menuconfig NANOPB
bool "Nanopb Support"
help
This option enables the Nanopb library and generator.
if NANOPB
config NANOPB_ENABLE_MALLOC
bool "Malloc usage"
help
This option enables dynamic allocation support in the decoder.
config NANOPB_MAX_REQUIRED_FIELDS
int "Max number of required fields"
default 64
help
Maximum number of proto2 required fields to check for presence.
Default and minimum value is 64.
config NANOPB_NO_ERRMSG
bool "Disable error messages"
help
Disable error message support to save code size. Only error
information is the true/false return value.
config NANOPB_BUFFER_ONLY
bool "Buffers only"
help
Disable support for custom streams. Only supports encoding and
decoding with memory buffers. Speeds up execution and slightly
decreases code size.
config NANOPB_WITHOUT_64BIT
bool "Disable 64-bit integer fields"
help
Disable support of 64-bit integer fields, for old compilers or
for a slight speedup on 8-bit platforms.
config NANOPB_ENCODE_ARRAYS_UNPACKED
bool "Encode arrays unpacked"
help
Encode scalar arrays in the unpacked format, which takes up more
space.
Only to be used when the decoder on the receiving side cannot
process packed arrays, such as protobuf.js versions before 2020.
config NANOPB_VALIDATE_UTF8
bool "Validate UTF-8"
help
Check whether incoming strings are valid UTF-8 sequences.
Adds a small performance and code size penalty.
