What if you don’t have a flight joystick? You can use a PC joystick + Arduino combination. The reason for choosing Arduino NANO is that it is small in size, can meet the I/O requirements, and has a re...
Ahem, actually it should have arrived on Friday, but the courier saw me and didn't deliver to the lab on weekends. The board is relatively simple, leaving the lithium battery power management circuit,...
I found a very strange problem: In the S3C6410+WinCE6.0 system, when two interrupts come at the same time, the number is lost. The details are as follows: There are two tracks for the magnetic card dr...
When WinCE starts, it starts with the startup LOGO, then the startup screen, and then a colorful block flashes before the WinCE desktop appears. Is this caused by some code? I'm very annoyed by this a...
