feature added with consumer key support.

compile:

$ make bin

compile & flash to pad:

• if on original firmware: depending on hardware you need to connect P3.6 to 5V (VCC) using a 1k resistor or P1.5 to GND, while connecting USB
• if on this firmware: press key1 while connecting USB
• $ make flash

configure keys:

1. $ isp55e0 --data-dump flashdata.bin
2. edit bytes from start to 3 * 6 bytes of this binary (3 keys, plus 3 for the knob, 3 bytes each - modifier, key type, key code), and write it back:
3. $ isp55e0 --data-flash flashdata.bin
