 # Changelog

+## 2026-10-25 — 3.5" backlight pin correction
+
+- `cyd_35r`: `TFT_BL` / `TFT_BL_PIN` **GPIO27** (was wrongly 21; 21 is GT911 INT).
+- `../CYD_PROJECT_GUIDE.md` §A：2.8 vs 3.5 对照（触控 2046/911、背光、外设脚 22/27 vs 22）。
+
+## 2026-10-18 — Pomodoro presets + custom minutes
+
+- Duration presets: 1 / 3 / 5 / 10 minutes; `Set` opens numeric keypad (1–99).
+- Keep `+/-`, Start/Pause/Reset, sound picker, speaker + volume.
+
+## 2026-10-18 — Pomodoro timer UI
+
+- Tag baseline `v1.0-beep-wav` (Beep + WAV list UI).
+- New Pomodoro screen with Start/Pause/Reset and selectable alarm sound.
+- Keep speaker toggle + volume slider; TF status in header.
+
 ## 2026-10-18 — WAV via DAC2 only (touch-safe)

 - Drop I2S INTERNAL_DAC (it enables GPIO25 and kills touch).

 ## 功能

- SoftSPI 触摸（已标定，勿改 `src/touch.cpp` 映射）
- TF 卡信息（VSPI）
- 喇叭 GPIO26，默认音量 **20%**；按钮：Speaker ON/OFF、Play Music
+- SoftSPI 触摸（2.8，已标定，勿改 `src/touch.cpp` 映射）；3.5C 为 GT911 I2C
+- 番茄钟：预设 1 / 3 / 5 / 10 分钟；`Set` 自定义输入；`+/-` 微调；Start / Pause / Reset
+- 结束音效：内置 Beep 列表自选（默认 Alarm），点名称可试听
+- 喇叭 GPIO26 + 音量滑条；TF 卡状态显示在右上角
+- 基线标签：`v1.0-beep-wav`（改番茄钟前的 Beep + WAV 界面）
