PVS-Studio is a static code analyzer detecting errors and potential vulnerabilities in the code of applications written in C, C++, and C#. We've been entertaining the readers of our blog for a long time by checking various open-source projects and commenting on the bugs found. 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. Bugs in embedded devices and robots could be more of a spectacle than bugs in regular applications. When showing up in such devices, bugs don't simply cause a program to crash or hang, or display an image incorrectly; they make Wi-Fi kettles go mad and boil the water until it's all gone and the thermostat trips. That is, bugs tend to be more interesting and creepy in the world of embedded systems.
