一、硬件原理图，连接如下:

从上述的原理图我们可以得到管脚的连接：

SENSOR_I2C_SCL1   --->GPIO14

SENSOR_I2C_SDA1  --->GPIO15

EINT-PS ---> GPIO60

2.1 首先跟FAE获取当前项目的驱动代码：

2.2 如下是在cp侧的代码修改如下：

把sns_dd_alsprx_stk3x3x.c、sns_dd_alsprx_stk3x3x.h、sns_dd_alsprx_stk3x3x_uimg.c 放到ADSP.VT.3.0 / adsp_proc/Sensors/dd/qcom/src/ 这个目录

2.3 配置编译如下

2.4 AP侧修改vendor/qcom/proprietary/sensors / dsps/reg_defaults/sensor_def_qcomdev.conf

添加STK3337的配置文件信息
