After reading Shao Beibei's book > and looking at the overall framework of these books, I have two questions in my mind: 1. The book talks about the porting of μC/OS-II to 80X86, but after porting μC/...
Virtual memory uses disk to expand memory capacity. It is also called "memory-external memory hierarchy". Where is the external memory in Windows Mobile?...
Let's discuss how many DA bits should be selected for this CNC constant current source.(1) Output current range: 200mA~2000mA; (2) The output current given value can be set and displayed, and the abso...
1. The grounding device should be made of steel, and the conductor cross-section of the grounding device should meet the requirements of thermal stability and mechanical strength. 2. The buried depth...
When developing microcontrollers, there are often some insignificant problems. These problems are actually very basic C language knowledge points and some small details. But precisely because they are...
The simulator just can't connect and doesn't report any errors. After the simulator pops up, it keeps saying "server is started". The program can't be downloaded, and then it says "download failure" n...
