I have been looking for a copy of Professor Liu Runhua’s PPT in the Digital Electronics Video of Petroleum University for several days but couldn’t find it online. If you have any, please send it to [...
I used to use 311 to compare hysteresis directly, but because I copied it, pin 1 was connected to -5V, and the output was not TTL level, so I had to use 9013 to convert it. It worked well. Later, I as...
Why is the first sound wrong when the STM32 uses a timer to control the buzzer? According to the design requirements, it should be a two-short effect, but the first sound is very urgent, but the sound...
During the experiment, I found that if I added a module on the FPGA side, referring to the bmp_save example, the FPGA side wrote the data to the DDR3 on the HPS side through F2H_AXI. Through the Syste...
This solution uses STM8S207C8T6 as the main control, 1.7-inch 128*64 LCD display, LCD driver chip UC1701 (compatible with ST7565), and Qualcomm GT20L16S1Y font chip as the font display, to realize the...
I am currently working on a product for use in cars. All other circuits have been designed, but I am not sure how to handle the EMC of the power supply (the 12V power supply is taken from the car). I ...
With the promotion of the construction of intelligent communities in the country, anti-theft systems have become essential equipment for intelligent communities. Especially in recent years, the urg...[Details]

There are many types of sensors, and the working principles, measurement targets and measurement environments of different types of sensors vary greatly. The corresponding detection s...[Details]
Introduction
Today, as IC (integrated circuit) has developed to a super-large scale, IC design based on IP (Intellectual Property) cores and their reuse are important means to ensure the ef...[Details]
Zarlink Semiconductor has developed an ultra-low-power RF transceiver chip for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices. It has high data rates, low power c...[Details]
The demand for improved healthcare environments is endless, so medical imaging equipment with higher resolution is needed to better observe the human body. High resolution brings problems with sign...[Details]
Battery clamps, commonly known as battery connectors, come in two sizes depending on the thickness of the battery terminals. One is the battery clamp used on thick terminals, with a positive termin...[Details]
Electrostatic coupling and interference occur when a charged object is close to the input of the circuit being measured. At low impedance, the effects of interference are not noticeable because th...[Details]
