I am currently working on a digital set-top box project, the solution was provided by another company. During the process of making the prototype, I encountered a problem, that is, the buttons on the ...
I've been working on the mixer in AUDIO recently. My audio driver model is wavedev2. But I put mixerdrv into it and nothing happened. The 8K sampled file was not converted to 44.1K when it was passed ...
In biological measurements, such as ECG, EEG, EMG and other signals, these signals not only have extremely small voltage levels (ECG - milliampere level, EEG - microampere level...), but also have ver...
I ran out of toothpicks! The toothpick holder is transparent, so I made a USB light with random things! I don't have to turn on the desk lamp to find the computer keyboard at night! Haha!...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
System design is a complex process. It is not enough to just use ICs. There are many details to consider. This article uses a high-fidelity music playback system as an example to introduce how to s...[Details]
