best oscilloscope for arduino

I recently encountered some problems when debugging I2C. I hope you can help me with similar problems. Keywords: I2C sub-steady state low speed signal dejitter [Prelude]In the system, the I2C slave function must be implemented in the CPLD to communicate with the I2C interface of the CPU, so as to expand the gpio port of the system. Therefore, according to the requirements of I2C protocol, an I2C slave module and testslave module are compiled with OpenGL, and then simulated and verified in Model

The company bought an oscilloscope a few days ago, and the process was like this: 1. The development department bought an oscilloscope and found a proxy for XX Company in Guangdong on the Internet. 2. So I called:Engineer a said: How much is XX oscilloscope? Sales lady B said: "XXX price" Engineer a said: We are going to buy a batch. Can we get a discount. Sales

Prepare for Power Consumption debugging and prepare for Power Consumption debugging Prepare for Power Consumption debugging December 17, 2014 I. Basic Concepts What is power consumption testing? Power Consumption testing refers to measuring the current of each module in various power consumption states by using various tools (mainly oscilloscope, ammeter, a

A simple test method for super capacitance of capacitance topicIf you need to accurately test the parameters of the supercapacitor, need to set up a test platform, to have a data acquisition system, to have data processing capacity, if nothing, but also need to test, in fact, there are methods, but the means are relatively humble, this is the title of "simple" existence of meaning.So, the headline is a little gallimaufry, and the word is actually:The test method involves three parameters of the

clicks on the application to be tested. For example, the test process of critical module leakage analysis, testing adequacy measurement, code static quality analysis and the collapse of the white box-level capture and analysis. If you have questions about the test results, you can use the client's code coverage visualization to directly validate the results. In addition, all the data from the Nebula test can be traversed in the version, and all data analysis results specifically consider the ag

. It introduces programming languages in the Electronic Art environment, Introduce the concept of electronic art to programmers. It is an extension of the Java language and supports many existing Java language architectures. Syntax is much simpler and has many considerate and user-friendly designs. Processing can be used on Windows and Mac OS x, Mac OS 9, Linux, and other operating systems. Processing features easy to learn and easy to learn. It does not require strong programming experience an

Perhaps this can be thought of as your graduation project or you can use it to control what you want to control, in short you can use it to make a minimal IoT system. However, there may not be such a complex feature here, because the emphasis is minimal. Bareminimum, that's why I didn't change the name of the project on Arduino because it's the smallest, (PS: Everyone knows, if playing hardware). The Internet of things, this thing has been very comple

equipment for basic electrical and electronic technology skills. In order to do better, you can also add some practical lab content related to the professional needs. For example, capacitors are used in automobiles, but there is no requirement in the measurement content in the teaching materials. You can add experimental items for measuring capacitors. There are many sensors on automobiles, some sensors can be directly measured with A multimeter, so the experimental items of the measurement sen

Threadingtest (TT) The first phase is an Android white box test tool, using offline detection method, based on the protection of User source code, the use of plug-in, fifth-generation coverage and other technologies, for development engineers and test engineers to provide a set of efficient quantifiable, visual communication tools. In contrast to other test tools, TT automatically generates the relationship between test cases and code and function coverage in automated tests, and is presented in

Imagination, the cause of a lot of problems, the actual reason only to see to find! If guessing how a failure occurs, it often fixes problems that are not bugs, wasting time and destroying other places, so don't do that. In the medical field, there are stethoscope, blood test, X-ray, B-Super method. Also in software, the method of observation is to set breakpoints, add debug statements, monitor program values, and check memory and so on. Hardware methods such as

At first I was connecting a WiFi module to my Arduino uno, but Uno has only one UART and this UART is connected to the USB port. There have been some and very strange problems. After entering the setup mode (M0=1, m1=1), it is indeed possible to set the parameters of the settings are saved successfully, but using C3C3C3 can not get to the version without any return, may be my RX data line without contact issues.Later I will two UART WiFi module commun
