i2c oscilloscope

I2C bus learning-check for missing traps-S3C2440 I2C Controller After learning the theoretical part of the IIC bus protocol, I think we should learn how to operate the 2440 IIC controller. After all, it is all about learning the S3C2440, so I will add this part. The I2C interface of S3C2440 can work in four modes: Host transmitter, host receiver, slave transmitt

OriginA coworker-owned project scans for the presence of something in the hardware, so the boss would like to have an image-painted interface to view the results of these scans.So a gadget is available to read the data that the colleague has provided and visualize itThat shows the results of the scan is the easiest oscilloscope, but the Third-party control of the oscilloscope function is too cumbersome, and

OriginA project under the responsibility of a colleague scans whether something in the hardware exists. Therefore, the boss wants to view the scan results through an image-based interface.Therefore, we made a small tool to read and visualize the data provided by our colleagues.The easiest way to display the scan results is the oscilloscope, but the functions of the third-party controls are too cumbersome. In the end, I decided to make a simple one mys

For the stm32 oscilloscope, there are a lot of online channels. I want to express my design ideas here. This project has been prepared for a long time. First of all, I would like to thank the previous team. I feel that Chen Shi and Yu have received many considerations from two experienced embedded engineers. If it is not for work adjustment or other reasons, it is very likely that the product will come out. However, I am deeply sorry for not finishing

In the measurement process, the high waveform capture rate is very important for the oscilloscope.Improves the ability of the oscilloscope to capture random events and low probability events. Before describing the waveform capture rate, you must first understand the concept of dead time. What isDead Zone Time? That is, the sum of the next collection and data processing time triggered by the oscilloscope

China site The attenuation device is used to attenuation a large input signal to ensure that the output of the amplifying circuit is not distorted. The main requirement for the attenuation is that the frequency band should be wide enough and the input impedance should be high enough. Since the input impedance of the amplifier circuit connected to the output of the attenuation device is capacitive, the attenuation device usually uses the RC attenuation device. Its principle is as follows: It c

The last simple introduction of the use of Audiorecord and Audiotrack, this time the combination of Surfaceview to achieve an Android version of the phone analog signal oscilloscope. Recently the Internet of Things is very hot, as a mobile phone software developers, how to do not modify the phone hardware circuit under the premise of integration with third-party sensors it? The microphone is a good ADC interface, through the microphone and third-party

1.1GS/S refers to the sampling rate of the oscilloscope, the front s is the meaning of sample sampling, followed by S is the second, that is, the oscilloscope sampling 1G points A second, 1G is 10 of 9 square. That is, a single ad sample can be completed within 1ns.2. Transducers with high input impedance are usually selected, and the probes are divided into active and passive. The application is more passi

Oscilloscope is in the university when the teacher taught, but out of work has not been used, and gradually forget, and now learn again. Look at the effect chart: Here is a custom histogram, and then there is a button, click the button, where the pillars will keep moving, similar to the music player in the oscilloscope beat. Similar to the previous custom view, rewrite the onsizechange () method and th

Weekend play a little Hi, did not update the blog, today to make up, this oscilloscope is in the university when the teacher taught, but out of work has not been used, and gradually forget, and now learn again. Look at the effect chart: Here is a custom histogram, and then there is a button, click the button, where the pillars will keep moving, similar to the music player in the oscilloscope beat. Simil

The last time I briefly introduced the use of AudioRecord and AudioTrack, this time I used SurfaceView to implement an Android mobile phone analog signal oscilloscope (PS: I have also talked about the mobile phone oscilloscope OF THE j2_version before ). Recently, the Internet of Things has become very popular. As mobile phone software developers, how can they combine with third-party sensors without modify

This example of oscilloscope includes a PC and a serial port to send messages, it is worth studying.The general idea is that the sensor node collects data, sends one packet to another base node for each 10 data acquisition, and then the base node forwards the data to the PC side. The PC side has a Java program that collects data and displays it. So run this example to two nodes, a burning oscilloscope, a bu
