Abstract: The successive approximation register type (SAR) ADC occupies most of the medium to high resolution ADC market. The sar adc has a maximum sampling rate of 5 MSPs and a resolution of 8 to 18 bits. The SAR architecture allows high-performance, low-power ADC to use small-size packages and is suitable for systems
1. In order to implement the binary search algorithm, the N-bit register is first set to the intermediate scale (that is, 100... 00, and MSB is set to 1 ). In this way, the DAC output (vdac) is set to vref/2, and vref is the reference voltage provided to the ADC. Then, compare and determine whether vin is smaller than or greater than vdac. If Vin is greater than vdac, the MSB of the comparator output logic is 1 or 1, and the N-bit register is 1. Conve
Overview
Equalizer is an OpenGL-based parallel rendering system framework. Its developers are from the University of Zurich in Switzerland. The latest version is 0.3. It is estimated that version 0.4 will be released soon.In short, equalizer wants to construct an OpenGL-Based Graphics Rendering framework. Unlike the rendering engine, equalizer provides control o
Today, when I updated the svn library of equalizer, I saw the release notes about version 0.4 under the doc directory. As a preview version of Beta, it is getting closer and closer.
As an extensible OpenGL application framework for development and deployment, applications developed based on Equalizer
ProgramIt can run on various platforms without any modification, from single GPU to SLI systems, from sing
First we find the Equalizer, click "Set" = "view" = "Equalizer".
We'll have to adjust the parameters when we find the equalizer. Open the equalizer after a variety of different effects, including rock, dance, fresh, blues and so on, you can listen to different songs to set up, you can also be on the right side
Equalizer is an excellent OpenGL middleware. It is an open-source software and can be used commercially.
The best way for beginners to get started or understand is to run a simple program and check its effect. However, it is not easy to understand the concept. Here, I will explain that you can run two small examples step by step.
First, install the installation package in Windows

Preview of ogre integrated with Equalizer
Some days ago, I tried to integrate ogre with equalizer, put some pictures first, and sort them out in a few days.CodeThe last part is made public.

Yesterday, I received an email notifying you That the eqogre created some time ago, that is, an application example of extending ogre through equalizer, has been integrated into the equalizer development project and can be obtained through SVN.As eile said, although his efforts have been made to modify eqogre, eqogre is still not perfect, so it is not added to the development project of the project, but in
Stm32--adcTenet: The learning of technology is limited and the spirit of sharing is limitless.First, ADC IndicatorsThere are 18 channels to measure 16 external and 2 internal signal sources. The A/D conversion of each channel can be performed in a single, continuous, scan or discontinuous mode; the results of the ADC can be left-aligned or right-aligned in a 16-bit data register, and the analog watchdog fea
This problem I am my own idea, once a, 0.000ms. Look at the online most of the solution is similar, I would like to talk about my ideas.Assume that the string a, bAll we have to do is sweep it backwards. Jump over, encounter a[i] = ' 0 ' a[i]!=b[i]; then look back for a a[j]== ' 1 ' a[i]!=b[j], that is to say, the first exchange of this skill to compare the provincial steps. If there's nothing to swap, then sweep again? What if a[i]==? B[i]==0 So obviously we can start with? becomes 1 again and
I just published the sample code for extending the Ogre application with Equalizer on Blogspot. Because equalizer was developed by foreigners, it was written in English and a little lame, change it to Chinese when you are free.For more information about the examples, see my previous articles.
Eqogre is my test project for integrating ogre application with equalizer

High speed ADC Clock jitter solution
The clock jitter of the high-speed ADC affects the SNR of the high-speed ADC, while the signal-to-noise ratio determines the effective range of the analog front-end input. Therefore, it is necessary to determine the effective input range of the analog front end, then determine the SNR that should be satisfied, and then deduce

1. Turn on the cool dog and play the music so that we listen to the different sounds. Click on the "main Menu" of "Equalizer" to open equalizer mediation.
2. Click on the preset button, you can see that there are preset sound effects, such as "classical", "Dance", "Scene", "Hall", "Rock" and so on.
3. Then click on any of the preset sound effects to turn on this sound. For example,
In application note, ADC already has many examples, but it lacks a multi-channel scheduled scanning routine. Theoretically, the ADC is configured as a multi-channel ADC conversion, which is used with DMA for data transmission and is automatically triggered using timer + PRs. This function should be completely OK. However, there is only a lack of routines and self
The function of the balancer is to adjust the signal strength at different frequencies.
As a wave, sound has three elements: amplitude, frequency, and phase. The amplitude determines the sound size, and the frequency determines the sound tone. The actual sound is often not a single frequency wave, but a superposition of various frequencies, thus forming a distinctive sound.
