: : HELLO COULD YOU PLEASE HELP ME OUT. MY PROBLEM IS THAT I AM BUILDING A PROJECT THAT REQUIRES ME TO INTERFACE ABOUT 3 OR 4 CIRUITS TOGETHER. CAN I USE A MICROCONTROLLER TO CONTROL THE OPERATION OF THESE CIRCUITS. THE OPERATION OF THE CIRCUITS HAVE TO FOLLOW A CERTAIN ORDER FOR EG A TELEPHONE RING MUST FIRST BE DETECTED THEN THE TELEPHONE LINE MUST BE SEIZED THEREAFTER A DELAY MUST BE CREATED AND FINALLY ANOTHER CIRCUIT MUST BE ABLE TO DETECT A FAX TONE AND THEN SWITCH TO THE FAX OR TELEPHONE (TELEPHONE FAX LINE DETECTOR). WHAT IS THE PROCEDURE INVOLVED IN ORDER FOR ME TO START IMPLEMENTING THIS ON THE MICRCONTROLLER . WHAT PROGRAMMAING LANGUAGES DO I HAVE TO KNOW
:
: It might be worth to look at the following project page:
: EE476 Final Project
: AT90LS8515 PBX (Private Branch Exchange
: http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2001/pr57/REPORT.htm
: I think reading this document through will give you useful information for making your own project.
