✔✔✔ Hello, Runxiao L..
Hope you're doing well.
I am ready for this project - "PIC16F886 asm code assistance". Perhaps you will need someone with a strong background in Microcontroller, x86/x64 Assembler, Assembly and Software Architecture.
Because of my unusually strong experience in this area, I could start to contribute right away, perhaps much faster than someone else. You might have a great result which matches your expectations.
Talk to you soon
Olek
