MSP430F5438A MCU low power setting, take entering LPM3 as an example: 1. The external clocks of MSP430F5438A are 8M and 32.768 respectively. When the program runs normally, the 8M main clock is select...
Abstract: A new type of voltage probe soft switching inverter topology is proposed. It can achieve the zero voltage switching (ZVS) condition of each power tube in the inverter bridge very simply with...

BYD car navigation uses winc5.0 system ARM9 + 64MB memory all-in-one machine. We found that only the original navigation software can make sound. If the navigation software is changed, there will be n...
T1 and T2 are PNP transistors, and the collector is grounded. So when the input IN+ and IN- are both greater than zero, the collector junctions of T1 and T2 are reverse biased, and they either work in...
