+
+## Project Overview
+
+This is an **STM32F103C8T6** embedded C project using **STM32CubeMX** code generation.
+The project implements a LoRa module (E32-TTL-433) control system with USB CDC communication,
+OLED display (u8g2), and a menu system.
+
+## Build System
+
+- **IDE**: Keil MDK-ARM V5.32
+- **Linker**: GCC
+- **Project File**: `project.ioc` (STM32CubeMX configuration)
+- **No standard build system** (Makefile/CMake) - build via Keil uVision or re-generate with CubeMX
+
+**To rebuild**:
+1. Open `project.ioc` in STM32CubeMX
+2. Click "Generate Code"
+3. Open the generated project in Keil uVision
+4. Build using Keil's build system
+
+There is **no test framework** - this is a bare-metal embedded project without unit tests.
+
+## Code Style Guidelines
+
+### Naming Conventions
+- **Functions**: `snake_case` (e.g., `e32_hal_uart_tx`, `Menu_Init`)
+- **Variables**: `snake_case` (e.g., `usb_rx_data`, `my_usb_rx_num`)
+- **Constants/Defines**: `UPPER_SNAKE_CASE` (e.g., `GPIO_PIN_RESET`, `E32_USE_GPIO_AUX`)
+- **Types/Enums**: `snake_case_t` suffix for types (e.g., `key_name_t`, `work_mode_t`)
+- **Pin Defines**: Follow CubeMX pattern (e.g., `RESET_Pin`, `AUX_GPIO_Port`)
+
+### File Organization
+```
+Core/Src/          - Main application source (main.c, gpio.c, usart.c, etc.)
+Core/Inc/          - Main application headers
+Middlewares/       - Third-party libraries (u8g2, MultMenu, USB)
+USB_DEVICE/       - USB CDC implementation
+docs/             - Documentation
+```
+
+### Code Structure
+- Use **HAL library** for peripheral access (e.g., `HAL_UART_Transmit`, `HAL_GPIO_ReadPin`)
+- Follow **CubeMX USER CODE blocks** - place custom code between `/* USER CODE BEGIN ... */` and `/* USER CODE END ... */`
+- Keep hardware-specific code in `Core/Src/` (e.g., `e32_hal.c`, `u8g2_hal.c`)
+- Keep application logic separate from HAL
+
+### Formatting
+- Use **tabs** for indentation (consistent with generated CubeMX code)
+- Opening brace on same line as function declaration
+- Maximum line width: ~120 characters (follow existing style)
+- No enforced code formatter - maintain consistency with surrounding code
+
+### Comments
+- Use **Doxygen-style** function comments:
+  ```c
+  /**
+   * @brief  Brief description
+   * @param  param_name Description
+   * @retval Return value description
+   */
+  ```
+- Chinese comments are acceptable (project uses mixed EN/ZH)
+- Comment complex logic, not trivial code
+
+### Error Handling
+- Use `Error_Handler()` (defined in main.c) for fatal errors
+- Check HAL return values for UART, I2C, USB operations
+- Implement timeout mechanisms for blocking operations
+- Use `HAL_Delay()` for timing-critical operations
+
+### Includes
+- Group includes: standard library, HAL, application-specific
+- Use include guards in headers (`#ifndef __FILE_H`, `#define __FILE_H`)
+- Use `extern "C"` guards when mixing C/C++ headers
+
+### Types and Constants
+- Use stdint types (`uint8_t`, `uint16_t`, `uint32_t`) for portability
+- Prefer `bool` over `uint8_t` for boolean values (include `<stdbool.h>`)
+- Define magic numbers as constants or enums
+
+## Important Notes
+
+1. **Never modify auto-generated code** outside USER CODE sections - it will be overwritten by CubeMX
+2. **Preserve the project.ioc** - this is the single source of truth for hardware configuration
+3. **USB CDC** uses `usbd_cdc_if.c` for custom implementation
+4. **Menu system** uses MultMenu middleware in `Middlewares/MultMenu/`
+5. **Display driver** uses u8g2 in `Middlewares/u8g2Lib/`
+

+
+## Project Overview
+
+This is an STM32F103C8 firmware project for the E32-433TBH-SC 433MHz wireless transceiver module with OLED display and menu system. The project provides a user interface for configuring and testing the E32 wireless module.
+
+## Build System
+
+This project uses Keil MDK-ARM (µVision) for building.
+
+**Build Commands:**
+- Open `MDK-ARM/project.uvprojx` in Keil µVision
+- Build: F7 or Project → Build Target
+- Flash: F8 or Flash → Download
+
+**Target:** STM32F103C8 (Cortex-M3, 64KB Flash, 20KB RAM)
+
+## Architecture
+
+### Hardware Abstraction Layer (`Core/`)
+- **e32_hal.c/h** - Hardware abstraction for the E32 wireless module
+  - `e32_hal_uart_tx()` - UART transmission
+  - `e32_hal_aux_wait()` - Wait for AUX pin (module busy indicator)
+  - `e32_hal_reset()` - Reset the E32 module
+  - `e32_hal_work_mode()` - Switch between transparent/WOR/config modes
+
+- **e32_demo.c/h** - E32 module driver and protocol implementation
+  - Register structures for module configuration (address, channel, baud rate, power, FEC)
+  - Functions for reading module name, firmware version, configuration
+  - Transmission modes (transparent, specify target)
+
+- **u8g2_hal.c/h** - Hardware interface for OLED display via I2C
+- **key.c** - Button input handling (UP, DOWN, ENTER)
+- **fifo.c** - Ring buffer implementation for UART/USB data
+- **systick.c** - 1ms timer callbacks for timeouts and key scanning
+
+### Menu System (`Middlewares/MultMenu/`)
+A custom hierarchical menu framework with animation support:
+
+- **menu.c/h** - Core menu framework
+  - `Menu_Init()` - Initialize menu structure
+  - `Menu_Task()` - Main menu loop (call from main while loop)
+  - Page/Item/Menu structures for hierarchical navigation
+
+- **menuConfig.h** - Menu configuration and type definitions
+  - Screen resolution: 128x64 (OLED)
+  - Menu states: INIT, DRAWING, RUN, APP_RUN, etc.
+  - Item types: PARENTS, LOOP_FUNCTION, ONCE_FUNCTION, SWITCH, DATA
+
+- **application.c/h** - Application-specific menu callbacks
+  - Configuration items: work_mode, rate_mode, channel, tx_power, tx_count
+  - Mode callbacks: tx_mode_callback, rx_mode_callback
+  - Utility callbacks: version_callback, reset_callback, background_color_callback
+
+- **AirPlane.c/h, DinoGame.c** - Example games running on the menu system
+
+### Display Library (`Middlewares/u8g2Lib/`)
+U8g2 graphics library for OLED display:
+- Configure display in `u8g2_hal.c`
+- Font: `u8g2_font_profont12_mf` (12px height, defined in menuConfig.h)
+
+### USB CDC (`USB_DEVICE/`)
+Virtual serial port over USB for PC communication and AT commands.
+
+## Key Configuration
+
+### Pin Definitions (`Core/Inc/main.h`)
+```
+RESET  -> PA3  (E32 module reset)
+M0     -> PA7  (Mode select 0)
+M1     -> PB0  (Mode select 1)
+AUX    -> PB1  (Busy indicator)
+LED_TX -> PA15 (TX indicator)
+LED_RX -> PB6  (RX indicator)
+KEY_UP    -> PB4
+KEY_DOWN  -> PB9
+KEY_ENTER -> PB7
+```
+
+### E32 Work Modes
+- Mode 0 (M0=0, M1=0): Transparent transmission
+- Mode 1 (M0=1, M1=0): WOR master (wake on radio)
+- Mode 2 (M0=0, M1=1): WOR slave (power saving)
+- Mode 3 (M0=1, M1=1): Configuration/sleep mode
+
+### E32 Register Structure
+- Register 01H-02H: Module address (high/low byte)
+- Register 03H: Air data rate, UART baud rate, parity
+- Register 04H: RF channel
+- Register 05H: TX power, FEC, WOR period, target mode
+
+## Adding New Menu Items
+
+1. Define the item variable in `menu.c`:
+   ```c
+   xItem my_new_item;
+   ```
+
+2. Add page if needed:
+   ```c
+   xPage my_new_page;
+   ```
+
+3. In `Menu_Init()`, add the item using `AddItem()`:
+   ```c
+   AddItem("Item Name", ITEM_TYPE, &data, &my_new_item, &Home_Page, NULL, my_callback);
+   ```
+
+4. Implement the callback function in `application.c`:
+   ```c
+   void my_callback(xpItem item) {
+       // Handle item selection
+   }
+   ```
+
+## STM32CubeIDE Integration
+
+The project was generated with STM32CubeMX (`project.ioc`). To modify peripherals:
+1. Open `project.ioc` in STM32CubeMX
+2. Configure peripherals
+3. Generate code
+4. Copy generated files to `Core/` directory, preserving user code sections marked by `/* USER CODE BEGIN */` and `/* USER CODE END */`
+
+## Important Notes
+
+- The main loop calls `Menu_Task()` to handle menu rendering and input
+- Key scanning happens via 1ms systick callback
+- Use `usb_printf()` for debug output via USB CDC
+- AUX pin must be HIGH before sending commands (use `e32_hal_aux_wait()`)
+- E32 module reset takes ~30ms (V8.2 firmware) or ~1200ms (V8.1 firmware)

+  * @author  MCD Application Team
+  * @brief   CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
+  * 
+  * 1.  This file provides two functions and one global variable to be called from 
+  *     user application:
+  *      - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
+  *                      factors, AHB/APBx prescalers and Flash settings). 
+  *                      This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32f1xx_xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick 
+  *                                  timer or configure other parameters.
+  *                                     
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32f1xx_xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depending on
+  *    the product used), refer to "HSE_VALUE". 
+  *    When HSE is used as system clock source, directly or through PLL, and you
+  *    are using different crystal you have to adapt the HSE value to your own
+  *    configuration.
+  *
