I'm looking for an answer to a question that's very confusing to me. How does an MCU control and monitor the devices connected to it when the embedded OS runs on it. For Example, Embedded system have buttons, motor and LCD connected to a micro controller. How embedded OS control and monitor buttons, motor and LCD.
I found that the OS does not communicate directly with the buttons, motor and LCD. Application program communicates with OS program.
I have come to the conclusion that the OS program is a universal program. If an external device is to communicate with the microcontroller, it must write an application program for the device. This application program works with OS program.
How does an MCU control and monitor the devices connected to it when the embedded OS runs on it.
I have expressed my views now I want someone to give their opinion on this
