I am a beginner in STM32F and have played with 51 MCU before. Now I am not very comfortable with using ST's library. I created an MDK project according to the tutorial and added the V3.5 library. Ther...
For example, if I use two hard disks to build a RAID 0, and now I delete the RAID 0 configuration, will the data on the hard disks still be there? For another example, if I use two hard disks to build...
Electronic circuits are often operated with positive regulated output voltages, which are usually provided by buck regulators. If a negative output voltage is also required, the same buck controller c...
I feel that there are still many experts in the world of electronic engineering. I will post another circuit that I published before for discussion.Recently, in my spare time, I have been designing an...
