floats in big-endian format. Mixed-endian
systems (different layout for ints and floats)
are currently not supported.
-NANOPB_INTERNALS Set this to expose the field encoder functions
- that are hidden since nanopb-0.1.3. Starting
- with nanopb-0.2.4, this flag does nothing. Use
- the newer functions that have better interface.
+PB_NO_PACKED_STRUCTS Disable packed structs. Increases RAM usage but
+ is necessary on some platforms that do not
+ support unaligned memory access.
PB_ENABLE_MALLOC Set this to enable dynamic allocation support
in the decoder.
PB_MAX_REQUIRED_FIELDS Maximum number of required fields to check for
max_size Allocated size for *bytes* and *string* fields.
max_count Allocated number of entries in arrays
(*repeated* fields).
+int_size Override the integer type of a field.
+ (To use e.g. uint8_t to save RAM.)
type Type of the generated field. Default value
is *FT_DEFAULT*, which selects automatically.
You can use *FT_CALLBACK*, *FT_POINTER*,
packed_struct Make the generated structures packed.
NOTE: This cannot be used on CPUs that break
on unaligned accesses to variables.
+skip_message Skip the whole message from generation.
+no_unions Generate 'oneof' fields as optional fields
+ instead of C unions.
+msgid Specifies a unique id for this message type.
+ Can be used by user code as an identifier.
