Hi there,

Most probably a old issue on the list. But what is the difference =
between the internal and external reference? When will you be using the =
internal reference and when the other?=20

I have written a algorith on the pic to mathematically convert the =
10-bit number to a number between Ymin and Ymax but the algorithm takes =
far too long. Is there a way (hopefully easy) that you more or less can =
convert the 10-bit number to say between 100 and 200 almost directly =
(bit manipulation) without long and cumbersome arithmetic.

Thirdly, in the datasheet it is mentioned that it is best to use around =
10K pots for best results. Is this now to get the fastest charging of =
the capacitor and therefore the highest speed in the conversion or is =
there another reason, because I have a joystick that only uses  50K =
pots. What can I do to remedy this? Maybe put some resistor in parallel =
with this?

Regards

Nic Scheepers
