data_fifo_old[ 0 ], &rx_data_fifo[ 0 ],
BEE_DATA_LENGHT ) )
{
log_printf( &logger, " - Received data : " );
log_printf( &logger, "%.6s \r\n", rx_data_fifo );
Delay_ms ( 1000 );
Delay_ms ( 500 );
}
Delay_ms ( 500 );
#endif
}
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.
Other mikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.Bee
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.
