I have the impression that the principle used by Zener diodes and TVS tubes is that the voltage does not change much in a large current change range. Therefore, a general Zener diode is connected in s...
I have some ferrite beads, MMZ2012 series, 60 ohm, 1000mA maximum current, I want to use it for power supply, but the data sheet of this ferrite bead says that this series is for signal line, can I us...
Recently, I ran an interrupt program on the s3c44b0x board, and it always failed. After considering all the situations, I think the ISR_STARTADDRESS value is a possible error. The source program defin...
