From ceb1306308f46eb97646a3b1c2ffe4456834ffa3 Mon Sep 17 00:00:00 2001 From: "Peter J. A. Cock" Date: Thu, 12 Jun 2025 14:07:14 +0900 Subject: [PATCH] Setup new keyboard definition for tutte_coxeter_36e MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ❯ qmk new-keyboard -kbtutte_coxeter_c36e -n "Peter J. A. Cock" -u peterjc -t RP2040 -l split_3x5_3 Ψ Generating a new QMK keyboard directory Ψ Created a new keyboard called tutte_coxeter_36e. Ψ Build Command: qmk compile -kb tutte_coxeter_36e -km default. Ψ Project Location: /Users/peterjc/repositories/qmk_firmware/keyboards/tutte_coxeter_36e. Ψ Now update the config files to match the hardware! ❯ mv ~/repositories/qmk_firmware/keyboardstutte_coxeter_36e ~/repositories/qmk_userspace/keyboards Note it did not want to accept hyphens, so used underscores. Then define sparse 13x13 scanning matrix of 36 edge / 26 vertice graph, using the RP2040 GPIO pin names. i.e. The partial Tutte-Coxeter graph, using RP2040 GPIO pin names. --- keyboards/tutte_coxeter_36e/keyboard.json | 96 +++++++++++++++++++ .../keymaps/default/keymap.c | 27 ++++++ keyboards/tutte_coxeter_36e/readme.md | 32 +++++++ 3 files changed, 155 insertions(+) create mode 100644 keyboards/tutte_coxeter_36e/keyboard.json create mode 100644 keyboards/tutte_coxeter_36e/keymaps/default/keymap.c create mode 100644 keyboards/tutte_coxeter_36e/readme.md diff --git a/keyboards/tutte_coxeter_36e/keyboard.json b/keyboards/tutte_coxeter_36e/keyboard.json new file mode 100644 index 00000000..1f062f58 --- /dev/null +++ b/keyboards/tutte_coxeter_36e/keyboard.json @@ -0,0 +1,96 @@ +{ + "manufacturer": "Peter J.
