ArduPilot Mega: 1000-2000 usecond range for Servo

-

running 4 servos ardupilot mega board, using code below, little jitter...can any1 see if doing mistake?...
i running ardupilot mega (atmega1280) on 16mhz...


tccr1a =((1<<wgm11)|(1<<com1b1)|(1<<com1c1));
tccr1b = (1<<wgm13)|(1<<wgm12)|(1<<cs11);
ocr1b = 3000; //pb6, out2
ocr1c = 3000; //pb7 out3
icr1 = 40000; //50hz freq...

tccr5a =((1<<wgm51)|(1<<com5b1)|(1<<com5c1));
tccr5b = (1<<wgm53)|(1<<wgm52)|(1<<cs51);
ocr5b = 3000; //pl4, out0
ocr5c = 3000; //pl5, out1
icr5 = 40000; //50hz freq

how "a little"?  what rest of program doing?

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
