I have more than 10 years of experiences in design, implement, debug and launching products base on the embedded system. I as an firmware engineer had a hands on experiences in many different hardware platform such as AVR, PIC, ARM,8051 etc, also different IDE platform like AVR Studio, IAR, Attolic, Keil, etc.
In this page I'm trying to show you some of these project with my contribution and role.
