BEE Click features MRF24J40MA 2.4 GHz IEEE 802.15.4 radio transceiver module from Microchip.
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.
This library contains API for Bee Click driver.
bee_cfg_setup
Config Object Initialization function.
void bee_cfg_setup ( bee_cfg_t *cfg );
bee_cfg_setup
Config Object Initialization function.
err_t bee_init ( bee_t *ctx, bee_cfg_t *cfg );
bee_read_rx_fifo
Read RX FIFO function
void bee_read_rx_fifo ( bee_t *ctx, uint8_t *rx_data );
bee_write_tx_normal_fifo
Write TX normal FIFO function
void bee_write_tx_normal_fifo ( bee_t *ctx, uint16_t address_tx_normal_fifo, uint8_t *tx_data );
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 :
Initializes the driver and configures the Click board.
void application_init ( void )
{
log_cfg_t log_cfg;
bee_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.

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.
