Hello dear,
I'm Mohamed Adel, a professional embedded software engineer. I've worked on many projects that involved many different microcontrollers and wide range of applications. I see that you aim to achieve your project using the Nuvoton MS51FB9AE device, I've already worked for multiple times on more complicated and professional targets regarding ARM microprocessor such as stm32f1/f4 and tivaC microcontrollers. Also you mentioned the UART which I've implemented the software drivers for many targets to achieve perfect communication between the sender/receiver. I've worked on keil platform many times for stm32 microcontrollers and used its simulator to validate the work. Kindly check my profile to see my previous work and experience.
I will work on this project as a priority to make sure that I complete all the requirements as soon as possible, and to enable you to revise the work well and make any modifications if required.
I'm starting my freelancing career, and I'm really interested in providing a completed and professional work, and achieving your satisfaction. Looking forward to hearing from you soon to further discuss your project needs.
Best Regards,
Mohamed Adel
