本文介绍如何进行mmc5603x磁传感器的驱动移植工作，包括更新内核配置文件及驱动文件，并针对android 8.1及以上版本介绍了新的校准库使用方式及在device.mk中的配置方法。

1.驱动移植

A update/alps/kernel-4.4/drivers/misc/mediatek/sensors-1.0/magnetometer/Kconfig

A update/alps/kernel-4.4/drivers/misc/mediatek/sensors-1.0/magnetometer/Makefile

A update/alps/kernel-4.4/drivers/misc/mediatek/sensors-1.0/magnetometer/mmc5603x/Kconfig

A update/alps/kernel-4.4/drivers/misc/mediatek/sensors-1.0/magnetometer/mmc5603x/Makefile

A update/alps/kernel-4.4/drivers/misc/mediatek/sensors-1.0/magnetometer/mmc5603x/mmc5603x.c

A update/alps/kernel-4.4/drivers/misc/mediatek/sensors-1.0/magnetometer/mmc5603x/mmc5603x.h

2.android8.1之后mesensor不再跑deamon，而是用校准库，放到vendor任意位置

A update/alps/vendor/microhand/msensor/mmc5603x_32bit/libmemsicd5603x.so

A update/alps/vendor/microhand/msensor/mmc5603x_64bit/libmemsicd5603x.so

3.在device.mk中做拷贝动作

update/alps/device/mediateksample/k39tv1_bsp_1g/device.mk

+#add by msensor mmc5603x
+#PRODUCT_COPY_FILES += vendor/microhand/msensor/mmc5603x_64bit/libmemsicd5603x.so:vendor/lib/libmemsicd5603x.so
+PRODUCT_COPY_FILES += vendor/microhand/msensor/mmc5603x_32bit/libmemsicd5603x.so:vendor/lib/libmemsicd5603x.so
