CBOR
CBOR (Concise Binary Object Representation) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation.
Zephyr provides support for CBOR via the zcbor library, which is pulled in as a West module.
Configuration
To enable CBOR support, enable the CONFIG_ZCBOR Kconfig option.
API Reference
The zcbor library provides its own API documentation, please refer to it for more information.
