Circuits, Programs,
& Applications featuring the 8052 BASIC Microcontroller
(8052, member of Intel 8051 microcontroller family)
The Microcontroller Idea Book by Jan Axelson focusses
on the 8052 BASIC microcontroller. It takes the reader
who may essentially have no knowledge of programming through
BASIC while offering considerable insight into the design
of simple embedded systems.
It is a hands on guide to designing, building and testing
microcontroller based devices. The ideas and applications
presented here are not limited to the 8052-BASIC. If the
reader is used to working on a different chip, you can
adapt the circuits and programs can be adapted to it.
The schematics and programs listings in this book include
comments and explanations to help apply the ideas irrespective
of whether one is using the 8052 BASIC microcontroller.
It is not just a textbook that presents information, but
gives details of how to apply it. With the collection
of input / output circuits provided, it helps to connect
to the outside world and have it all work properly.
Both, the hardware and the software aspects have been
epitomized as microcontroller projects involving both
circuit design and programming.
Some of the features of the book are:
- Complete circuit schematics and parts list - so one can easily build the circuits
oneself.
- Design theory - for example, why use this particular component or modify the circuit shown.
- Example program listings - for easy testing and use of the circuits.
- Construction and debugging tips
- to help get the circuits up and running with no
problems.
- How to add sensors, relays, displays, clock/calenders,
keypads, wireless links and more.
