Sin/Cos encoder with Teensy 4.0 hardware quadrature decoders

Discussion first, movement commences at 1:20

This is a demonstration of how to feed the hardware quadrature decoders on the Teensy 4.0 with a Sin/Cos analog differential encoder signal.

I am using a Renishaw RGH24B Sin/Cos encoder embedded in a Parker MX80L linear motor stage to test.

There are two projects I am planning to use this for.
- First, an update to my Sin/Cos and Incremental Quadrature Encoder Tester
- Second, a more generic version of the "HP5508A interferometer display" replacement that can also accept homodyne interferometer inputs.

Nice, I picked up a Renishaw ML10X and got it running. It has different quad output on the connector inside the box. Think I till try this with the teensy 4.0 and the uMD software you have on your page. Just waiting for some line receivers to show up.
