The 2051 is driving the 8255 board via a printer port cable. The 8255 is then connected to a Dontronics DT203 switch led board via a prototype board...

  درايور نويسنده پيام با ۸۹C2051  By using a Dontronics DT004 Simmbus mother board it is possible to use the micro-controller of your choice to drive equipment that is designed to be controlled by a PC via it's parallel port. In this example the device to be controlled is a walking message display. In Silicon Chip magazine February 1997 edition there was an article...

IBM Parallel Printer Portبقیه در ادامه مطلبIBM Parallel Printer Port The IBM parallel printer port is a gold mine of interface bits, both input and output. Most IBM compatible parallel printer cards can be set to respond as either LPT1: or LPT2:. These devices appear within the microprocessor's I/O address space as three separate eight bit ports, which will subsequently be referred to as...
