Using IrDA
The DE2 Board also provides a simple wireless communication media using a
115.2Kb/s Low Power Infrared Transceiver. Please refer to the specification in
C:\DE2\DataSheet\IrDA for detail information. Note that the highest
transmission rate is 115.2kbit/s and both TX and RX sides have to use the same
transmission rate agreed. Figure 3.16 shows the schematic of IrDA
communication link. Please refer to the following website for detailed information
on how to send and receive data using the IrDA link:
http://techtrain.microchip.com/webseminars/documents/IrDA_BW.pdf
The pin assignment of the associated interface is shown in Table 3.14.
