TEXT on parallel port
hi
READING data from parallel port can be done in many ways, u can use C/C++, VB and many other languages, the easiest way (which i think is) use LABVIEW, there is a built-in VI in labview for this purpose.
If you want to send some data to FPGA via parallel port than you can use fpga pins (I/0) pins. Connect the wires from the pc parallel port to fpga pins. The parallel port is TTL (0 - 5v) so i think you dont have to attach any circuitry but using a buffer (like 74HC245) would be better. There is a special format of data entering/leaving from parallel port, the data is either sent in the form of a BYTE or a WORD. There is no such thing as buad rate in parallel comm, the speed of the data deprnds on the processor (speed) you are using.
