ARM based 32bit precision angular degree movement sensing for any rotary shaft mechanism

The research purpose is to give a simple design ideas for accurately detecting the angular position of a rotating mechanical shaft that are commonly used in industrial machines that can be seen on manufacturing plants such as semiconductor, food, textile products and etc. This proposed angular position measurement system is designed to monitor any changes of angular movement due to wear and tear of mechanical fittings, wrong settings, dirt and debris, operating temperature of the process and many factors that may affect the detection and normal operation of angle for the rotational shaft. The system consists of four main parts: an ARM Cortex M4F Microcontroller, Rotary Code Wheel, Optical Rotary Encoder, Quadrature Decoder with 32bit Counter Interface. Aside from the accuracy and precision, this system also promises a very big cost savings in terms of lifespan and adapt to other existing system.
