The oversampling architecture places the quest frequency away from the signal bandwidth, while the digital decimation filter attenuates most harmful out-of-band signals. When combined, they enable more free antialiasing filter responses, wh

The touch screen is summed up as input subsystem, here is mainly for the resistive screen, the use of the process is as follows: When the touch pen is pressed, resulting in an interrupt. Start the ADC conversion x, y coordinates in the interrupt handler function handler. The ADC is terminated, an ADC interrupt is generated, a timer is escalated in the

If the Jetson TK1 audio is not available, you can enter the following command at the terminal and test again, you can use it. (Note: On the Jetson TK1 hardware, on the audio, above is the microphone, below is the handset).Amixer cset name= "Stereo ADC MIXL ADC2 Switch" 0amixer cset name= "Stereo ADC mixr ADC2 Switch" 0amixer cset name= "Int Mic Switch "0amixer cset name="

Introduction to internal integrated ADC of stm32I. The reference voltage range is/* 2.4V ≦ VListen 3.6 VTherefore, its input analog voltage range is 0 2. When a negative voltage is measured or the measured voltage signal is out of the range, it must first be translated through the calculation circuit or by using the resistance partial pressure.3. I use the 10 k resistance of 51 Single-Chip Microcomputer to simulate input.Iv. Rule channel and injection

I. ADC (DMA mode) 1. clock frequency settings The maximum clock frequency of the CPU is 72 MHz, while that of the ADC module is 14 MHz. To achieve the maximum clock frequency of the ADC module, the maximum CPU frequency can only be set to 14 m x 4 = 56 m. (The commonly used clock frequency of pclk2 is 72 MHz, and the adcclk must be lower than 14 MHz. Therefore,

s3c2410/s3c2440 ADC and touch-screen interfaces have the characteristics of waiting for interrupt mode. So you need to write an interrupt function to complete the reading of ADC data.The following code is tested through the friendly Ucos transplant version ~Interested friends, you can download the bin file to actually test, based on the Ecgui graphics system simple demo, support touch screen correction.Link

After 1 days, the ADC has not come out and found that the value of the processing is always fixed value. Go to 21IC for help stickers.

Learning Goals: I/O port configuration, master I/O peripheral function and position distribution , register "percfg", "P2sel" and "p2dir".Front CC2541 bluetooth learning--I/O introduced CC2541 has 21 I/O pins that can be used as general-purpose I/O pins, and can also be used as peripheral I/O pins for ADC, serial, timer and Debug Interfaces . When set to peripheral I/O, it is necessary to place the corresponding register bit Pxsel 1, each peripheral u

help you a little.Recording process and hardwareFirst of all, why emphasize the recording function of mobile phone.It's simple, the phone is used for calling. The process of the call, the first to record the voice of the speaker, and then the listener can hear. Therefore, the recording function for the call, is fundamental and important.For the mobile phone recording process, simply speaking, need to go through three stages, two links. Three links are: "Sound-analog electrical signals-digital e

, then if there is a server connection number of 0, the equalizer directly forwarded the request to it, without the SED calculation.9, LBLC based on the least local connection. Based on the destination IP address of the request, the equalizer finds the server that the IP address was recently used, and forwards the request, if the server is overloaded, the least number of connection algorithms are used.10, L

them:First, the advantages of LVS:1, strong anti-load ability, because the LVS work mode logic is very simple, and work in the Network 4 layer only to do the request for distribution, no traffic, so in the efficiency of the basic need not too much consideration. In my hand, the LVS, just once the problem: in the concurrency of the highest period of time the equalizer packet loss, according to the analysis of network problems, that is, Nic or linux2.4

Comparison of load balance between LVS, Haproxy and NginxFrom the performance and stability of the most bull LVs, basically reached the F5 hardware equipment 60% performance, a few other 10% are a bit difficult. But because of the LVS bull, configuration is the most troublesome, and health testing needs to be configured Ldirector, other haproxy and nginx themselves, and the configuration super simple.If the site visits are not portal level with haproxy or nginx OK, to the portal level in the use
