Lily58 Build Notes

Firmware

Firmware Setup Procedure

1. Clone and make a new branch.
2. Make a new keymap: qmk new-keymap -kb lily58/rev1
3. Navigate to keyboards/lily58/keymaps/DeflateAwning/config.h
4. Open the rules.mk file at that location.
5. Paste in the magic line (into rules.mk): CONVERT_TO = rp2040_ce
6. Build with qmk compile -kb lily58/rev1 -km DeflateAwning
7. Flash by copying the .uf2 file to the board.

Flashing Notes

• Short the BOOT pad to the closest edge pad (GND), then do a reset.
• After the first QMK flash, you can double-click the reset switch (within 200ms) to enter flashing mode.

Handedness Configuration

// Enable storing the left vs. right hand layout in EEPROM.
// Add the `-bl` flag when flashing, per https://docs.qmk.fm/features/split_keyboard#handedness-by-eeprom

Assembly Notes

• To solder pins onto MCU, offset away from the USB-C connector. Don't assemble the top pins (1 row) beside the USB-C connector.
• On the right half, put the MCU (with components facing down, installed from the top) offset to the right/offset toward the switches.
• On the left half, put the MCU (with components facing down, installed from the top) offset to the right/away from the switches.
• Close/short/jump the bad underneath the MCU.
• Install reset switch and TRRS connector on top side of each board.
