I am writing a key driver now. I have implemented two key drivers, but my problem is that the board does not have many interrupt ports (about 4). I want to write a key driver with about 8, but I must ...
Previously, in the audio driver under WinCE6.0 (in kernel mode), 32B of space was applied for and used directly without mapping or checking embedded pointers. The application writes 32B in, and the dr...
When debugging ARM STM32, do you run it in simulation to find the problem, or do you run it directly in DOWNLOAD and then check the serial port output? Is there any difference?I seem to have seen a bu...
How can I detect the dynamic insertion and removal of the SD card at the AP level? Do I need to write a small driver myself? Or can I only use a timer to continuously query its status?...
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer
