Dan's QMK Userspace

External QMK userspace for Dan's keyboards.

Keymaps

• sofle/rev1:ddyo
• bastardkb/charybdis/4x6/splinktegrated_rev1:ddyo

Charybdis changes

The ddyo keymap adapts an older Elite-C Charybdis shield to a Sea-Picro/Splinky RP2040 controller:

• Custom left/right matrix maps use the bottom GP12-GP16 pins, freeing GP26 for the optional FSR and GP21 for trackball CS.
• Handedness on GP27 and USB VBUS detection on GP19.
• The optional GP26 FSR has configurable thresholds, scan timing, and console diagnostics.
• Elite-C pin names map to the RP2040 controller so the old shield wiring still works.

Modules

Pinned as Git submodules:

• bastardkb/argos, using Dan's fork until its changes are upstream
• srwi/keypeek_layer_notify

Flash

git submodule update --init --recursive
qmk flash -kb sofle/rev1 -km ddyo
qmk flash # guarded Charybdis backup + both halves + restore

The Charybdis flash task waits for the normal right/trackball half, saves and commits an Argos-compatible JSON backup, flashes the right half and then the left half, then waits for the right half again to restore and verify Argos. A failed backup or commit aborts before QMK runs, and the task does not finish until restoration succeeds.

qmk flash            # backup, flash both halves, restore, verify
mise run flash       # alias: mise run qf
mise run flash-right # alias: mise run qfr
mise run flash-left  # alias: mise run qfl
mise run backup      # alias: mise run qb

The current backup is kept beside the keymap at keyboards/bastardkb/charybdis/4x6/keymaps/ddyo/argos.json. Every successful changed backup commits only that file as chore: update Argos backup; unchanged backups do not create empty commits. Unrelated staged and working-tree changes are left untouched. A custom --output must already be tracked inside this repository so the same safety guarantee applies. Close Argos and KeyPeek if another app consumes the Raw HID replies during backup. Use ./bin/flash-charybdis --no-backup only as an explicit emergency bypass.

Mise prepends a repository guard for qmk. In this userspace, qmk flash and an explicit Charybdis qmk flash -kb ... -km ddyo both route to the backup-first wrapper. Normal QMK commands and flashes for other keyboards pass through. The wrapper applies a scoped bypass only after the Argos export succeeds. It starts each compile without an input prompt and checks USB/HID state while waiting for the required half. Physical-half detection belongs to the ddyo keymap, not the Argos module. It uses VIA's custom-get-value request 08 00 DD and returns 1 for right or 0 for left at response offset 3. argosctl uses that keymap response for the wrapper's --require-right-half backup and restore guards.
