Introduction to Yats (Yet Another Test System) Yats is a new project of mine. It is a test framework oriented towards embedded devices. It allows creating repeatable test scenarios from user-defined test cases. The framework is written in C# and can be run on any Windows machine with .NET 3.5 or later. Linux (Mono) support… Read More »
While writing a new bitbake recipe, I stumbled upon this: The recipe is obviously present, but it can not be found by bitbake. Turns out, this is because of an illegal underscore in the recipe name (directory name too). You should use “-“, underscore is used for version separation
On a related note to the previous post, here is a patch that enables the SerialPort.DataReceived event. It is not officially supported in the Linux version of Mono. This workaround works in the following way: When a port is opened, a new thread is started. It polls the port for incoming data and generates the… Read More »
I have been searching for a solution for the missing Mono libMonoPosixHelper.so library. It is necessary in order to use SerialPort class. The application I’m working on now runs on an ARM processor, Linux OS based on OpenEmbedded. I’m not submitting this as a patch because I’m pretty sure this is not the proper way… Read More »
Here is a C# helper class that encrypts and decrypts data using the AES 128-bit algorithm. It can be used (after through testing, of course) to pass data between a .NET application and any other application using OpenSSL. Most of the credit belongs to Deusty blog. I have added a compatible Encrypt method. When encrypting,… Read More »
I decided to switch to Python while developing the embedded client in C language. There was not much work done anyway, and faster coding with Python should allow me to catch up. Luckily the socket part is in working condition. It was tested in Ubuntu Linux and OpenWrt router firmware v8.09 based on 2.4 kernel.… Read More »
I’ve been working on a project that uses the inexpensive and easily obtainable and programmable LCD panel from Nokia 3310 mobile phone. I’m posting some of the source code here because it was quite hard to find a ready-made driver on the web. The code was tested on an ARM-based microcontroller. Add pin definitions, sleep… Read More »
In this part of the tutorial, the source code for creating a Java server socket is given. The server code is deployed as a .jar file. The JAR file also contains the public and private key pair (keystore server.private) and the public key of the client (client.public). The example contains a hard-coded password for the… Read More »
