## 2026-10-17 — SoftSPI touch + LVGL inverse (fix mux)
|
||
|
||
- VSPI remux broke SD mount and froze touch at raw(0,4095).
|
||
- Touch back to SoftSPI on 25/32/39/33; SD keeps exclusive VSPI 18/19/23/5.
|
||
- Same temperature UI map, then invert LVGL ROTATION_270 for button hits.
|
||
|
||
## 2026-10-17 — Touch = temperature driver + LVGL inverse
|
||
|
||
- Attempted XPT2046 HW SPI + VSPI pin mux; superseded (broke SD/touch).
|
||
|
||
## 2026-10-17 — Touch calib from COM3 logs
|
||
|
||
- Logged live `Touch phys/logic` on COM3; inverted physical X so bottom matches UI.
|
||
- On-screen `Touch L:x,y` debug; larger 150×60 buttons.
|
||
- Verified Speaker ON/OFF via serial during capture.
|
||
|
||
## 2026-10-17 — Fix touch Y (buttons dead zone)
|
||
|
||
- Root cause: feeding already-landscape 320x240 points while LVGL also applies
|
||
ROTATION_270 (double transform) → only upper ~1/3 hit-tested correctly.
|
||
- Fix: report physical 240x320 coords; let LVGL rotate (matches `lv_indev.c`).
|
||
|
||
## 2026-10-17 — Restore LVGL touch
|
||
|
||
- SoftSPI + LVGL `lv_indev` (with `lv_indev_set_display`).
|
||
- Larger clickable speaker/play buttons.
|
||
|
||
## 2026-10-17 — Fix touch offset
|
||
|
||
- SoftSPI touch now uses the same rotation=2 transform + map as `temperature`.
|
||
- (Pressure-only path was too strict; superseded by restore above.)
|
||
|
||
## 2026-10-17 — Prebuilt firmware folder
|
||
|
||
- Add `firmware/cyd/` with bin + `flash.ps1` / `flash.bat` (same pattern as temperature).
|
||
- Add `firmware/export_from_build.ps1` to refresh archived binaries after builds.
|
||
- Track `firmware/**/*.bin` in git; document flash-without-compile in README.
|
||
|
||
## 2026-10-17 — Touch speaker control + music
|
||
|
||
- SoftSPI XPT2046 touch (GPIO 32/39/25/33/36), coexists with SD.
|
||
- LVGL buttons: **Speaker ON/OFF**, **Play Music / Stop**.
|
||
- Non-blocking built-in melody (Twinkle Twinkle); no auto beeps.
|
||
- Docs updated.
|
||
|
||
## 2026-10-17 — Speaker audio test
|
||
|
||
- Add GPIO26 speaker path (onboard SC8002B amp / P4 connector).
|
||
- (Superseded by touch control above.)
|
||
|
||
## 2026-10-17 — Initial
|
||
|
||
- CYD TF/microSD mount (VSPI) + LVGL storage info UI.
