使用icm-42670-p 计算倾斜角度,并生成代码
ICM-42670-P是一款高性能、低功耗的6轴运动传感器,可用于计算倾斜角度。以下是一个示例代码,使用ICM-42670-P计算倾斜角度:
```c
#include <Wire.h>
#include <ICM_42670_P.h>
ICM_42670_P imu;
void setup() {
Serial.begin(9600);
Wire.begin();
if (!imu.begin()) {
Serial.println("Failed to initialize ICM-42670-P");
while (1);
}
imu.setGyroRange(ICM_42670_P_GYRO_RANGE_2000DPS);
imu.setAccelRange(ICM_42670_P_ACCEL_RANGE_16G);
}
void loop() {
imu.readSensor();
float ax = imu.getAccelX_mss();
float ay = imu.getAccelY_mss();
float az = imu.getAccelZ_mss();
float pitch = atan2(-ax, sqrt(ay * ay + az * az)) * RAD_TO_DEG;
float roll = atan2(ay, sqrt(ax * ax + az * az)) * RAD_TO_DEG;
Serial.print("Pitch: ");
Serial.print(pitch);
Serial.print(", Roll: ");
Serial.println(roll);
delay(100);
}
```
在这个示例代码中,我们使用了ICM_42670_P库来读取传感器数据,并计算出了pitch和roll的角度值,然后通过串口打印输出。注意,我们使用了三角函数函数`atan2()`来计算角度值。该函数的参数为两个数值,第一个参数为y轴值,第二个参数为x轴值,返回值为该坐标点的弧度角度。最后将弧度转换成角度值,通过串口输出。
ICM-42688-P例程

这是一个简单的例程,仅仅测试了 ICM-42688-P 是否被正确识别。您可以根据自己的需求,使用 ICM42688_SPI_Read 和 ICM42688_SPI_Write 函数来读写 ICM-42688-P 的寄存器。同时,您也可以将这段代码移植到您自己的工程中,根据需要进行修改和调整。
