app.overlay是board设备树的覆写文件·你可以在app.overlay里边对dts文件内容进行追加修改删除。在文件中添加代码
/** Copyright (c) 2019 Nordic Semiconductor ASA** SPDX-License-Identifier: Apache-2.0*/
i2c1 {mpu605068 {compatible invensense,mpu6050;reg 0x68;status okay;int-gpios gpioa 15 GPIO_ACTIVE_LOW;};
};
二.修改prj.conf
文件中添加代码启用I2C传感器模块和MPU6050模块
# 启用 I2C 和 MPU6050 驱动
CONFIG_I2Cy
CONFIG_SENSORy
CONFIG_MPU6050y
CONFIG_MPU6050_TRIGGER_NONEy
CONFIG_CBPRINTF_FP_SUPPORTy三.修改main.c
mian.c要修改的内容就是MPU6050示例代码里边的内容文件地址/home/user/zephyrproject/zephyr/samples/sensor/mpu6050/src/main.c

}四.编译烧录
在app目录下输入指令
west build -b stm32f429i_alientek -p 成功 west flash
