Greetings Ladies n Gentlemen. ;-) I offer topics to discuss. 1. Some time ago there was an idea to talk about state machines and its implementation. Someone (I believe it was Mark Willis ;-) was offered a little lecture about state machines and its possible implementations for microcontrollers. So Mark, if you have a time right now or later I guess it will be very interesting topic. 2. In 50th the CORDIC algorithm was introduced (coordinate rotation) to simplify coordinate calculations in aviation. Since 50th alot of handheld calculators use this algorithm to compute various trig and other functions. So I guess it will be interesting for us to discuss usage of CORDIC in words of PIC world ;-) WBR Dmitry.
