Corne 42 custom pinkie buttons per layer, ZMK

[dpeley]

I have been searching for over a week to try and find this answer, so I'm sorry if it's somewhere obvious. I'm trying to create a custom mapping for the Miryoku ZMK custom_config file to let me map the extra pinkie keys on the Corne 6 column (42 key) differently per layer. Can anyone point me in the right direction for that?

See the To change the mapping per layer paragraph in the custom_config.h / Mapping / Miryoku ZMK section at #85. Also see the For complete examples, see example custom_config.h shared by members of the community link there.

E.g to map the left hand top row outer pinkie column key on the Tap layer to Escape:

#if defined (MIRYOKU_KEYBOARD_CORNE)

#define XXX &none

#define MIRYOKU_LAYERMAPPING_TAP( \
     K00, K01, K02, K03, K04,      K05, K06, K07, K08, K09, \
     K10, K11, K12, K13, K14,      K15, K16, K17, K18, K19, \
     K20, K21, K22, K23, K24,      K25, K26, K27, K28, K29, \
     N30, N31, K32, K33, K34,      K35, K36, K37, N38, N39 \
) \
&kp ESC K00  K01  K02  K03  K04       K05  K06  K07  K08  K09  XXX \
XXX  K10  K11  K12  K13  K14       K15  K16  K17  K18  K19  XXX \
XXX  K20  K21  K22  K23  K24       K25  K26  K27  K28  K29  XXX \
               K32  K33  K34       K35  K36  K37

#endif

Here is another example of a custom per layer mapping: #158.

That looks ok.

You can verify that the file is being used by adding #error somewhere inside the if / endif block.

Also check that you are flashing the files downloaded from the workflow build, as it's easy to accidentally flash the wrong file, and that the board resets itself after flashing.

I've been deleting all the files after trying, so no danger of using the wrong one, yes the board resets afterwards, and when I tried building again with the #error, it stated this:

/__w/DanCrkbd5ZmkMiryoku/DanCrkbd5ZmkMiryoku/miryoku_zmk/config/../miryoku/custom_config.h:6:2: error: #error 6 | #error | ^~~~~ CMake Error at /__w/DanCrkbd5ZmkMiryoku/DanCrkbd5ZmkMiryoku/zmk/zephyr/cmake/modules/extensions.cmake:3885 (message): failed to preprocess devicetree files (error code 1):

Thank you for your patience and all your hard work on this wonderful layout

Actually, now that I think about it, I know for sure that this first build was used and successfully flashed, cause the key map on the corne was previously qwerty before flashing, and the one that I built with the custom_config file was the default (colemakDH). The Colemak was successfully mapped, but the pinkies weren't.

Sorry, my example was bad. It should have been MIRYOKU_LAYERMAPPING_TAP! I'll correct it in the original comment.

[dpeley]

This did it! Thank you so much!
