Does CCES have any API that can be used to build automation test platform with Python other than CCES_Runner.exe?
Unfortunately, the Scripting interface that was in VisualDSP++ is not presently available in CCES. We do not currently have a timescale for the implementation of such a feature.
CCES Runner is a command line utility that only can be used to help automate tests in CCES. Since CCES doesn't have any automation API's as in VisualDSP++.
We offer headless tools to create and build projects using a command line(see CrossCore® Embedded Studio <version> > Integrated Development Environment > Command Line Build Support in the CCES help), and CCES_runner to run them.
