New in version 4.1.
Automated code analysis without hassle!
Static analysis became an important part of software development cycle. It can identify potential bugs, vulnerabilities and security threats by doing an analysis on the source code level without having to test it on hardware or execute any code.
PIO Check helps reduce development cost by enabling engineers to detect the precise location of defects and eliminate issues more efficiently and earlier in the development cycle. It can also ensure compliance with internal or industry coding standards such as MISRA, CERT, etc.
- Fully integrated within the PlatformIO ecosystem and easy to execute on the entire project.
- Straightforward integration with Continuous Integration services.
- Possibility to reuse the same setup on other projects.
- Easy and flexible rule configuration.
- Comprehensive and detailed error information
- Multiple architectures and development platforms.
- Cross-platform: Windows, MacOS, Linux.
- PIO Check can detect a wide range of known defects in C/C++ code, including:
- Potential NULL pointer dereferences
- Possible indexing beyond array bounds
- Suspicious assignments
- Reads of potentially uninitialized objects
- Unused variables or functions
- Out of scope memory usage
There is the rich and friendly interface for PIO Check in PlatformIO Home. It allows you to filter messages or directly jump to an issue in a source code.
PIO Check allows selecting what tool is used for finding defects in the project, what source files are checked. PIO Check can be configured from “platformio.ini” (Project Configuration File) using the next options:
You can switch between or specify multiple tools used for finding defects using check_tool option:
[env:myenv] platform = ... board = ... check_tool = cppcheck, clangtidy
Detailed information about supported check tools and their configuration process can be found on these pages:
Defect severity is a classification of software defect (bug, vulnerability, etc) that indicates the degree of negative impact on the quality of software. PIO Check uses the next classification of possible defects:
||Issues that are possibly bugs|
||Suggestions about defensive programming in order to prevent potential bugs|
||Issues related to code cleanup and performance (unused functions, redundant code, const-ness, etc)|
