动态配置
调试节点是：
/sys/bus/i2c/devices/1-0014/gt9xx_config
直接cat这个节点，可以看到驱动里的配置和实际寄存器的值
更新配置的方法(假设配置文件路径是/data/gt9xx.cfg):
cat /data/gt9xx.cfg > /sys/bus/i2c/devices/1-0014/gt9xx_config
传送配置文件及配置
- window下修改配置文件名为gt9xx.cfg
- window 下打开adb
3.将gt9xx.cfg 传入开发板 /data目录下
3.1 先给权限
adb root
adb remount
adb push gt9xx.cfg /data/
- 进入开发板shell 将传入的配置文件进行配置
adb shell
判断进入开发板后，配置
cat /data/gt9xx.cfg > /sys/bus/i2c/devices/1-0014/gt9xx_config
若想查看是否为所传文件，在开发板shell下分别用cat进行查看
cat /data/gt9xx.cfg
cat /sys/bus/i2c/devices/1-0014/gt9xx_config
