User programs need to access physical addresses to control peripheral FPGA chips. I have no experience with this, and all I can think of is to write a dll, use MmMapIoSpace() to make a mapping, and un...
This is a circuit of LM358. I disassembled the amplifier inside the chip and drew a diagram. I checked a lot of information but couldn't figure out what function this diagram is supposed to achieve. T...
