Not long ago, I tried to compile binary files with GNU tools so that I could run the written C or assembly "naked " code directly on the ARM development board without running the operating system. I d...
The electric motor is also called a pulse motor or a step motor. It is generally called a stepping motor , pulse motor or stepper servo abroad . It is a discrete motion device. The stepper motor drive...
Although the DAC function of the microprocessor can output a relatively accurate voltage, not all microprocessors have it, and it is difficult to light up the LED. ize=13px], there are some defects in...
I have a car GPS, the operating system is wince5, but a lot of tool software I found on the Internet can't be used on it (50% unavailable, prompt illegal operation), but it can run on wince5. The same...

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[Details]
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]
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]
The Mobile Industry Processor Interface (MIPI) Alliance is an organization responsible for promoting the standardization of software and hardware in mobile devices. It has released the D-PHY specif...[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]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
Instrument stepper motor
The stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
With the rapid development of intelligent control technology, computers and information technology, the trend of information appliances IA (Information Application), computers and communications integ...[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]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[Details]
