Android i2c-tools移植

一、下载I2C-tools工具：

最近在移植i2c-tools工具，下载地址：https://i2c.wiki.kernel.org/index.php/I2C_Tools；百度到了wiki中的git地址；

  git clone git://git.kernel.org/pub/scm/utils/i2c-tools/i2c-tools.git -b i2c-tools-3.1

二、将git下载到external目录下，编写Android.mk，将其打包system.img：

Android.mk内容如下：

 LOCAL_PATH:= $(call my-dir)

 include $(CLEAR_VARS)

 LOCAL_MODULE_TAGS := optional
 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include
 LOCAL_SRC_FILES := tools/i2cbusses.c tools/util.c
 LOCAL_MODULE := i2c-tools
 include $(BUILD_STATIC_LIBRARY)

 include $(CLEAR_VARS)

 LOCAL_MODULE_TAGS := optional
 LOCAL_SRC_FILES:=tools/i2cdetect.c
 LOCAL_MODULE:=i2cdetect
 LOCAL_CPPFLAGS += -DANDROID
 LOCAL_SHARED_LIBRARIES:=libc
 LOCAL_STATIC_LIBRARIES := i2c-tools
 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include
 include $(BUILD_EXECUTABLE)

 include $(CLEAR_VARS)

 LOCAL_MODULE_TAGS := optional
 LOCAL_SRC_FILES:=tools/i2cget.c
 LOCAL_MODULE:=i2cget
 LOCAL_CPPFLAGS += -DANDROID
 LOCAL_SHARED_LIBRARIES:=libc
 LOCAL_STATIC_LIBRARIES := i2c-tools
 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include
 include $(BUILD_EXECUTABLE)

 include $(CLEAR_VARS)

 LOCAL_MODULE_TAGS := optional
 LOCAL_SRC_FILES:=tools/i2cset.c
 LOCAL_MODULE:=i2cset
 LOCAL_CPPFLAGS += -DANDROID
 LOCAL_SHARED_LIBRARIES:=libc
 LOCAL_STATIC_LIBRARIES := i2c-tools
 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include
 include $(BUILD_EXECUTABLE)

 include $(CLEAR_VARS)

 LOCAL_MODULE_TAGS := optional
 LOCAL_SRC_FILES:=tools/i2cdump.c
 LOCAL_MODULE:=i2cdump
 LOCAL_CPPFLAGS += -DANDROID
 LOCAL_SHARED_LIBRARIES:=libc
 LOCAL_STATIC_LIBRARIES := i2c-tools
 LOCAL_C_INCLUDES += $(LOCAL_PATH) $(LOCAL_PATH)/$(KERNEL_DIR)/include
 include $(BUILD_EXECUTABLE)

然后mm命令编译当前目录，生成到：

make snod编译进板子上的system/bin目录下；

Android下的i2c-tools使用如链接所示，就不提及了；
