Although there are many retro game consoles developed based on Raspberry Pi, they are also easy to buy.
But it is still necessary to recommend the following one - a retro game cons...
Transistor static operating point--------If the static operating point is not set properly, saturation distortion (static operating point is too high) or cutoff distortion (static operating point is t...
[size=4][color=#000000][backcolor=white] DSP (Digital Signal Processing) is digital signal processing technology, and DSP chip refers to the chip that can realize digital signal processing technology....
In embedded development, we often need to call some mathematical functions, such as pow, acos, asin, sqrt, etc. At this time, we need to add a reference to the standard math library.
Taking RISC-V IDE...
[size=4] In general, the 430 microcontroller has three timers, timer A, timer B, and watchdog timer. Here we mainly discuss the function of timer A of the 430 microcontroller. The function of timer A ...
Solar cells or photovoltaic PV cells are devices that absorb photons from a light source and then release electrons, which can cause current to flow when the solar cell is connected to a load. Solar ...[Details]
The countdown program with preset start time is used to time an event in daily life: as long as the time set by the human is reached, the countdown circuit will sound an alarm. The characteristic o...[Details]

According to foreign media reports, Panasonic said on November 15 that it will purchase recycled battery cathode materials from Redwood Materials starting in 2025 for use in its new factory in Kansas...[Details]
Introduction
The IO voltage of a general-purpose MCU or DSP is usually 5V3.3V, and the current output capacity of the IO is below 20MA, which is not enough to directly drive the power MOSFET....[Details]
With the widespread promotion of smart grids, how to balance electricity demand has become the key, and home energy management (HEM), as the last link in the chain, has also begun to move from conc...[Details]
Let's analyze the output current value of the PLC's own 24V power supply. The output current value of each brand of PLC's own 24V DC power supply is different. We can find out from the PLC manual t...[Details]
Usually, audio circuits include capacitors for filtering, coupling, bypassing, and frequency division. How to more effectively select and use
different types of capacitors in the circuit has a ...[Details]
