SH200Q

The SH200Q is a 6-axis IMU chip, including a gyroscope that measures angular velocity values in the X, Y, Z directions, and an accelerometer that measures acceleration in the X, Y, Z directions.

Init()

Function:

Initializes the SH200Q chip.

Function Prototype:

void Init()

Usage Example:

#include <M5StickC.h>

void setup() {
  uint8_t c;
  M5.begin();
  M5.IMU.Init();
  M5.IMU.I2C_Read_NBytes(SH200I_ADDRESS, SH200I_WHOAMI, 1, &c);
  M5.Lcd.print("SH200Q I AM "); M5.Lcd.println(c, HEX);
}
void loop() {}

getGyroData()

Function:

Gets the three-axis gyroscope data of the SH200Q chip.

Function Prototype:

void getGyroData(int16_t* gx, int16_t* gy, int16_t* gz)

Usage Example:

#include <M5StickC.h>

int16_t 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 mg",
                ((float)gyroX) * M5.IMU.gRes,
                ((float)gyroY) * M5.IMU.gRes,
                ((float)gyroZ) * M5.IMU.gRes);
  delay(500);
}

getAccelData()

Function:

Gets the three-axis accelerometer data of the SH200Q chip.

Function Prototype:

void getAccelData(int16_t* ax, int16_t* ay, int16_t* az)

Usage Example:

#include <M5StickC.h>

int16_t 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 o/s",
                ((float)accX) * M5.IMU.aRes,
                ((float)accY) * M5.IMU.aRes,
                ((float)accZ) * M5.IMU.aRes);
  delay(500);
}
