dogtopus / softpotmagic Goto Github PK

hello,

first, thanks for that library that helped me a lot in my project,
but i still have a problem, i use 3 softpot on my arduino and i want to know how i can apply the fonctions of your library on the 3 of them.
(excuse me if my english isn't that good, i'm french)

Mattéo.

Sometimes tapping and releasing the SoftPot will give weird readings (suddenly jumps to arbitrary numbers, etc.) probably due to lack of debouncing routine (and no ResponsiveAnalogRead does not help in this case because it is too responsive)

Floating-point arithmetic is not only slow, but also consumes a lot of program spaces on some hardware. Besides that, the code does not use a lot of FP arithmetic at all, so it should be easy to remove the dependency on FP all together.

The current implementation of blobThreshold (aka minimum gap between 2 touch points) is somewhat confusing and conterintuitive and needs clarification.

Things to do:

• Change the name of {get,set}BlobThreshold to things like {get,set}MinimumGapRatio and use a float between 0 to 1 as a way to represent the gap size instead of using the internal relative resistance representation.
  • The code also needs to be refactored so that it calculates the relative resistance from the ratio the user supplies.
• Add brief explaination in example code and README about what it does and how will it affect the result of sensing.
