Detailed Description

Sample QP/C configuration file.

Details
This an example of a QP/C configuration file with the explanation of the available configuration macros. The qp_config.h file is required for every QP/C Application.

Attention
The qp_config.h file is required for every QP/C Application.
Remarks
Some of the configuration macros listed in this file apply only to specific QP/C ports.

Configuration Wizard support
The qp_config.h header files provided in the various QP/C examples are formatted to support the "Configuration Wizard" editor available in some IDEs (e.g., KEIL uVision). The screen shot below shows how to edit qp_config.h in that mode.

Macro Definition Documentation

◆ QP_API_VERSION

#define QP_API_VERSION   0

QP/C Framework API backwards-compatibility version.

Details
QP API backwards compatibility with the QP/C API version. Lower QP_API_VERSION values enable backwards compatibility with lower (older) QP API versions.

  • 0 => maximum supported compatibility
  • 580 => QP 5.8.0 or newer
  • 660 => QP 6.6.0 or newer
  • 691 => QP 6.9.1 or newer
  • 700 => QP 7.0.0 or newer
  • 9999 => Latest QP API only (minimum compatibility)

For example, QP_API_VERSION==691 will enable the compatibility layer with QP version 6.9.1 and newer, but not older than 6.9.1. QP_API_VERSION==0 enables the maximum currently supported backwards compatibility. Conversely, QP_API_VERSION==9999 means that no backwards compatibility layer should be enabled. Default: 0 (All supported)

◆ Q_UNSAFE

#define Q_UNSAFE

Disable the QP Functional Safety (FuSa) Subsystem.

Details
Defining the macro Q_UNSAFE (in the application-specific qp_config.h header file) disables most of the QP FuSa Subsystem, affecting the following facilities:

  • Software assertions as a recommended technique (called Failure Assertion Programming (FAP) in IEC 61508)
  • Software Self-Monitoring Safety Functions, which encompasses such techniques:
    • Duplicate Inverse Storage for critical variables
    • Fixed Upper Loop Bound for all loops
    • Invalid Control Flow for all unreachable code paths

The intent of the Q_UNSAFE macro is to support verification (during development) that assertions (and more generally, Safety Functions) have no side effects on the primary functionalityare and are truly independent from the nominal flow of control.

However, quite specifically, the Q_UNSAFE macro should not be used to permanently disable the QP/C FuSa Subsystem in the final, production release of the QP/C Application, especially in the context of a safety-related system.

Attention
Disabling QP FuSa Subsystem (by defining the macro Q_UNSAFE) in the final production release, contradicts the most fundamental principles of functional safety and is not allowed in safety-related applications.
