MeshCore-Solo/solo/wio-tracker-l1-eink/platformio.ini

; Solo build for Seeed Wio Tracker L1 (E-ink) -- extends WioTrackerL1Eink,
; defined in variants/wio-tracker-l1-eink/platformio.ini. Solo configs live in
; their own top-level solo/ folder, separate from the shared upstream board
; variants in variants/, so this repo's Solo-specific additions don't get
; mixed in with configs other MeshCore forks/upstream also carry.
;
; Two builds for the 2.13" panel, one per orientation: each screen is laid out
; for one shape, and Settings > Rotation only turns it upside down. Landscape
; writes in the 8x13 font at the panel's own resolution (EINK_LARGE_FONT);
; portrait keeps the 6x9, whose narrow width wants the smaller cell. The
; joystick reads upright with the panel at rotation 1 (landscape) and turns
; with it (JOYSTICK_UPRIGHT_ROTATION). A third for a 4.2" 400x300 panel on the
; same wiring, in the 9x15.
;
; All: Dual BLE+USB with added Solo.

; Optimise for size, not speed: the nRF52 Arduino core defaults to -Ofast
; (≈ -O3 + -ffast-math), which bloats flash by ~200 KB on this feature-rich
; solo build. -Os keeps every feature, fits comfortably, and is actually safer
; for float (no fast-math reassociation). Speed is irrelevant for the UI/mesh.
; The offline queue (messages held for the phone app while it's away) at 128,
; not the board's 256: on the nRF52 the 256 x 177 B left ~5 KB of heap next to
; the on-device UI (which keeps its own history), too little for a sign buffer.
