I just updated EMC2 on the Sherline CNC mill from 2.4.6 to 2.4.7 (which mis-identifies itself as 2.4.6 on the splash screen) and the Axis UI failed to start. A bit of digging shows that the name of Button 1 (the left button in the right-hand quad, clearly labeled 1) has inexplicably changed from btn-trigger to btn-joystick.
Most likely the change has nothing to do with EMC2, because (I think) those names bubble up from the HID driver that actually talks to the hardware and that stuff has also been updated; this is all on Ubuntu 10.04 LTS. But in any event, the name is now different.
That requires a tweak to the Eagle schematics, which will regenerate Logitech_Gamepad.hal, but you can just edit the latter file and change btn-trigger to btn-joystick.
As nearly as I can tell, changing the pin name in the Logitech library component, saving the library, then updating the library in the schematic doesn’t do squat. Evidently, Eagle keeps track of which components you’ve used and won’t update them unless you do some manual gymnatistics, which makes a certain amount of sense.
That means one must:
- Delete both “gates” of the old component (INPUT.0.BUTTONS first, then INPUT.0)
- Make sure you’re on Page 2 where the basic gate will go
- Add the revised LOGITECH_DUAL_ACTION_GAMEPAD to get the INPUT.1 “gate”
- Rename it to INPUT.0
- Use Move to jiggle it around a bit to ensure its pins get hitched up to the existing nets
- Switch to Page 1 where the button nets lie in wait
- Type invoke input.0 into the Eagle command line
- Pick -BUTTONS from the list to select that “gate”
- Position that gate appropriately
- Use Move to jiggle the gate
- Save everything
- Run the Eagle2Hal ULP to get a new HAL output file
- Put that file where it’ll do the most good
There, now, wasn’t that obvious?
