Why do you need the MISRA Compliance report and how to generate one in PVS-Studio?

If you are strongly interested in MISRA and would like to understand whether your project meets one of the MISRA association's standards, there is a solution. It's name is MISRA Compliance.

Why do you need the MISRA Compliance report and how to generate one in PVS-Studio?

by Nikolay Mironov

From the article:

To make this simpler, let's take rule 1.1 that has the standard value of the category equal to Required. If you look at the table, you can see that acceptable compliance values for Required are Compliance or Deviations (I'll talk more about the meaning of these statuses later). This means that if your project complies with rule 1.1, or if it complies with this rule with some deviations - everything is fine and you can go to the next rule. If you get at least one hit in Violations or Disapplied, then the project does not comply with MISRA C 2012. If all rules have acceptable values only, congratulations! Your project complies with the MISRA C 2012 standard. If you have a hit in the red zone (the table above), you do not comply with the standard.

Integrating PVS-Studio into uVision Keil

I've been using this scenario until one day I spent 3 days debugging a very unpleasant bug. The bug kept savagely appearing from time to time. It turned out to be a banal null pointer dereference. I quickly realized that PVS-Studio detects this bug. That was the final nail in the coffin of my patience! – and started integrating PVS-Studio into Keil.

From the article:

Keil provides a weird feature – creating a project batch file. I still don't know the purpose of this feature. This batch file contains all the necessary information for PVS-Studio, and it's enabled with a single check mark! Unfortunately, this check mark also breaks the incremental build. That is, any compilation becomes a complete recompilation. It affects the build time, so, unfortunately, it's not an option for us.

PVS-Studio Integration in PlatformIO

Recently, the PlatformIO development environment of embedded systems has supported PVS-Studio. In this article, you'll find out how to check your code with the static analyzer on the example of open project.

PVS-Studio Integration in PlatformIO

by Alexey Govorov

From the article:

In the /arduino/AP_Utils/examples/ directory, there are several examples of programs for configuring and running the hexapod, we'll use servo_test.ino. Basically, the program for Arduino is created as sketches in the INO format, which in this case is not quite suitable. In order to make the correct .cpp file from it, it is usually enough to change the file extension, add the #include <Arduino.h> header at the beginning, and make sure that functions and global variables are declared before accessing them.

Embedded systems: Bare metal programming

By Madrid C/C+

In Spanish from the event brief: 

Acabamos el año con uno de los meetups más esperados de la temporada: sistemas embebidos. Nos adentramos en un terreno inexplorado por muchos de nosotros, pero que tienen gran relevancia en el mundo industrial: IoT, domótica, industria del automóvil,...

Meeting Embedded 2018 is a one day event focused on hard and software development for embedded and the IoT. Meeting Embedded will be at Vienna House Andel's Berlin Hotel on the 14th of November, right in front of Meeting C++!

Static Code Analyzer PVS-Studio 6.22 Now Supports ARM Compilers (Keil, IAR)

Now our articles have every chance to become even more interesting because PVS-Studio can now check the code of embedded devices. We have added support for a few ARM compilers, which I talk about in detail below.

Static Code Analyzer PVS-Studio 6.22 Now Supports ARM Compilers (Keil, IAR)

by Andrey Karpov

From the article:

I find the RT-Thread operating system a perfect candidate to be the first embedded system checked with PVS-Studio. I glanced through the analysis report by PVS-Studio and picked 95 warnings that I thought to be the most interesting ones. Too see all those messages for yourself, download the rt-thread-html-log.zip archive with the full HTML report. We introduced this format not so long ago, and some users may not know about it. So, I'd like to use this opportunity to explain it once again.
