After the 24-bit 7-inch LCD screen and touch screen are debugged, the writing of Qt programs will be put on the agenda! Because I use the official SDK, it comes with the Qt4.8 library! All I need to d...
I wrote two read and write functions according to the timing in the manual, but the read and write data are always wrong.
I found a lot of relevant information on the Internet, and it seems that their...
If the differential circuit is single-ended (and 3-point output), why is there no noise? It is easy to understand that the signal is output from points 3 and 2, because the collectors on both sides ar...
