- i have made this code for the LMD18245 motor controller, 
-  i have merged the pid code of  Josh Kopel 
-    whith the code of makerbot servo-controller board,
-  you can use this code on the some board changing some values.
-  Daniele Poddighe
-   external ardware require a quadrature encoder, timing slit strip and a dc motor,
-   all you can find inside an old printer, i have took it from canon and hp printers(psc1510)
-   
-   for motor controll you can choose different type of H-bridge, i have used LMD18245,
-   you can order 3 of it on ti.com sample request, the hardware needed is explained on the datasheet but i'm drowing
-   the schematic and PCB layout on eagle.
-   
-   
-   read a rotary encoder with interrupts
-   Encoder hooked up with common to GROUND,
-   encoder0PinA to pin 2, encoder0PinB to pin 4 (or pin 3 see below)
-   it doesn't matter which encoder pin you use for A or B 
-   
-   is possible to change PID costants by sending on serial interfaces the values separated by ',' in this order: KP,KD,KI
-   example: 5.2,3.1,0 so we have  KP=5.2 KD=3.1 KI=0 is only for testing purposes, but i will leave this function with eeprom storage
-   
-   This code use Port manipulation :
-   Port registers allow for lower-level and faster manipulation of the i/o pins of the microcontroller on an Arduino board. The chips used on the Arduino board
-   (the ATmega8 and ATmega168) have three ports: 
-    B (digital pin 8 to 13)
-    C (analog input pins)
-    D (digital pins 0 to 7)
