5.15 Using IrDA

The DE2-70 board provides a simple wireless communication media using the Agilent HSDL-3201 low power infrared transceiver. The datasheet for this device is provided in the Datasheet\IrDA folder on the DE2-70 System CD-ROM. Note that the highest transmission rate supported is 115.2 Kbit/s and both the TX and RX sides have to use the same transmission rate. Figure 5.21 shows the schematic of the IrDA communication link. Please refer to the following website for detailed information on how to send and receive data using the IrDA link:
