 # EPD-nRF5
 
-墨水屏日历固件，支持农历、节气、节假日调休显示，也可以通过蓝牙传输图像到墨水屏作为相框使用。日历界面已适配常见的 4.2 寸和 7.5 寸墨水屏分辨率，且同一个固件可驱动不同尺寸屏幕（可通过上位机在线切换屏幕尺寸和驱动）。
+E-paper display calendar firmware with support for Chinese lunar calendar, solar terms, and holiday schedules. It can also transmit images via Bluetooth to the e-paper display for use as a digital photo frame. The calendar interface is adapted for common 4.2-inch and 7.5-inch e-paper resolutions, and the same firmware can drive different screen sizes (screen size and driver can be switched online through the web interface).
 
-支持的主控芯片有： `nrf51822` / `nrf51802` / `nrf52811` / `nrf52810`，墨水屏方面支持常见的 `UC81xx` / `SSD16xx` 系列驱动（黑白/三色/四色），同时还支持自定义墨水屏到 MCU 的引脚映射，支持睡眠唤醒（NFC / 无线充电器），支持蓝牙 OTA 固件升级。
+Supported MCUs: `nrf51822` / `nrf51802` / `nrf52811` / `nrf52810`. For e-paper displays, it supports common `UC81xx` / `SSD16xx` series drivers (black & white / 3-color / 4-color). It also supports custom pin mapping from the e-paper display to the MCU, sleep/wake functionality (NFC / wireless charger), and Bluetooth OTA firmware updates.

-上位机支持多种图片抖动算法，且可以对图片进行涂鸦、添加文字。除了显示图片作为电子相框外，还可以切换到日历模式，显示月历、农历节气、节假日、放假调休等信息。
+The web interface supports multiple image dithering algorithms and allows you to doodle on images and add text. In addition to displaying images as a digital photo frame, it can also switch to calendar mode to display monthly calendars, Chinese lunar calendar solar terms, holidays, and work schedule adjustments.

-修改 GUI 目录下的代码后，重新执行上面的 make 命令编译即可。
+After modifying the code in the GUI directory, simply re-execute the make command above to compile.
 
-> **注意:** GUI 目录下的代码不可依赖平台相关的东西，比如单片机特有的 API 接口，否则在 Windows 下编译会失败。正确的做法是：在调用 `DrawGUI` 函数前就把数据算好并放到 `gui_data_t` 里，然后通过 `data` 参数传进去。
+> **Note:** Code in the GUI directory must not depend on platform-specific things, such as microcontroller-specific API interfaces, otherwise compilation on Windows will fail. The correct approach is: calculate the data and put it in `gui_data_t` before calling the `DrawGUI` function, then pass it in through the `data` parameter.
