It is rare to see information about how to send a frame of data in an interrupt manner. If the data frame is sent while waiting, it is a waste of time for a high-speed microcontroller. The following i...
May I ask what testing methods are there for the video intercom system of the intelligent community (including intercom extensions, management machines, door machines, etc.)?...
For example, if we add 8 signed ints, we use three bytes to store the result because the result will not be greater than 0xfff but may be greater than 0xff. Now we have a problem. How do we know wheth...
I work as a PCB layout engineer in a research and development company. I have many years of experience in circuit design and PCB design. I can handle work independently. I have experience in designing...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
Designers use PSpice primarily to simulate analog circuits. However, it can also be used to simulate digital filters. The main components in a digital filter are delay elements, adders, and multipl...[Details]
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
The particularity of portable medical devices determines that they should be user-friendly, must work in a sterile environment, and occupy little space and consume low energy.
At the same time, por...[Details]
This article discusses how to use an ultra-low-power RF transceiver chip from Zarlink Semiconductor for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices t...[Details]
JTAG Technology Introduction
One disadvantage of shrinking technology is that the complexity of testing small devices increases dramatically. When the board area is large, the board is tested...[Details]
Due to the needs of medical development, in many cases, general thermometers can no longer meet the requirements of fast and accurate temperature measurement, such as measuring human body temperature ...[Details]
