[color=#555555]DSP is very fast. To ensure the running speed of DSP, the external memory needs to have a certain speed. Otherwise, the DSP needs to add a waiting cycle when accessing the external memo...
Function: Press a button to start timing, press the button again to pause timing, that is, one button can realize the pause and start function, set another button, press the button for more than three...
I just started to learn 32-bit microcontrollers recently. Haha, I am a little uncomfortable. The firmware library is really good, but it takes time to adapt. A simple USART took me two days to debug. ...
As an emerging microfabrication technology, micro-electromechanical system (MEMS) technology has begun to be applied in various fields. It can integrate functions such as information acquisition, proc...
In the mobile phone keyboard, the hang-up key and the power key are the same key. There is a problem: when the GPIO is set to a high level, it can be used as a hang-up key but not as a power key. When...
For mobile phone FM antenna, is it better to have a built-in one or a pull-out rod? Actually, each has its own advantages. The built-in one is small in size and the pull-out rod has a good signal. But...
This article discusses how to wake up a touch-sensitive device such as a tablet without touching the device, using basic gesture recognition and novel proximity sensors. The article discusses the p...[Details]
