StickC IMU
The IMU automatically selects the model based on the host configuration
Init()
Function:
Initializes the IMU chip
Syntax:
int Init(void)
Example:
cpp
1 2 3 4 5 6 7 8 9
#include <M5StickC.h> void setup() { M5.begin(); int x = M5.IMU.Init(); //return 0 is ok, return -1 is unknown. If the return value is 0, initialization is successful Serial.println(x);}void loop() {}getGyroData()
Function:
Gets the three-axis gyroscope data from the IMU chip
Syntax:
void getGyroData(float *gx, float *gy, float *gz)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
#include <M5StickC.h> float gyroX, gyroY, gyroZ; void setup() { M5.begin(); M5.IMU.Init();} void loop() { M5.IMU.getGyroData(&gyroX, &gyroY, &gyroZ); M5.Lcd.setCursor(0, 30); M5.Lcd.printf("X:%7.2f/nY:%7.2f/nZ:%7.2f ", gyroX, gyroY, gyroZ); delay(500);}getAccelData()
Function:
Gets the three-axis accelerometer data from the IMU chip
Syntax:
void getAccelData(float *ax, float *ay, float *az)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14
#include <M5StickC.h> float accX, accY, accZ; void setup() { M5.begin(); M5.IMU.Init();}void loop() { M5.IMU.getAccelData(&accX, &accY, &accZ); M5.Lcd.setCursor(0, 45); M5.Lcd.printf("X:%5.2f/nY:%5.2f/nZ:%5.2f ", accX, accY, accZ); delay(500);}getAhrsData()
Function:
Gets the attitude data from the IMU chip
Syntax:
void getAccelData(float *pitch, float *roll, float *yaw)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14
#include <M5StickC.h> float pitch, roll, yaw; void setup() { M5.begin(); M5.IMU.Init();}void loop() { M5.IMU.getAhrsData(&pitch, &roll, &yaw); M5.Lcd.setCursor(0, 45); M5.Lcd.printf("X:%5.2f/nY:%5.2f/nZ:%5.2f ", pitch, roll, yaw); delay(500);}getTempData()
Function:
Gets the temperature data from the IMU chip
Syntax:
void getTempData(float *t)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14
#include <M5StickC.h> float temp; void setup() { M5.begin(); M5.IMU.Init();}void loop() { M5.IMU.getTempData(&temp); M5.Lcd.setCursor(0, 45); M5.Lcd.printf("Temperature : %.2f C", temp); delay(500);}
