I have been learning drivers for a while. There is one question that I cannot figure out. The driver starts from DriverEntry and then executes various dispatch processes. Is this DriverUnload executed...
GC4931F/S is a three-phase brushless DC motor pre-driver chip. The chip can drive N-type power MOSFET with a maximum power supply of 36V. The chip state switching logic is determined by three Hall inp...
[backcolor=rgb(239, 245, 249)]I used to develop 51 MCU and ARM MCU. AVR is just between them. I just didn't use it before. Now the company has an old product made of mega32 chip, which needs me to mai...
After connecting to the serial port debugging, the next thing that comes is Flash emulation EEprom to store data.
Why not just use an EEprom chip like AT24C02?
There are two main reasons:
1. Cost issu...
Today, I was browsing the Internet and saw that ADI also produces MP4 chips. I think they are good. In my impression, they are basically AD converters: The following is from the Internet: After the vi...
