4 Sub-State (quarter step) encoder reading enhancement instead of the halfstep in original code #7

Closed ardlc-1212 closed 1 year ago

Hi, I made a "4 sub-state counting for each line on the encoder" update to the program using 2 state machines. Unfortunately I didnt had the hardware to test it so I am hoping someone with the right hardware can. Here is the code 😄 :

pi-pico-pio-quadrature-encoder-main.zip

I am happy to contribute to such a cool project I hope this becomes the new big feature <3.

Quick note: I don't have any idea about the licencing protocols so I just left them as is

Quick note 2: to read the value we have to read both of the sm and add them together.

Update: I used the y register to increment and kept the values consistent on each reading too.

With Love and Sleep Deprivation, Arda

Hello it's update time I just got my hands on an encoder and fixed a couple of bugs here and there this updated version seems to work flawlessly. I am excited to use these on my projects. (note that I didnt tried using it on pins other than 20 and 21 because my pcb layout wouldn't allow me to do so, but that shouldn't be a problem c-sdk should handle it easily)

@ardlc-1212 Is all the code you've modified/added your own work? and do you agree to license it under the same license as the repository (MIT)?

as a side-note, if you're interested, I'm happy to grant you commit permissions, as well.

It is my own work and I agree to license it under the same MIT licence

Also I would love to get commit permissions, always happy to be a part of the community :)

@jamon Can you set up the readme, license files etc to include me and publish it. I would love to do it but I am kinda busy right now with an approaching exam.

Here's my info if you can include that on the file too:

Thanks in advance, Arda

Yeah--It will take me a bit to get to it as well though, I need to get my test rig set back up :)
