Hello everyone, I just got started with ARM, and I encountered a lot of problems at the beginning. I want to light up the two digital tubes on the development board. The board is burned with Win CE 5....
As the title says. vxworks6.6 has implemented the isolation between kernel and user space. It seems that the service is provided through system calls, which are generally implemented using privileged ...
This is a circuit built with an op amp. Using the virtual short and virtual open methods, we can analyze that the current flowing through RL has nothing to do with the resistance value of RL, but only...
In my design, I first expanded a 6264 (the single-chip microcomputer uses P0 and P2 ports, uses a latch 74LS373, a decoder 74LS138, and the address lines are A13, A14, and A15). However, my design als...
Because I have just learned the analog-to-digital conversion of the 51 single-chip microcomputer, and have not yet learned CPLD and VHDL, I sometimes encounter some problems, so I want to make a frien...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]

1. Introduction
This design was made for participating in an electronic design competition. It effectively solved the problem of the operation and control of an electric car on a seesaw. The s...[Details]
With the advent of increasingly powerful processors, image sensors, memory, and other semiconductor devices, as well as the algorithms that enable them, computer vision can be implemented in a wide...[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]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
Vertical cavity surface emitting lasers (VCSELs) are gradually replacing traditional edge emitting lasers, especially in low bandwidth and short-distance communication systems where cost factors ar...[Details]
