I did the following five steps: 1. Add Catalog->Core OS->Windows CE devices->Core OS Services->USB Host Support->USB Storage Class Driver 2. Add Catalog->Core OS->Windows CE devices->Core OS Services-...
F28335 board, 510 emulator. Two assembly programs were compiled. Program A runs in RAM, and two LEDs flash at the same time. Program B has been written to Flash, and two LEDs flash alternately. Debugg...
When I call com in asp, memory leak occurs. The test method is to open the page containing com, then do nothing. When I operate again after 10 minutes, I find that the memory will increase by about 50...
I would like to ask all the experts, I have already learned the design software of VHDL and CPLD/FPGA, but I still can't figure out how it realizes the control target and how it is realized? For examp...
A multi-point temperature control heating control system was designed using the SST89E564RC single-chip microcomputer and a new temperature measuring device. The heating system can be controlled in...[Details]

1 Causes of problems with electric vehicle batteries
1.1 Caused by the battery itself
Why do we say that? In the previous issue, we learned about the working princi...[Details]
Lithium iron phosphate batteries are used as lithium-ion secondary batteries. Their main application is now in power batteries, which have great advantages over NI-H and Ni-Cd batteries.
Lithi...[Details]
With the continuous development of integrated circuit technology, integrated circuits have developed from thousands of gates to the current level of millions and tens of millions of gates. The applica...[Details]
Any power transmission and distribution equipment and power-consuming devices cannot be pure resistive loads, so they must occupy a certain amount of reactive power. The existence of reactive curre...[Details]
1 Introduction
The early stage control system used relay control. Due to the large number of stage equipment, the number of control elements is huge and the wiring is complicated. Therefore, th...[Details]
Today's advanced electronic systems for the telecom and datacom markets rely heavily on high-performance, fine-line digital ICs (FPGAs, DSPs, and/or ASICs) to quickly and efficiently process time-s...[Details]
