To build TinyCBOR:
make
If you want to change the compiler or pass extra compiler flags:
make CC=clang CFLAGS="-m32 -Oz" LDFLAGS="-m32"
Documentation: https://intel.github.io/tinycbor/current/
The CBOR(Concise Binary Object Representation) is a binary data serialization format which is similar to JSON but with smaller footprint. This example will illustrate how to encode and decode CBOR data using the APIs provided by tinycbor.
For detailed information about how CBOR encoding and decoding works, please refer to REF7049 or cbor.io;
This example should be able to run on any commonly available ESP32 development board.
Run idf.py -p PORT flash monitor
to build and flash the project.
(To exit the serial monitor, type Ctrl-]
.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
