1. EasyBee All Mikroelektronika s development systems feature a large number of peripheral modules expanding microcontroller s range of application and making the process of program testing easier In addition to these modules it is also possible to use numerous additional modules linked to the development system through the I O port connectors Some of these additional modules can operate as Stand alone devices without being connected to the microcontroller EJMikroElektronika SOFTWARE AND HARDWARE SOLUTIONS FOR EMBEDDED WORLD waking ib simple EasyBee Additional Board The EasyBee additional board is used for wireless communication between a development system and a device Wireless communication is enabled due to a ZigBee module operating at 2 4GHz and in compliance with the IEEE 802 15 4 standard Key features ZigBee transceiver operates in compliance with the IEEE 802 15 4 standard 2 4GHz operating frequency 5V or 3 3V power supply voltage and capable of connecting with various development systems How to connect the board Connection between the additional board and a microcontroller is established via a 2x5 connector supplied on the additional board and a 2x5 connector on the development system Figure 2 Communication between them is performed via a serial UART connection There are also six pads provided on the additional board which enable direct access to the UART pins RX TX RTS and CTS Th2. s compilers contain program description with necessary settings that should be performed for the development system in use Figure 4 The back of the additional board Development system Easy dsPIC UART Easy PIC BIG PIC LV 18FJ LV 24 33 dsPIC PRO Easy AVR BIG AVR Easy 8051 Easy ARM Table 1 Position of switches on the DIP switch SW1 In addition to the program examples you can download from Mikroelektronika s website you can also write and load your own program The EasyBee additional board may be configured to operate as a router connected to several devices supplied with the ZigBee module As such it is very useful in home automation systems with wireless communication ETI RES RBS IS mi DN OD e Q Py uee L GND SBBEBE R we FENN LG PORTC 3465 7 RCO IRCZ RC4 RC6 IRC MEDU 20 COG2x16 5 CONTRAST r Fi TER kej k el M ZL Z Z 2 2 SEL GI B Sech ES EE ETA TAT ze VER Up Figure 5 Additional board and development system connection schematic O m MikroElektronika VCC BRD CN2 GIG VCC REG OVCC BRD SCH I SC Me OVCC REG 10uF JI VCC BRD VCC 3 3 O Q VCC BRD O R9 m SP _CLK IRQ_6 m 1K VCC 3 3 CK ANIUSO IRQ 7 o Ni SPI MOSI GPIO8 m E GPIO0 USARTO_EXTCLK E E GPI01 USARTO_TXD E E GPI02 USARTO RXD m E OSC32K UART_DTRE E RESET GPIO_1WR m AGND E AVREFE BATT E M 2C_DATA ADC1 m UART TXD ADC2 m RX 3 UART RXD ADC3 m RTS 3 3 m
