I'm looking at an alternative to the Rotary Encoder and looking at this Blackberry Trackball breakout board as seen below.
I'm looking to get the the LEFT/RIGHT or DOWN/UP to replace the Rotary Encoder anti-clockwise/clockwise directions.
As a direct/drop-in replacement for the Rotary Encoder, I am finding that I can get the switch/button to work; but for file selection direction I can only get it to work in the 'clockwise' direction - the one that is connected to the CK pin (as per https://hxc2001.com/docs/gotek-floppy-e ... otary.html). If I connect the CK pin to any of UP, DOWN, LEFT and RIGHT (well actually not RIGHT, since I have a hall effect chip missing on my board, if you look carefully at the picture below), the I can get the file selection to move right/clockwise.
Would it be possible to get support for this trackball so that it works in both directions - i.e for the DIR pin to receive input like the CK pin?
Code: Select all

EDIT: More technical details about the trackball breakout board can be found below. It's not exactly the same board, but the it is good reference material:

Specifically, the schematics:

EDIT: For the LEDs, I can only turn it either on or off, since the LED pins are meant to connected to a VCC source. So I cannot get it to flash for disk activity, like I can for the RGB encoder.
