1. OverviewThe GD32F4 series is the earliest M4F core MCU I know of in China. Several other series such as F3 and E1 are M4 cores without hardware FPU, which are obviously inferior in some computing s...
One afternoon, my classmate was working in Construction Bank and was bored. A woman (a psychopath) dressed badly came to his window and gave him a note to withdraw money. The note clearly said "Comrad...
If you need to count high-speed (about 100KHz) random pulse signals with uncertain frequency and pulse width, what kind of circuit should you introduce the signal into? What kind of counting method sh...
As shown in the picture, I use a 20KHZ square wave to drive the IGBT. Why does the IGBT heat up so badly? Logically, this IGBT is 1200V/25A, and my voltage is only 20V/800mA. What's the problem? Is it...
