8031 / 8051 is a versatile micro-controller. This controller
finds extensive applications in automation. This is
because of its architecture and built-in I/O capabilities.
The use of this controller considerably reduces the
chip count in the final product design. Hence this finds
extensive applications in automatic vending machines,
weighing machines, welding machines, microwave ovens,
Coin box telephone instruments, EPABX system etc. Therefore
it becomes necessary to study the function and its capabilities,
by experimentation.
The Micro-controller trainer is a PC compatible instrument.
This has 8KB RAM (Optional 32K), 8KB EPROM. The instrument
is connected to serial port of computer at RS232C port.
A 50 pin FRC connector provides un-buffered Address,
Data, and control lines. This may be used for system
expansion at a later date. An additional power supply
of +5V DC @ 500mA and ±12V DC @ 500mA is required
to energize this.
FEATURES
It has features to modify and display internal as well
as external memory locations.
Move a block of memory from a source address to destination
address.
Execute from a specified memory location.
Display contents of all register and alter a few or
all registers.
