# SoC 能力宏

[English]

不同型号的 ESP 芯片内部会集成不同的硬件模块。哪怕是同一种模块，在不同的芯片上也可能具有细微的差异。ESP-IDF 中提供了一份小型的“数据库”来描述不同芯片之间的差异（注意，我们不描述共性，只描述差异）。这份“数据库“的内容以宏定义的形式定义在 soc/soc_caps.h 文件中，我们称之为 SoC 能力宏。用户可以通过在代码中使用条件编译指令（比如 `#if`）来使用这些宏，从而控制实际需要编译的代码内容。

备注

请注意， soc/soc_caps.h 中的内容目前还不稳定，未来可能会发生重大更改。

## 使用 SoC 能力宏

我们推荐通过下面的宏函数来间接地访问 SoC 能力宏：

宏函数 | 描述 | 示例
--- | --- | ---
`SOC_IS` | 判断芯片型号 | `#if SOC_IS(ESP32)` 判断是否为 ESP32 芯片
`SOC_HAS` | 判断芯片是否具有某个硬件模块或功能 | `#if SOC_HAS(DAC)` 判断是否具有 DAC 模块

- components/soc/include/soc/soc_caps_eval.h

- This header file can be included with:

  >     #include "soc/soc_caps_eval.h"

### Macros

_SOC_CAPS_EVAL(_name)

  SOC Capability evaluation helpers

  These macros provide a standardized way to query SOC capabilities without directly accessing the macros in soc_caps.h.

  The main categories of macros are:

  - SOC_IS : Check if the SOC is a specific target (e.g., SOC_IS(ESP32S3))

  - SOC_MODULE_ATTR : Get a specific attribute of a module (e.g., SOC_MODULE_ATTR(GPTIMER, NUM))

  - SOC_MODULE_SUPPORT : Check if a module supports a feature (e.g., SOC_MODULE_SUPPORT(GPTIMER, ETM))

SOC_HAS(_module)

SOC_IS(_target)

SOC_MODULE_ATTR(_module, _attr)

SOC_MODULE_SUPPORT(_module, _feat)
