Hello everyone, I hope all the FPGA experts can help me solve a problem. When using modelsim to simulate the schematic file in quartus ii, you need to convert the schematic file into a .v file first, ...
I recently encountered this problem when doing an experiment. In an ISE project, if I use the xco file of the chipscope core for comprehensive implementation, there will be no problem. If I use the v ...
My stc11f02 can only be programmed once.I have changed 3 chips and it is the same all the time. When I programmed it for the second time, the serial port indicator light did not flash. I don't know wh...
I used one channel to sample 1.5V DC multiple times, and the maximum and minimum values of the AD code I obtained differed by more than 20. This doesn't seem to be a problem of calibration and gain. I...
After VT2 is turned on, the emitter is at a high level, and the collector of VT2 is at a low level. I don't quite understand here. VT2 is turned on, so isn't the collector of VT2 equivalent to a short...
