I would like to ask you experts: How to map physical addresses in user-mode drivers in WinCE6.0? For the following code, if this driver is run in user mode, the output vpReg is 0. If anyone knows how ...
It is a simple keypad, and the control and power circuits are on other PCB boards. I am currently routing all the wires (including the ground wire) on the top layer. I would like to ask if both the to...
Why do some designs connect dozens of capacitors in parallel to a network (power supply) with the same name instead of using a few capacitors with relatively large capacitance? I hope experts can give...
