I have been debugging SPI-FLASH devices recently, so I'll record it. SPI--Serial Peripheral Interface, SPI usually has three signals: SCK clock, STB chip select, and DATA data signal. I2C usually has ...
My environment is S3C2440 + WinCE 5.0 + VNUWCL5 (VIA wireless network card) and driver PB5.0 patch: WinCEPB50-091231-Product-Update-Rollup-Armv4I.msi. An error occurred when obtaining wireless network...
I am currently looking at the driver code for SAMSUN's 2440CAMERA interface, and plan to use OV9650 as the camera. I would also like to ask about the CAM code. I have always been confused about temp =...
Brother Allegro's teaching videos are here~~ All 72 videos, I asked the guy for them, but he seems to use them to make money. The last 51 to 72 videos require a password, and I don't have the password...
At first I wanted to use it to make a thermometer and hygrometer, and then I bought the Xiaomi one.
Later, I wanted to use it in combination with MLX90614 to make an infrared thermometer, and then I h...

Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
China's new energy vehicles are in a transition period from research and development to real industrial development. In 2012, with the intensive launch of new energy vehicle policy planning, the de...[Details]
introduction
Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[Details]
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
At very low temperatures, certain metals and alloys lose their resistance to electric
current
and become
superconductors
. Two parameters that are often measured are the transition ...[Details]
LED lighting: Basic circuit design can be completed in as little as one day
Semiconductor manufacturers are also getting involved in the LED lighting business. The power circuit of LED req...[Details]
The ARINC429 bus is one of the most commonly used communication buses between various subsystems of avionics. As the "skeleton" of modern avionics systems, once the bus system or the attached airbo...[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]
