Abstract
A multiple programmable input/output port for digital data acquisition and control systems was designed and fabricated. the design consist of a decoding logic to address the proper address location and a programmable peripheral interface which manipulate the input/output operation as defined by the user. There were a total of three programmable ports which can be configured to 16 different combinations at mode zero operation. The ports were named port A, port B, port C, plus a control word input. The location of the following ports was 303H for the control word register, 300H for port A, 301H for port B, and 302H for port C. Each of the port can be defined as input or output. A program routine was written to illustrate how to access the different ports through a high or low level language. The language used in this program was Turbo Pascal V5.5. The hardware was tested using the said program routine by sending the output to light emitting diodes. Inputs were tested using toggle switches. The board proved to be working correctly as desired.
