Figure 1: Guess the animal from the picture
Even though the animal in the picture is unusually fat, you should be able to guess that it is a giraffe. The human brain has powerful recognition capabilit...
Program structure: main interface thread, two working threads. Both working threads have boards connected to motors. Operating conditions: When the motor is turned on, there is an area on the main scr...
When doing serial communication at 9600 baud, I used an external 32.768K crystal oscillator, and the serial communication was very normal. In order to save cost and module area, I removed the 32.768 a...
