The design task requirements of the signal generator are: 1) Frequency range: 100Hz~1MHz; 2) Can generate triangle wave, square wave and sine wave; 3) Stable output voltage, Vopp=6V; Performance part:...
This is Moen's suggestion: LM3S8962 has 256KB FLASH, 64KB SRAM, CAN, 10/100 ETH, 10bit ADC, PWM. The price of a single chip seems a bit high, but compared with similar products such as: STM32 series M...
Obviously, now that I have decided not to worry about this or that, and I have discovered that Contiki contains much more than I imagined. So an idea has become stronger and stronger in my heart: Forg...
I use SPI between my STM32 and CPLD, and each SPI port line is connected in series with a 0 ohm resistor. Now SPI communication is not working. Is it because of the series resistor?...
The low voltage microprocessor supervisory circuit can form a low voltage, low power LED flasher, and can adjust the lighting time and flashing rate. The μP supervisory circuit (IC1) is powered by two...
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]
According to the Industrial Technology Research Institute of Taiwan, due to factors such as the oil crisis and global warming, the issues of energy conservation and environmental protection have at...[Details]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
A few days ago, I bought an 8LED flashlight in the market (the flashlight uses No. 5 batteries). Because I had other things to do, I didn't pay attention when purchasing it. When I got home and use...[Details]
The power supply is the core component of a computer. Although it is not of high value, all computer components rely on the switching power adapter to provide energy, so the stability of a power su...[Details]
There are many types and styles of digital voltmeters in design and development. Traditional digital voltmeters have their own characteristics. They are suitable for manual measurement on site. Tra...[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]
