DSP2812's GPIOF4 determines the DSP's startup mode, but I now connected this GPIO port to a pin of another chip. This GPIO port has an internal pull-up inside the DSP2812, but on the other chip, I pul...
I just learned analog electronics. When the book talks about series feedback and parallel feedback, it emphasizes that one is a constant voltage source or a small internal resistance current source, a...

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]
Direct digital frequency synthesis (DDS) has fast frequency switching and modulation capabilities and is widely used. However, when low power consumption and low cost are the main considerations, D...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
Abstract: A motion estimation design for video images is implemented using a powerful FPGA. The search method used is a three-step search method. When designing the scheme, this paper uses the rela...[Details]
The Challenge:
Protect historical relics by monitoring environmental factors without affecting their original appearance.
