"Fuzzy" Project
I am fascinated by the concept of "Fuzzy Logic" for real time control of
processes. This application is a simple introduction to it (as well as the PIC18CXX2) and
will give you an idea of how Fuzzy Logic applications are developed. While you require
"fuzzyTECH" to run this application completely, it can be used as a basis for understanding
how PIC18CXX2 microcontroller applications are created.
Click Here to look at the PICmicro MCU
source code.
The circuits used for this application are:
