Today I would like to say thank you to one of senior students who helped me fix the hardware problem of the development board. Actually I felt a little bit depressed and frustrated when I faced that problem. It is because my program had been almost completed but I found that I couldn’t write my program into the board. Besides, the time was so tiny since the demonstration will be held on tomorrow. I had no time to reconstruct the board. Eventually, he helped me to figure out the reason and fixed it. I really appreciated him to give me a hand at that very moment. Thanks God!
