Okay dann hier alles, was es dazu braucht. Da ich vorher alles sorgfältig gelesen habe, kann ich keinen Fehler an einem falschen Buchstaben feststellen. Aber ich hab ja auch nur 2 Augen. =)

// Servo constants:
#define SERVO1 0b00000001
#define SERVO2 0b00000010
#define SERVO3 0b00000100
#define SERVO4 0b00001000

#define SERVO7 0b01000000
#define SERVO8 0b10000000
// Servo movement limits (depending on servo type):
// Standard Servos need an impulse every 20ms (50Hz). This impulse must have
// a length of 1ms (0.7 .. 1ms) to move the servo lever to the left touch
// and a length of 2ms (2 .. 2.3ms) for moving it to the right touch. In the
// middle position the servo needs an impulse length of 1.5ms (1.3 .. 1.6ms).
// If you want to modify the following constants for a certain servo type,
// you must adapt the LEFT_TOUCH constant first (values ~70 .. 100 = ~0.7 ..
// 1ms at 100kHz) by using a servo position value (servoX_position) of zero.
// After that you have two "screws" to adjust the servo movement limits:
// First you may change the RIGHT_TOUCH constant. If you choose a higher
// value than 255, you will use 16-bit values. Higher values mean a longer
// impulse length, but longer impulses than 2.3ms do not make sense.
// Second you may alter the Timer 1 frequency constant (F_TIMER1).
// A higher frequency leads to smaller steps of the servo movement. This of
// course reduces the impulse length and may be compensated again by a higher
// RIGHT_TOUCH constant. As a possible range of Timer 1 frequency values you
// may use 50kHz (20us) .. 105.263kHz (9.5us).
// HINT: If you alter F_TIMER1, you'll have to adapt LEFT_TOUCH and
// RIGHT_TOUCH again as you can see in the following table!
// Steps -> 9.5 10 12.5 15 17.5 20 [us]

[EDIT]
Ist es möglich, dass der Port D mehr belastet werden kann als Port C ?? Wenn ich den Servo als Servo 8 am IO_PD6 anschliesse, stürtzt nichts mehr ab. [/EDIT]
