| Summary: | The objective of the project is to develop the hardware and software for communication between two microprocessors. There are two ways of communication; serial and parallel transfer of data. By using an ACIA Chip, the serial transfer of data can be attained. For long distance communication it is more economical to use existing communication facilities. Telephone lines can be used but it is mainly designed for voice communication. The bandwidth requirement for digital communication is much higher than for voice communication. Hence for communication between microprocessors using telephone lines, the digital signals have to be suitably converted to analog signals which meets the bandwith constraints of the lines. The system proposed here uses frequency shift keying (FSK), and it is realized by using a MODEM chip. |
