If my WINCE device enters Mass Storage Mode, then if the device is connected to a PC at this time, WINCE cannot recognize the contents of the Flash and SD card, and the PC (WINXP) sees the device as a...
I debugged several boards, and the other boards were all good. But one of them crashed when I left the simulator? And it didn't run when I powered it on again. Does anyone know why?...
As the title says: When the lower computer is working, it will generate a large amount of sampling data (nearly 5,000 times per second, and it may be faster if effective communication is possible). It...
