As the title says. vxworks6.6 has implemented the isolation between kernel and user space. It seems that the service is provided through system calls, which are generally implemented using privileged ...
This is a circuit built with an op amp. Using the virtual short and virtual open methods, we can analyze that the current flowing through RL has nothing to do with the resistance value of RL, but only...
In my design, I first expanded a 6264 (the single-chip microcomputer uses P0 and P2 ports, uses a latch 74LS373, a decoder 74LS138, and the address lines are A13, A14, and A15). However, my design als...
Because I have just learned the analog-to-digital conversion of the 51 single-chip microcomputer, and have not yet learned CPLD and VHDL, I sometimes encounter some problems, so I want to make a frien...
