I soldered two circuit boards at the same time (mainly including single-chip microcomputer, video character overlay, 485 control), one works well, and the other does not. The poor performance is that ...
Hello everyone! I have a PWM problem with the TMS570LC4357. I would like to ask how to set the phase difference between the three-phase PWM of [color=rgb(170, 102, 102)][url=http://www.ti.com.cn/produ...
I'd like to ask you guys, I chose the cyclone series EP2C5 for my entry level, which has only 144 pins. Excluding the core board, there are only 87 I/Os left. If I want to implement Niosll, do I need ...
I wrote a program to sample AC voltage using AD. I found that the first sampled data after each program run is wrong. For example: The samples matrix is used to store the sampled result values. Sample...
