Data communication rates up to 86.4 kbaud Includes UART-to-IrDA standard bit encoder/decoder functionality Provides interface to IrDA-compliant transceivers with 1.63Ás Transmit/Receive format Integrated IrDA stack Configurable IDC10 interface Works on both 3.3V or 5V systems
The IrDA2 Board features the MCP2120 infrared encoder/decoder placed between the UART side and the IR transceiver side. It performs modulation/demodulation in accordance with the IrDA standard. The board also has a TFDU4101 infrared transceiver module compliant with the latest IrDA physical layer standard for fast infrared data communication.
The DIP switches on the board allow you to configure which pins on the IDC10 interface are used for RX/TX, and to set the MODE pin of the MCP2120. The user manual and silkscreen specify settings which are compatible with 2x5 port headers on PIC, dsPIC, AVR and 8051 development systems by mikroElektronika, so you can plug this board directly into one of those systems without needing to solder anything.
Use in your own design While this board was created originally for mikroElektronika's development systems, it's certainly possible to use in your own project. To do so, you may want to pick up IDC10 box headers that you can solder onto your PCB, or an EasyTEST board to wire it up easily.
Three jumpers on the board allow you to select between five bit rates. With this board's 11.0592 MHz crystal, they equate to 14400, 28800, 57600, 86400, and 172800 baud. Note that 172800 is beyond the specifications of the TFDU4101, which has a maximum supported baud rate of 115200.
