How to change CONFIG_ZMK_COMBO_MAX_KEYS_PER_COMBO

[YHRen]

Hi @petejohanson

Thank you for the repo. Really enjoy the keyboard.
I think I'm hitting the limit of the default setting of CONFIG_ZMK_COMBO_MAX_KEYS_PER_COMBO=4.
I tried to add CONFIG_ZMK_COMBO_MAX_KEYS_PER_COMBO=6 to zaphod_defconfig file, but it does not seem to work.
Any advice on how to make such change?

Thank you so much!

I'm currently using the GH Actions following your tutorials. I'm not so sure how to set up a local environment. The west environment is new to me.

Hi, is there any update on this? I currently experiment with combo with the following positions: (1,2), (2,3), (1,3) and (1,2,3) but so far the (1,2,3) combo doesn't work.

Solved it in the GH Adtions build by adding the following step. Other configs can be modified in the similar way.

     - name: List modules (west list)
        run: west list

      - name: update max combos per key
        run: ln="$(($(sed -n '/ZMK_COMBO_MAX_COMBOS_PER_KEY/=' zmk/app/Kconfig)+2))"; sed -i "${ln}s/default \([0-9]*\)/default 16/" zmk/app/Kconfig

      - name: Build Zaphod (west build)
        run: west build -s zmk/app -b zaphod -d build/zaphod -- -DZMK_CONFIG="${GITHUB_WORKSPACE}/config"
