FS8x driver can use a mechanism to validate data coming from upper software layers (application code) by performing
50
a number of checks on input parameters' range or other invariants that can be statically checked (not dependent on
51
runtime conditions). A failed validation is indicative of a software bug in application code, therefore it is important
52
to use this mechanism during development.
53
54
The validation is performed by using FS_ASSERT macro.
55
A default implementation of this macro is provided in this file. However, application developers can provide their own
56
implementation in a custom file. This requires defining the CUSTOM_DEVASSERT symbol with the specific file name in the
57
project configuration (for example: -DCUSTOM_DEVASSERT="custom_devassert.h")
58
59
The default implementation accommodates two behaviors, based on DEV_ERROR_DETECT symbol:
60
- When DEV_ERROR_DETECT symbol is defined in the project configuration (for example: -DDEV_ERROR_DETECT), the validation
61
performed by the FS_ASSERT macro is enabled, and a failed validation triggers an infinite loop.
62
This configuration is recommended for development environments, as it prevents further execution and allows investigating
63
potential problems from the point of error detection.
64
- When DEV_ERROR_DETECT symbol is not defined, the FS_ASSERT macro is implemented as no-op, therefore disabling all validations.
65
This configuration can be used to eliminate the overhead of development-time checks.
66
67
It is the application developer's responsibility to decide the error detection strategy for production code: one can opt to
68
disable development-time checking altogether (by not defining DEV_ERROR_DETECT symbol), or one can opt to keep the checks
69
in place and implement a recovery mechanism in case of a failed validation, by defining CUSTOM_DEVASSERT to point
70
to the file containing the custom implementation.
