MPU driver depends on the following protocol libraries to communicate with the chip with ease: [I2Cbus|SPIbus]. You must download the one according to the protocol you'll use and place within your components directory as well. I2Cbus: git clone https://github.com/natanaeljr/esp32-I2Cbus....
MPU-6050是一款由InvenSense公司生产的集成6轴运动追踪设备(MotionTracking device),它结合了3轴陀螺仪和3轴加速度计,可以通过I2C总线进行通信。MPU-6050能够提供包括加速度、角速度、温度等在内的全方位运动追踪数据,非常适合需要运动或姿态检测的应用场合,如手势识别、游戏控制器、可穿戴设备等。 主要特性 六轴感应:...
扩展之后就可以通过其I²C或SPI接口输出一个9轴的信号(SPI接口仅在MPU- 6000可用)。MPU- 60X0也可以通过其I²C接口连接非惯性的数字传感器,比如压力传感器。 MPU- 60X0对陀螺仪和加速度计分别用了三个16位的ADC,将其测量的模拟量转化为可输出的数字量。为了精确跟踪快速和慢速的运动,传感器的测量范围都是...
