ESP32+MPU6050 Interfacing without Adafruit Library

Today we are going to write a baremetal kind of code for accessing the values from MPU6050 in ESP32 Wroom Nodemcu module without using Adafruit library. Sometimes we just need a plain reading and using an external library seems overkill, besides, it hides lot of underlaying simplicity and do hardware abstraction that it will not let us see how simply things could be done. Our today’s approach…
