Design, development and implementation of a PC-Based programmable peripheral I/O devices trainer

The miracle chip microprocessor represents a quantum leap in the technology of mankind, a development that over the past decade has acquired the significance in industrial automation and has led PCs to become workhorses in the everyday industrial environment. The communication of Microprocessor to the outside world depends upon the I/O devices and Interfacing Techniques. This work deals with the technique of interfacing Intel, Motorola, and Zilog processors, with their respective I/O devices (PPI, PIA, and PIO) for parallel data transfer. The PC based trainer is specifically designed to demonstrate how a particular microprocessor selects and initializes an I/O device, what hardware chips are necessary, what software instructions are used, and how various data transfers take place. Many practical exercises can be developed in software to expose students to more complex applications using PC-based Programmable Peripheral I/O Devices Trainer. (author)
