Knowing this the verilog code simply samples the Key presses and decodes the bit 13 bit value, the bits are sampled at the positive and negative edge of the **Blue** trace.
To control for debounce keys presses are sampled at 8 Hz and this is very close to the normal operation of the Brightness control in a non modified macbook.
To control for debounce keys presses are sampled as 5 at a time and the brightness level changes are clocked at 8 Hz, this is very close to the normal operation of the Brightness control in a non modified macbook.
As of yet there is no way of syncing the on-screen pop up brightness level indicator so this is not accurate and should be disregarded. But more modifications may enable this functionality later.
