I need some advise on building a digital angle display. It's for a faceting head, cutting and polishing gemstones, and I'm having a tough time with what path would be the best for me.
Basics that are needed are relatively simple:
- need to have 0.01° resolution, only need 0-90° range.
- compatible with arduino
Figuring out which sensors will have the desired resolution, and still work with Arduino, is my major hurdle. So far I haven't found any single sensor option that can fit. Unless someone can suggest another alternative, the two categories I've been considering are magnetic encoders or precision pots.
The as5048 from ams has code and boards for arduino available, but it's only good for 0.05° res, which is not quite accurate enough for me.
Then there is the aeat-6600-t16, from Avago, while is has the 16-bit res there isn't any pre written code(that I could find).
In searching the web I came across this sensor from SOC robotics, that uses a 3382 position sensor from bourns. They claim that it's a 16-bit sensor, but the 3382 has +-2% linearity which is way less than 16bit so idk about that one.
RP12 datasheet
Anybody done something like this and can help?
