+# mpu60xx
+I2C driver for MPU60xx family IMU. 
+
+## Features  
+  - Read Accelerometer, Gyrometer and Temperature sensor as raw or floating values.
+  - Use in-buit Motion Detection feature using either interrupt or polling.
+
+## Limitations
+  - Does NOT support esp-idf Legacy I2C driver (documentation indicates it'll be removed in future releases).
+  - Not tested with MPU6000. ( TRM indicates it should also work, same register set as MPU6050.)
+  - Supports only I2C protocol ( Only MPU6000 has SPI capability.)
+
+## Important Note
+  - Use deferred processing to handle interrupts from MPU60xx, I2C driver require interrupt to read/write (see example).
+  - INT pin of MPU60xx is required to be connected to esp32 gpio for interrupt. 
+
+## Feature for next release (planned)
+  MPU60xx has many more features which haven't been implemented in this library currently, but are planned to be added in further releases. The next intended feature is
+ - Zero motion detection.
