Yes, and it works, and we have a dedicated driver for it in our drivers library that you can use!
It uses the SSI interface. I2C isn’t implemented yet.
Because of the SSI protocol, which is implemented using the SPI peripheral of the MCUs but isn’t exactly the same as real SPI, some MCUs only see 13bits instead of 14. Let us know if you have a problem like that.
To use it in ABZ mode you can just use our normal Encoder class.
