There is a slight CPU usage problem when using VoodooI2C, but I think it's mostly when you actually touch the trackpad. Remove the kext to verify, I guess...

See this error in the kernel log:

Implementing GPIO interrupts is much more efficient - will help with the CPU usage.
Polling is just a temporary solution, until you implement interrupts (Or for systems with buggy GPIO implementation - in that case they must use polling).

Some users report the cursor jump issue as well. Implement GPIO interrupts and see if the issue persists.
Is it OK , now ?

I'm on VoodooI2C + VoodooElan v2.1.4 - Asus Skylake - ELAN1000

in VoodooI2C 2.1.4, clicking the bottom right corner of the trackpad for right-click doesn't work anymore. The bottom right corner right-click still works fine on v2.0.3.

In 2.1.4, even if I set the bottom right corner for right-click in the trackpad settings, it still doesn't work.

v2.1+ is using the native multitouch engine of macOS by emulating a Magic Trackpad 2.
That's why right click stopped working.
As you've set it in sysPrefs and it still doesn't work, I can assume it's a scaling problem.
After searching it, the cause is confirmed:
https://github.com/alexandred/VoodooI2C/issues/108

See this commit for a fix:

You may try it and compile yourself. With or without changing the ID to 0x265 (try without first).

Hi all,

I would like to report an issue with ELAN1200 trackpad. I got it working perfectly with Sierra 10.12.6, but the trackpad doesn't work anymore after update to Mojave 10.14.2.

Actual result:
Trackpad cursor movement works only on the login screen. Cursor movement suddenly stops working after login to the desktop. Only trackpad buttons work without any issues.

Expected result:
Trackpad cursor movement works all the time.

Please find problem reporting files attached.

Could you please advise on how to fix this?

Thanks,
Petr

Can someone check if I installed I2c trackpad right?
Only problem I see is sometimes when cpu spikes cursor hags for a ms.
Thanks in advance.
