Can SH200Q detect tilt to gravity? #23

Closed naninunenoy closed 5 years ago

naninunenoy commented 5 years ago

I would like to calculate posture of M5StickC. But it seems that accelerometer in SH200Q does not reflect gravity acceleration. SH200Q only provides linear acceleration?

SH200Q is an inertial measurement unit,integrated with 3-axis gyroscope and 3-axis accelerometer.It provides high precision data of real-time angular velocity and linear acceleration,

Sorry, I used old version library 0.0.5. SH200Q values are modified in 0.0.7, but IMU.cpp and example code of SH200I still look strange.
