If an external crystal oscillator is used in a DSP, does the input of the crystal oscillator's power supply need to be protected by magnetic beads for EMI, and does it also need parallel capacitors? I...
The WinCE driver itself runs in user mode. Why do we need to call the driver through system calls? Is it okay not to do this? Does the system call cause the program to fall into kernel mode?...
One day, the zoo administrators found that the kangaroos had escaped from the cage, so they held a meeting and agreed that the cage was too low. So they decided to raise the height of the cage from 10...
[color=#222222][backcolor=rgb(238, 238, 238)][font=sans-serif]I'm going to post a few three-wire Jlinks that I made myself. At the time, the project required it, so I made a few samples, but I didn't ...
I use DOS+LOADCEPC to start the kernel. Before entering the system, there will be a NK decompression process, and then jump to a certain address. Problem: There will be a black screen stage during the...
