I've added the TI Hercules LaunchPad and Xilinx FPGA tests.

I still have to upload the FPGA video. That's something for tonight.

thank you very much, works perfectly :-)

I've added a blog on that implementation on a Cypress PSoC: Rotary Encoders - Part 2: Capturing Input on a Cypress PSoC4

Here's a link to an article I wrote awhile ago about a simple software decoding method which copes well with edge uncertainty which can be an issue with low cost optics.

Apologies for the rather old style C !

Really great analysis! I should use this starting point in the future. Not yet applied rotary encoders in projects as I have always found a workaround but this is a clear approach.

When part 2 ? [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-6c2c91c9-7142-4e5d-a488-e25884e3223e/contentimage_5F00_2516.png:16:16]

I enjoyed your analysis so far and will look forward to any additional posts about the quadrature encoder. I took some optical encoders out of a printer a couple months ago and had some fun figuring them out. Thanks for sharing.

I think you are dealing with a standard Quadrature encoding.

You can decode it with a component in your Cypress PSOC.
