## 板级配置
|
||||
## 板级配置(`Inc/board_config.h`)
|
||||
|
||||
编辑 `Inc/board_config.h` 可切换以下功能:
|
||||
所有功能开关和引脚定义集中在 `Inc/board_config.h`。功能开关均为单行数值宏:将右侧的 `ENABLE` 或 `DISABLE` 改为另一值即可;其中 `ENABLE` 为 `1`,`DISABLE` 为 `0`。以下为完整的宏开关说明和推荐使用方式。
|
||||
|
||||
### 功能开关速查表
|
||||
|
||||
| 宏 | 作用 | 默认值 | Release 建议 |
|
||||
|---|------|:---:|:---:|
|
||||
| `SOFTWARE_IIC` | I2C 实现方式 | `DISABLE`(硬件) | `DISABLE` |
|
||||
| `DEBUG_MODE` | printf 串口输出 | `DISABLE` | `DISABLE` |
|
||||
| `COM_DEBUG` | 命令帧调试打印 | `DISABLE` | `DISABLE` |
|
||||
| `DEBUG_VERBOSE` | 详细调试信息 | `DISABLE` | `DISABLE` |
|
||||
| `SEGGER_RTT_DETECTION` | SEGGER RTT 支持 | `ENABLE` | `DISABLE` |
|
||||
|
||||
---
|
||||
|
||||
### `SOFTWARE_IIC` — I2C 实现方式
|
||||
|
||||
选择 I2C 使用硬件外设还是软件 GPIO 模拟。
|
||||
|
||||
> 当前工程尚未实现 `SOFTWARE_IIC` 的条件编译驱动选择;该宏已迁移为数值配置,但改值不会在此版本切换 I2C 实现。
|
||||
|
||||
```c
|
||||
/* I2C 类型:软件 I2C 或 硬件 I2C */
|
||||
// #define SOFTWARE_IIC
|
||||
#undef SOFTWARE_IIC
|
||||
|
||||
/* 调试模式:开启 printf 输出 */
|
||||
// #define DEBUG_MODE
|
||||
#undef DEBUG_MODE
|
||||
|
||||
/* 调试详细模式:I2C 扫描等额外信息 */
|
||||
// #define DEBUG_VERBOSE
|
||||
#undef DEBUG_VERBOSE
|
||||
#define SOFTWARE_IIC DISABLE // DISABLE: 硬件 I2C(默认);ENABLE: 软件 I2C(GPIO 模拟)
|
||||
```
|
||||
|
||||
引脚定义集中在同一文件中,按需修改:
|
||||
| 选项 | 优点 | 缺点 |
|
||||
|------|------|------|
|
||||
| 硬件 I2C | DMA 支持、CPU 占用低 | 仅限固定引脚、调试复杂 |
|
||||
| 软件 I2C | 任意 GPIO、移植方便 | CPU 占用高、速率受限 |
|
||||
|
||||
> 切换后需同步修改下方 I2C 引脚定义。
|
||||

|
||||
### `DEBUG_MODE` — 调试模式
|
||||
|
||||
开启后 USART0 输出 printf 调试信息。**Release 固件必须关闭。**
|
||||
|
||||
```c
|
||||
#define DEBUG_MODE DISABLE // DISABLE: 关闭(默认);ENABLE: 开启调试输出
|
||||
```
|
||||
|
||||
**影响范围:**
|
||||
- 使能 `USART0` 初始化和 `printf` 重定向到串口
|
||||
- 会占用 PA2/PA3 引脚和 USART0 硬件资源
|
||||
- 增加 ROM 约 2~4KB(取决于 printf 调用量)
|
||||
|
||||
---
|
||||
|
||||
### `COM_DEBUG` — 命令帧调试打印
|
||||
|
||||
开启后串口命令解析过程打印每帧的详细内容(地址、长度、数据、校验)。**仅调试通信协议时开启。**
|
||||
|
||||
```c
|
||||
#define COM_DEBUG DISABLE // DISABLE: 关闭(默认);ENABLE: 开启命令帧调试
|
||||
```
|
||||
|
||||
**依赖:** 需要先开启 `DEBUG_MODE`,否则输出无法外发。
|
||||
|
||||
**输出示例:**
|
||||
```text
|
||||
[CMD] ADDR=01 LEN=05 DATA: AA BB CC DD EE CHK=OK
|
||||
```
|
||||
|
||||
> ⚠️ Release 必须关闭,否则大量串口输出会严重拖慢主循环。
|
||||
|
||||
---
|
||||
|
||||
### `DEBUG_VERBOSE` — 详细调试信息
|
||||
|
||||
在 `DEBUG_MODE` 基础上输出更底层的信息,如 I2C 总线扫描结果、MCU 型号识别等。
|
||||
|
||||
```c
|
||||
#define DEBUG_VERBOSE DISABLE // DISABLE: 关闭(默认);ENABLE: 开启详细调试
|
||||
```
|
||||
|
||||
**额外输出:**
|
||||
- 启动时打印 MCU Flash 容量检测结果
|
||||
- I2C 初始化时扫描总线上的设备地址
|
||||
- 其他诊断信息
|
||||
|
||||
> 依赖 `DEBUG_MODE`,开启后 ROM 进一步增加约 1~2KB。
|
||||
|

|
||||
|
||||
### `SEGGER_RTT_DETECTION` — SEGGER RTT 支持
|
||||
|
||||
RTT(Real-Time Transfer)是 SEGGER 的调试通道技术,通过 SWD 接口传输数据,不占用串口引脚,速度远超 UART。
|
||||
|
||||
```c
|
||||
#define SEGGER_RTT_DETECTION ENABLE // DISABLE: 禁用 RTT;ENABLE: 启用 RTT(默认)
|
||||
```
|
||||
|
||||
**启用时:**
|
||||
- 自动包含 `SEGGER_RTT.h`,提供 `RTT_printf` / `RTT_WriteString` / `RTT_PutChar` 宏
|
||||
- `SDK/SEGGER_RTT/` 模块参与编译和链接
|
||||
- 可用 J-Link RTT Viewer 或 VSCode + cortex-debug 查看实时日志
|
||||
|
||||
**禁用时:**
|
||||
- 应用层 RTT 头文件引用与调用代码均在预处理阶段排除
|
||||
- RTT 宏展开为空操作;应用目标不生成 RTT 调用代码
|
||||
- 为保持现有 CMake SDK 加载方式,`SDK/SEGGER_RTT/` 仍会参与构建;静态库中未被引用的对象不会被链接器提取
|
||||
|
||||
> **Release 建议关闭** — RTT 依赖调试器连接,量产固件中无意义且占用 ROM。
|
||||
|
||||
**依赖关系总览:**
|
||||
```
|
||||
COM_DEBUG ──── 依赖 ──→ DEBUG_MODE
|
||||
DEBUG_VERBOSE ─ 依赖 ──→ DEBUG_MODE
|
||||
SEGGER_RTT_DETECTION ─ 独立,与 DEBUG_MODE 并行
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 引脚定义
|
||||
|
||||
所有引脚宏集中在 `board_config.h` 尾部,按需修改:
|
||||
|
||||
```c
|
||||
/* I2C */
|
||||
#define I2C_SCL_PORT GPIOF
|
||||
#define I2C_SCL_PIN GPIO_PIN_1
|
||||
#define I2C_SDA_PORT GPIOF
|
||||
#define I2C_SDA_PIN GPIO_PIN_0
|
||||
|
||||
#define LED_PORT GPIOA
|
||||
#define LED_PIN GPIO_PIN_7
|
||||
/* LED */
|
||||
#define LED_RCU RCU_GPIOB
|
||||
#define LED_PORT GPIOB
|
||||
#define LED_PIN GPIO_PIN_1
|
||||
|
||||
/* UART */
|
||||
#define UART_GPIO_PORT GPIOA
|
||||
#define UART_TX_PIN GPIO_PIN_2
|
||||
#define UART_RX_PIN GPIO_PIN_3
|
||||
#define UART_BAUDRATE 115200U
|
||||
```
|
||||
|
||||
### MCU 型号自动检测
|
||||
|
||||
`board_config.c` 中的 `mcu_detect_and_config()` 上电自动识别 GD32E230 的 Flash 容量(F4=16K / F6=32K / F8=64K),结果存入全局变量 `g_mcu_flash_size`,并自动选择对应的 UART 外设(USART0 或 USART1)。
