just curious writing some code here how do people handle scaling an encoders value when its attached to a shaft that has 360 degrees of rotation. i have always seen it done SCP Scaled Min 0 Scaled Max 360, but that doesnt make sense to me because thats technically 361 numbers no? since the 0 is counted? or am i missing something.
SCP for full circle rotation, 359 or 360 degrees?

It may be 361 numbers, but it is 360 intervals.
Just as a full-scale reading may go from 0 to 100 percent, a circle goes from 0 to 360 degrees, where just before 360=0, is 359.9999...

is this an incremental or absolute encoder?
is this a quadrature encoder?
does the process backup any?

its an absolute encoder. push-pull output, binary. during the process the encoder would only go in one direction, but there is the possibility of it going either way.
integers only i would like it should be 0-359, if i have an encoder with the resolution that i could get down to tenths of a degree, 359.9, then i would assume the scaling should be 0-359.9, not 0-360.0

0 to 359, or 1 to 360.
Depends upon whether you prefer to call the zero point "0" or "360".

id prefer to call the ZERO point 0.
whats interesting is im looking through code written by other programmers previously within my company and im seeing 0-360 on these SCP's and its just not making sense to me how that was deemed correct

for a 1024 PPR encoder, your scaling should be
0 = 0, 1023 = 359.6484375, 1024 = 360
Note that although you will never normally see 1024, you can use it for your scaling factor.
