My laptop doesn't have a serial port, so I bought a USB to serial port converter and used minicom -s to set: "ttys1" is serial port 1, "ttys2" is serial port 2. The question is: which serial port is t...
I am using ORCAD version 15.7. I want to use transient analysis to analyze the voltage waveform at the OUT terminal. The excitation signal is VPWL, but the simulation always prompts me that there is a...
I originally understood that the CPU clock frequency is the number of instructions executed per second, but later I found that MIPS is the reference value of the CPU clock frequency. By the way, does ...
As the title says, my small program does not use non-modal, but two-modal dialog boxes. After the program starts, a dialog box is called with dialogbox, and another dialog box is called with dialogbox...
