-/* CONFIG_NSH_BUILTIN_APPS - Build the QE test as an NSH built-in function.
- * Default: Built as a standalone problem
- * CONFIG_EXAMPLES_QENCODER_DEVPATH - The path to the QE device. Default:
- * /dev/qe0
- * CONFIG_EXAMPLES_QENCODER_NSAMPLES - If CONFIG_NSH_BUILTIN_APPS
- * is defined, then the number of samples is provided on the command line
- * and this value is ignored. Otherwise, this number of samples is
- * collected and the program terminates. Default: Samples are collected
- * indefinitely.
- * CONFIG_EXAMPLES_QENCODER_DELAY - This value provides the delay (in
- * milliseonds) between each sample. If CONFIG_NSH_BUILTIN_APPS
- * is defined, then this value is the default delay if no other delay is
- * provided on the command line. Default: 100 milliseconds
