My recent work requires driving DS18B20 to read temperature. After reading the DS18B20 documentation, I felt that it was troublesome. Since only one line was used, the timing requirements were extreme...
The board is very new and has not been used much. Specifically, it is a YC2440 from Taobao, which comes with a 10.2-inch LCD package. The LCD has a driver circuit, 800*480 resolution, and runs the WIN...
I got the board for a long time. My daughter was born last month and I went back to my hometown. I haven't had a chance to test it. Sorry! I tested the WSNdemo test of R21 last night. I just slightly ...
