I need some advice. My program needs a parameter from the host computer to start executing. The problem is that the current increases a lot immediately after the program is downloaded, and then it inc...
First of all, I would like to thank eeworld and Shijian eSHOP for organizing this event. I was surprised to receive this award. Usually, I forget about the events after I attend them. I don't know wha...
With the deepening of economic system reform and driven by the market, digital energy meters have developed rapidly. China has now become the most dynamic market in the world's energy metering industr...
The communication part of the fieldbus is generally divided into dispatch communication and non-dispatch communication. Most of them are dispatch communication, which is used for periodic transmission...
As shown in the figure, we often see the description of IR series ICs that "the du/dt interference resistance is 50 V/ns". What does this mean? Also, we see elsewhere that "a smaller gate resistance a...
Protel 99SE can be used after it is installed, but it prompts that the license has expired. It cannot be used after a while. The signs of schematic diagram, library, etc. do not appear in the new crea...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
