How to use ADC with STM32?
Using ADC with STM32, ADC channel selection, ADC setting, ADC regular conversion mode, Injected simultaneous mode, Regular simultaneous mode
An Analog to Digital Converter (ADC) converts a continuous signal (usually a voltage) into a series of discrete values ??(sequences of bits). The main features are: Resolution (in analog terms): It is the minimum variation of the analog input voltage that can determine the variation of the LSB, that is of the least significant bit of the output code. Since the quantization step Q corresponds to the LSB, it can be said that the resolution coincides with the quantization step Q (and therefore is measured in Volts). We can say that the quantization step Q corresponds to the LSB because two contiguous quantization bands, each of amplitude Q, are identified by codes that differ only for the least significant bit. Resolution (in digital terms): It is the number n of bits present at the co ...

How to use Strings in Python?
Strings in Python, How strings Are Used in python, operators in python, string in input function python, string operations in python, python strings, string in python, strings python
Welcome to the fourth lesson of this python course. Our previous session taught us how to utilize the print function in python, so we have a firm grasp of the terminology and the functions themselves. In this lesson, we'll cover a few more Python terms, such as: Strings Operators Input function Also, we'll build a simple program to print out an imagined dog so that we may better grasp how these concepts are employed. So, let's get started now. Why do we need to understand these terms? Programming is a lot like building a structure out of blocks. Even with just a few types of children's toy blocks and some time and imagination, you can build anything. Because we'll be utilizing these phrases all the time in programming, it's critical that you know what they mean and how to use th ...

Hello friends, in today's post we are gonna have a look at Interfacing of Keypad with 8051 Microcontroller in Proteus ISIS. In the previous project, we have seen the Interfacing of LCD with 8051 Microcontroller and I have told there that LCD is a great debugging tool as we can print our data on it and can display different values and that's what is gonna done in today's post. Today, I will get the values from keypad and then question is how to know that we are getting the correct values. So in order to do so, we will display these values over LCD. So, that's how we are gonna use LCD as a debugging tool. As the debugging is concerned, there's another great tool for debugging which is called Serial port, we can also display these values over to Seri ...

Data security engineer advice for regular Internet users
Data security engineer advice for regular Internet users
We've all heard that clicking on links or attachments can lead to identity theft of sensitive, personal information. And while it's true - if you're not careful, you could be leaving yourself open to hackers and other dangers. But what most people might not know is the difference between "hacking" and "data theft". In this post, we outline the steps data security engineers recommend you take to protect yourself from these different types of threats. What do data security engineers recommend for people who don't work in security? Data security engineers are not your everyday IT professionals, so what do they recommend for parts of the population who aren't working in IT? Data security engineer advice for regular Internet users Step 1: Don't br ...

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at what is DbContext Class in Entity Framework Core. It's our 17th tutorial in ASP.NET Core series. In our previous tutorial, we have discussed Entity Framework Core in detail and have also installed it in our web application. So, now we need understand how to work with Entity Framework Core and for that we have to look at its classes & functions. So, today we will discuss one of its class named DBContext in detail: DbContext Class in Entity Framework Core EF Core contains an important class named DbContext, which is mainly responsible for communication between Database & software objects. We communicate with our database using this DbContext class ...

While Loop in Python
While Loop in python, python while loop, while loop in python, how to use while loop in python, while loop python, while in python, python while, while python
Welcome to the next lesson of our python programming class. In the last session, we looked at the use of If-else statements and created simple programs to demonstrate the concept. While loops are another type of conditional statement, and in this tutorial, we'll look at how they're used. What will you learn? In this article, you'll learn how to prematurely exit a while loop, a Python control structure for endless iteration. You will also learn how to write conditions in a single line to produce short and readable code. Iteration in while loop The term "iteration" refers to the practice of repeatedly running the same piece of code. A loop is a type of programming structure that implements iteration. Bo ...

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create a Custom Filter in ASP.NET MVC. It's our 10th tutorial in ASP.NET MVC series. In our previous tutorial, we have cleared our concepts about Filters in ASP.NETMVC and we have also implemented one built-in filter of ASP.NET MVC. Now, its time to have a look at How to Create a Custom Filter in ASP.NET MVC, in which you can specify your own authentications or handling etc. In our ASP.NET applications, we have use custom built filters a lot for different purposes. So, let's have a look at How to Create a Custom Filter in ASP.NET MVC: Create a Custom Filter in ASP.NET MVC In ASP.NET MVC, custom filters are handled by a base class named as ActionFil ...

Hello friends, hope you all are fine and having fun with your lives. In today's post, I am going to share Interrupt based Digital clock with 8051 Microcontroller. In the previous post, I have explained in detail How to use Timer Interrupt in 8051 Microcontroller. We have seen in that post that we can use two timers in 8051 Microcontroller which are Timer0 and Timer1. Using these timers we can easily generate interrupts. So, before going into details of this post, you must read that timer post as I am gonna use these timer interrupts in today's post. After reading this post, you will also get the skilled hand on timer interrupt and can understand them more easily. In today's post, I am gonna design a digital clock which will increment after every o ...

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create Views in ASP.NET Core MVC. It's our 8th tutorial in ASP.NET Core series. In our 6th lecture, where we have set up MVC architecture, we have also created Controller & Model, but we haven't yet created any View to display this data properly. We have also seen Dependency Injection and have successfully injected Model Interface in our Home Controller.  So, now it's time to add a View in our project and communicate it with Controller & Model. So, let's get started with Views in ASP.NET Core MVC: Views in ASP.NET Core MVC View in ASP.NET Core ( File Extension: .cshtml ) is a simple HTTP template, which displays the Model data, provided by ...
