        The cause of the slope might not be a "problem". I have found that some
servos will not be at minimum at 1ms, have you tried a shorter signal, say
0.9ms?

        Now the fact that it is sloping is kind of strange, the PIC can drive quite
a bit, what time scale are you looking at the falling edge? Perhaps your
time scale is really small? TTYL
