Hi LawrencL
The Hservo is only available on the Atom Pro. I checked the programming manual and it’s not in there. There is a pretty good explanation of it here though… lynxmotion.com/images/html/build033.htm
and here… lynxmotion.com/images/html/build037.htm
I think; the Atom Pro 24 has 4 A to D’s on the first 4 I/O pins. The Atom Pro 28 has 4 more on the extra 4 I/O pins. The Atom 28 has 4 on the extra I/O pins labled AX0, AX1, AX2, AX3.
Hope this helps…
