servo motor resets 16f877a

If you have an oscilloscope look at your control pulses from the PIC to the servo as it moves. If you see that the wave form (1~2ms pulse) is wiggling around or changing amplitude then you have a power supply issue. Do as I suggested above, get a 9v power supply (AC/DC) and use TWO 7805 regulators in parallel for the servo ONLY. At the servo use 470uF across power and ground. Look at the scope again and make sure you see a "cleaned" up signal while servo is in motion.

I tried everything which is suggested.I changed code and put PAUSEUS before pulsout.Something wrong ,I got same error I decided to change power supply.That can cause this problem.

I hope it will solve my problem...

I will use two servos...(one for left-right one for up-down).I wrote the code just for left-right.I will make servos TWO if I am successful left-right position...

Why did you say two parallel 7805? One for pic and one for servo?

How many 7805 regulators should I use?
