The final exam is finally over, and I can start my two-month life of concentrating on 51 learning. I spent an afternoon in the dormitory today, and now I finally got it done. Although it is a very sma...
The gcc project collects voltage values through the ADC0 channel and then displays them on the OLED display. The function is very simple. It is modified based on someone else's ADC0 source code. The s...
I want to use BB board to develop LINUX driver program, but I find that it is all like DOS with black background and white text, which is very annoying. So is there any development environment like C+...

In the analog era, due to the unchanged specifications and relatively simple device connections, as well as users' low requirements for image quality, the relatively simple environment...[Details]
With the continuous emergence of new technologies and the increasing complexity of DSP real-time systems, there are more and more different types of external devices. Writing drivers for these exte...[Details]
1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
Touch sensors have been in widespread use for many years, but recent advances in mixed-signal programmable devices have made capacitive touch sensors a practical, value-added alternative to mechani...[Details]
IntroductionUSB
, serial port, and parallel port are commonly used interfaces for communication between PC and peripherals. However, for images with large data volumes, if the serial RS-232 protoc...[Details]
Preface
In the application of PLL, DLL and CDR circuits, people generally require the output clock signal to have a 50% duty cycle so that data can be sampled at both the rising and fallin...[Details]
When it comes to ATX power supply, people will think of two "classic" ICs: pulse width modulation chip TL494 and voltage comparator LM339. The new dedicated control chip AT2005B has the functions ...[Details]
The full name of RFID is Radio Frequency Identification, which uses radio frequency to realize data transmission between programmable controller (PLC) or microcomputer (PC) and identification, ther...[Details]
