IrDA Additional Board
The IrDA additional board is used for wireless communication carried out via infrared waves. This board includes an infrared transceiver
modul TFDU4101 used for serial communication with devices transferring data via infrared waves such as printers, fax machines,
notebooks, industrial devices, etc. The MCP2155 circuit provided on the board is used to convert data received from the transceiver
module and send it to the microcontroller for further processing. The IrDA board communicates with a microcontroller via serial
communication UART.
The TFDU4101 infrared transceiver module can send and receive data in the scope of over
1m at a rate of up to 115.2kbit/s. The data rate depends on the MCP2155 circuit and position
of jumpers B1 and B0. Refer to the table on the right. DIP switch SW1 is used to select a
development system to be connected to the additional board, Figure 2.
Labels used in the table have the following meaning:
E - Jumper is placed (Enable)
D - Jumper is removed (Disable)
