The presentation provides an overview of the ChimeraTK framework. The project started from a demand for software libraries that provide convenient access to PCIe bus based cards on the MicroTCA.4 platform. Previously called MTCA4U, ChimeraTK is evolving towards a set of frameworks and tools that enable users to build up control applications, while abstracting away specifics of the underlying system. Initially, the focus of the project was the DeviceAccess C++ library and its bindings for Matlab and Python, along with a Qt based client that used DeviceAccess under the hood. However, ChimeraTK has expanded to include more tools like the ControlSystemAdapter, VirtualLab and ApplicationCore. The ControlSystemAdapter framework focuses on tools that enable application code to be written in a middleware agnostic manner. VirtualLab focuses on facilitating testing of application code and providing functional mocks. The ApplicationCore library aims at unifying application interfaces to other tools in the toolkit and improving abstraction. We present an update on improvements to the project and discuss motivations and applications for these new set of tools introduced into the toolkit.
