StickC SH200Q IMU
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.
Syntax:
void Init()
Example:
cpp
1 2 3 4 5 6 7 8 9 10
#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.
Syntax:
void getGyroData(int16_t* gx, int16_t* gy, int16_t* gz)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
#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.
Syntax:
void getAccelData(int16_t* ax, int16_t* ay, int16_t* az)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
#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);}
