I was reading through the AXE031 documentation again and I found something that loooked interesting.
Now there are several sets of registers in the AXE031. A high precision one with the capability of setting the speed (16bit position and 8bit speed), and a low precision one (8bit position) but NO speed.
However I read that the AXE031 internally converts the low precision register to the 16 bit one - basically 6 high precision points for every 1 low precision points.
I send a quick question to a UK firm and they have confirmed this.
Setting the speed and then setting a low precision register will enable the speed function on an AXE031.
So if you want an slow movement on your servo and not waste a byte in storage you can do the above
Hope this helps.
