| dc.description.abstract | An inexpensive, portable, versatile, microprocessor based data acquisition
system is presented. The design and development of the system
hardware and software is described. The system is software intensive
consisting of 2 Kbytes of monitor program and 1 Kbyte of application
programs. It is configured to operate on a Z-80 microprocessor running
at 2 MHz. It is programmed using a microcomputer through a serial port
to meet specific requirements of data to be acquired which include
calibrating specific input devices. A maximum of 16 analog signals in
the range ojO-5 Volts can be simultaneously monitored by this system.
Data is logged in the system in two modes. In the normal mode it
acquires data at a maximum rate of 1 reading in 2 microseconds.
Whereas in the interrupt mode with the real.time dock it takes 1 reading
in 10 milliseconds. The main board storage capacity is 5 Kbytes but it
has an additional capacity of 40 Kbytes 8H the RAM expansion card. | en |
