The Ethernet KITL is connected, but it stops after loading some stuff. I am using the Youlong 2440a development board. The PB shows: 294772034 PID:c3d93bfa TID:c3d934aa 0x83d93000: [dm9: Chip signatur...
UWB (Ultra-Wideband) is a high-speed short-range wireless technology. It was first introduced in the IEEE 802.15.3a standard. The latest version defining the UWB specification is specified in IEEE 802...
51 is very popular and powerful, but it is not suitable for the development of future hardware systems. Although many manufacturers provide single-cycle chips with extended interfaces, the speed of 51...
I am currently working on my graduation project. I designed a simple SPI port on an Altera development board. The communication is normal, and I can use four wires to perform 10-bit binary serial tran...

Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]
introduction In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[Details]
From last year to now, competition in the photovoltaic inverter industry has become increasingly fierce. In addition to the introduction of new products, various marketing and promotion methods hav...[Details]
Timing and protocol are two key points in digital system debugging, and they are also where logic analyzers can play their most valuable role. How can we use a logic analyzer to quickly complete wiri...[Details]
This paper combines embedded control technology with network control technology to realize the design of temperature control system based on single chip microcomputer through Internet control. Th...[Details]
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
Internal channels of ADC: In addition to using external channels to collect external analog voltage signals, the ADC of STM32 also has two internal channels 16 and 17. Channel 16 is connected to ...[Details]
