Chipkin’s BACnet Stack (CAS BACnet Stack) is a software library that allows you to add a native BACnet interface to your embedded devices or applications. The BACnet stack supports both BACnet server (Field device, power meter, gas detector, etc...) and BACnet client (HMI, Utilities, data loggers, etc.). More information about the CAS BACnet Stack can be found here https://store.chipkin.com/services/stacks/bacnet-stack
See the repositories tab for a full list of CAS BACnet Stack examples in many different programming languages
The CAS BACnet Stack supports every standardized device profile in ASHRAE 135-2024 Annex L, and there is one example repository per profile. Pick the profile your device claims, then the language you build in. "Ask" means the example hasn't been built yet for that language - contact Chipkin if you need one.
