Left split encoder zmk support?

There appears to be working code for left side split encoder support. On my build with the Xiao BLE board, I've wired the left half up to use the NFC pins (gpio mod) for EC11 signal lines, so the OLED can be on I2C and the left encoder can coexist. Obviously, the push switch wiring on the PCB is already there anyway...

Figured out after that hardware move that left split encoder software support isn't in the main branch of ZMK: https://github.com/zmkfirmware/zmk/pull/728

I don't know how difficult it will be to add this infused-kim branch to support left split encoders, but maybe you'll be able & willing to look at it? I'm really interested in getting it working, but kind of out of my depth. Thanks!

I looked at the infused-kim/zmk repo it doesn't seem to have the seeeduino_xiao_ble board defined at infused-kim/zmk/tree/sofle/app/boards/arm.

To get this working I need a seeeduino_xiao_ble compatible fork, or the original pr merged with the main repo. The split encoder pr is very old and would require a rebase with the current code changes.

Ignore the previous comment I was on the wrong branch on the infused-kim/zmk repo. Fixing that now both encoders seems to work correctly, you can check the details in the latest commit.

Thanks for looking again! I've made the changes you suggested, but my GH actions fail. I'm sure it's a typo I made...

Same type of error for all three artifacts. Am I missing the connection to my klein config repo?

Where do I define a type?

[snsten]

Replace the ZMK_SPLIT_ROLE_CENTRAL with ZMK_SPLIT_BLE_ROLE_CENTRAL in Kconfig.defconfig. It seems to be renamed from the docs but the dual encoder pr still uses the old name.

That change got it to build. How do I make sense of the errors to diagnose? Not very clear...

[idesignstuff]

ok, to get the right encoder to work too, I needed to add

CONFIG_EC11=y
CONFIG_EC11_TRIGGER_GLOBAL_THREAD=y

to klein_right.conf

With that change, they are both behaving. Thanks so much!
