2@code_uid{qp_config.h,Sample @QPX configuration file}
3@code_litem{Details}
4This an example of a @QPX configuration file with the explanation
5of the available configuration macros. The `qp_config.h` file
6is optional and does not need to be provided (see the description of
7the #QP_CONFIG macro below). In that case, all the listed configuration
8macros will be set at their __default__ values.
9
10@attention
11The `qp_config.h` configuration file takes effect only when the
12command-line macro #QP_CONFIG is defined.
13
14
15Also, if the `qp_config.h` file is provided and enabled (by defining
16the command-line macro #QP_CONFIG), but any of the listed configuration
17macros is not defined in the provided file, the __default__ value
18will be used.
19
20@note
21Some of the configuration macros listed in this file apply only
22to specific @QPX ports.
23
24@code_litem{Configuration Wizard support}
25The `qp_config.h` header files provided in the various @ref exa "@QPX examples"
26are formatted to support the "Configuration Wizard" editor available in some IDEs
27(e.g., KEIL uVision). The screen shot below shows how to edit `qp_config.h`
28in that mode.

40@code_uid{::QP_API_VERSION,QP Framework API backwards-compatibility version}
41@code_litem{Details}
42QP API backwards compatibility with the @QPX API version.
43Lower `QP_API_VERSION` values enable backwards compatibility
44with lower (older) QP API versions.
45
46- 0 => maximum supported compatibility
47- 580 => QP 5.8.0 or newer
48- 660 => QP 6.6.0 or newer
49- 691 => QP 6.9.1 or newer
50- 700 => QP 7.0.0 or newer
51- 9999 => Latest QP API only (minimum compatibility)
52
53For example, `QP_API_VERSION==691` will enable the compatibility
54layer with QP version 6.9.1 and newer, but not older than 6.9.1.
55`QP_API_VERSION==0` enables the maximum currently supported
56backwards compatibility. Conversely, `QP_API_VERSION==9999` means
57that no backwards compatibility layer should be enabled.

66@code_litem{Details}
67Defining the macro `Q_UNSAFE` disables QP FuSa Subsystem, which
68consists of the following facilities:
69- Software assertions as a recommended technique
70 (called Failure Assertion Programming (FAP) in IEC 61508)
71- Software Self-Monitoring (SSM), which encompasses such techniques:
72 + Duplicate Inverse Storage for critical variables
73 + Memory Markers for critical objects (e.g., events)
74 + Explicit iteration bounds for all loops
75 + Memory Isolation by means of Memory Protection Unit (MPU)
