[ 1 ] - An Intelligent Computer Interface Utilizing Parallel Picocontrollers (TECHNICAL NOTE)
The design of an interface unit is described, in which RS232 serial data is converted to latched parallel data on 22 independent lines. The data direction of each line is programmable through the serial port. Two picocontrollers are employed in a parallel processing mode to give the required number of I/O pins, and data on the shared serial line is coded to separate data streams to the individu...
[ 2 ] - The Opportunities Afforded by Embedded Computer Systems for Monitoring and Control of Industrial Processes in Less-Industrialised Countries (TECHNICAL NOTE)
The dramatic changes in integrated-circuit technology over the last two decades have been of great benefit to countries such as Zimbabwe. High volume production of VLSI chips has produced a supply of intelligent, versatile electronic processing devices at very low cost. In particular the facilities of the microcontroller have steadily developed to the accompaniment of a reduction in price. Sinc...
