at_c

at_c is the alpha C implementation of the atSDK

Packages

• atchops stands for "Cryptographic and Hashing Operations" catered for the atProtocol. atchops uses MbedTLS crypto and other MbedTLS crypto libraries as a dependency.
• atclient implements the atProtocol and will be the core dependency for most applications. atclient depends on atchops and MbedTLS.
• atclient_espidf is a package for helping you build atclient for ESP-IDF (Espressif IoT Development Framework) based projects.
• atlogger is a tiny logging package.

Building Source

Learn how to build atsdk from source code to be used as a library in your projects.

Installing on Linux/MacOS

1. Get ahold of the source code either via git clone or from downloading the source from our releases:

git clone https://github.com/atsign-foundation/at_c.git
cd at_c

2. CMake configure

cmake -S . -B build

3. Install

This will run the install step and install the static libraries and include headers on your system. You may need to use sudo.

cmake --build build --target install

4. Building the source code will allow you to use the atclient library in your own CMake projects:

# myproj is a target in your CMake project that depends on atsdk
find_package(atsdk REQUIRED CONFIG)
target_link_libraries(myproj PRIVATE atsdk::atclient)

The target atsdk::atclient is the atclient library that you can link to your project. It includes atchops and atlogger as dependencies already with it.

Examples
