Detailed Description

HPM I2C 主机驱动适配头文件 / Adapter header for the HPM I2C master driver.

本文件在 HPM SDK hpm_i2c_drv 之上实现 LibXR I2C 抽象，覆盖 blocking 字节流、寄存器地址式传输、可选 DMA helper 后台路径，以及 ADDRHIT、CMPL 等关键主机状态的错误映射。多系列兼容依赖 HPMSOC_HAS_HPMSDK_I2C、 __has_include("hpm_i2c_drv.h")、实例/IRQ/DMA request header 宏和 I2C_SOC_TRANSFER_COUNT_MAX 等 SDK 限制宏；硬件时序和 bus recovery 仍待上板验证。

This file implements the LibXR I2C abstraction on top of the HPM SDK hpm_i2c_drv APIs, covering blocking byte-stream transfers, register-address transfers, an optional DMA-helper background path, and error mapping for key master states such as ADDRHIT and CMPL. Multi-series compatibility relies on HPMSOC_HAS_HPMSDK_I2C, __has_include("hpm_i2c_drv.h"), instance/IRQ/DMA request header macros, and SDK limit macros such as I2C_SOC_TRANSFER_COUNT_MAX; hardware timing and bus recovery still require board validation.
