- Split the PWMs across two controllers to make it easier to match the PWM naming convention.
- Add cape GPIOs for P9 and upper P8 using cape pin naming convention Px_y.
- Adjust rotary encoder de-bouncing
- Rotaty encoder value are accessible from address 0x4130000 for the first encode and 0x41300010 for the second encoder.
