8-bit computer in an FPGA Arduino controller and programmer

8-Bit Computer Arduino Programmer

This post is about the Arduino programmer I made for the 8-Bit Computer in an FPGA. I will show how to use it, connect it, and briefly explain how it works. If you are interested in the source code you can get it all here on Github. This programmer should also be compatible with a normal breadboard computer like the one Ben Eater made in his video series.

8-Bit Computer Flip-Flop Design

In this post, we’ll take a look at the flip-flop which is one of the most common and essential logic blocks used in digital logic design. It can be used used for lots of different things. If you take a look at my 8-bit computer build you will see that flip-flops are used all over the place. 

You can use premade flip-flops provided in Quartus. However, I wanted to build my own from scratch to truly understand how they work.

8-Bit Computer In An FPGA

This project of mine was inspired by Ben Eater and the 8-Bit breadboard computer he made. I would in fact highly recommend you check out his complete video series on it. When I first saw his computer on Hackaday I thought it was awesome and immediately wanted to build my own.

C# Code Snippets String Interpolation

C# String Interpolation

In this tutorial, we will take a look at string interpolation in C#. To enable string interpolation put the $ character before the string. Now variables in brackets can be put straight into a string. This is a bit more convenient compared to splitting up as string, putting the desired variables in between the strings and than concatenating it all together.

C# Code Snippets @ and String Literals

C# @ And String Literals

In this tutorial, we will take a look at string literals and the @ character in C#. In C# the @ character can either be used to make reserved keywords available as variable names or it can be used to make a string literal. A string literal takes everything in the string literally. For example, you do not have to escape a \ with \\ . Your string can now also span multiple rows in the editor. This can be useful when making SQL statements or HTML, XML, …

C# Code Snippets Break and Continue

C# Break and Continue

In this code snippet, we will take a look at break and continue in C#. break is used to break out of a code block. If done in a loop it will essentially stop the loop from executing. continue is used to inside a loop to skip the current iteration.

C# Code Snippets goto Keyword

C# goto Keyword

In this code snippet, we will take a look at the goto keyword in C#. goto is used to move the control of your program to a label you define beforehand. This can be useful to get out of nested loops, if statements or any nested code blocks in general. You can even make a DIY loop or method using the goto keyword 😁(But you should of course use the regular loops and methods).

C# Code Snippets TPL(Task Parallel Library) and Tasks

C# TPL(Task Parallel Library) And Tasks

In this code snippet, we will take a look at the TPL(Task Parallel Library) in C#. If you read some of my other posts on threading you will know that it can be quite complicated and laborious for the developers to implement parallelism into their programs(deadlocks, cancellation, thread pooling, getting data back from the thread, …). The Task Parallel Library(TPL) takes care of a lot of these things and or makes them easier manage.

C# Code Snippets Thread Pooling

C# Thread Pooling

In this tutorial, we will take a look at thread pools in .NET and C#. Creating threads and disposing of them when a task is done can be an expensive operation to perform as it uses up time and memory. To mitigate this we can use a thread pool which is essentially a collection of pre instantiated threads. We can assign tasks to these threads. When the task is completed the thread gets returned to the thread pool instead of being disposed of.
