Here is a program part which i use for reduce 4 servo's speed :
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
-- basic position all servo's
servo_move(124,1)
servo_move(124,2)
servo_move(129,3)
servo_move(121,4)
---------------------------------------------------
var byte old_pos[4] = {124,124,129,121} -- start up beiden in centrum
var byte new_pos[4]
var byte tell =0
-----------------------------------------------------
---------------------------------------------------
procedure set_servo_pack (byte in x) is
var byte flag = 0
var byte tell = 0
while flag < 4 loop
flag = 0
tell = 0
for 4 loop
if old_pos[tell] < new_pos[tell] then
servo_move((old_pos[tell] + 1),tell+1)
old_pos[tell] = old_pos[tell] + 1
delay_1mS(x)
end if
if old_pos[tell] > new_pos[tell] then
servo_move((old_pos[tell] - 1),tell+1)
old_pos[tell] = old_pos[tell] - 1
delay_1mS(x)
end if
if old_pos[tell] == new_pos[tell] then
flag = flag + 1
end if
tell = tell +1
end loop
end loop
end procedure
