I am a novice Xiaobai, I am very interested in this project. So I made the pcb 
by myself, according to the content of the website above. But I can't get it 
into the program, which annoys me. I don't know if it's my hardware that's 
wrong. It's still a problem with my software. I hope that the teacher who 
understands can help me check it out, thank you very much here.
