Hello @Vignesh_V,

Sorry, but from someone external to your project, the description of your issue is tough to understand.

From what I understand, you want to measure the speed of a ship engine, but the control of the engine itself is not done by your STM32F407 right? If I guess properly, your question is absolutely not related to Electric BLDC motor control. What kind of motor is your ship motor?
