Microcontroller applications with the Basic
Stamp, PIC, 8051 and various others can often be enhanced with the use of
the PC serial port, and a software interface. Designing your own custom
interface software for your next microcontroller application isn't as hard as
you may think.
Using the PC serial port to
interface to the outside world, and your next microcontroller application, can
provide you with some extremely powerful software/hardware solutions.
This series of articles by Jared
Hoylman will walk you through a few of the basic concepts, and then move on to
the more advanced areas of communicating with your hardware, and having your
hardware communicate back to the PC.
