commit 9576c5f7d2ca384c95f2da17e9316694c76f06ac
Author: DESKTOP-PUHFO60\dsx2016 <evan199101@gmail.com>
Date:   Fri Oct 23 14:08:51 2026 +0800

    Add HW-069 v1.1 4-digit TM1637 test with SoftSPI touch and LVGL.
    
    CLK on GPIO22, DIO on GPIO27; value/brightness/colon controls and flashable firmware/cyd package.

+# HW-069 四位数显（CYD）
+
+触控 + LVGL 参考 `tftest` / `hw269test`。HW-069 v1.1（TM1637）两线驱动：调数值、亮度、冒号、开关。
+
+## 硬件
+
+| 项目 | 说明 |
+|------|------|
+| 板子 | CYD ESP32-2432S028R |
+| 模块 | HW-069 v1.1 四位 0.36" 数码管（TM1637） |
+| CLK | **GPIO22** |
+| DIO | **GPIO27** |
+
+接线：
+
+| HW-069 | CYD |
+|--------|-----|
+| VCC | 3.3V 或 5V |
+| GND | GND |
+| CLK | GPIO22 |
+| DIO | GPIO27 |
+
+## 操作
+
+- 大字：当前显示值（冒号开时显示 `mm:ss` 样式）
+- **-100 / -1 / +1 / +100**：改数值（0–9999）
+- 滑条：亮度 0–100%（映射 TM1637 8 档）
+- **Colon**：中间冒号开关
+- **Display ON/OFF**：熄灭 / 点亮数显
