I hope you are good. I have read your description carefully and understand everything. I’m Electronics engineer who have 25 year experience on analog design, renewable energy, power electronics, motor control, microcontroller coding and PCB design. I have used Arduino, PIC, MSP430, C2000 and STM32 for 8 years. I have developed several codes by using their IDE and compilers. I know all principles of them. And I can do microcontroller simulation by using Proteus. Proteus have microcontroller model and peripheral components to simulate the code. The code can be debugged by using COF file also. Simulation result is same with real time application.
