Python Hardware

Blackchirp can drive a hardware device through a user-supplied Python script instead of a compiled C++ driver. A Python driver is selected per profile, the same way a built-in driver is, and each Python-backed hardware type ships with a template script that runs out of the box against the Virtual communication protocol. The Hardware Profiles page covers profile creation in general; this chapter covers the parts specific to Python drivers.

In this chapter

• Overview — architecture and the list of supported hardware types

• Selecting a Python Driver — wiring a script, class name, and Python environment to a profile

• Writing a Python Driver — lifecycle methods, injected proxies, and return-type expectations

• Reloading and Editing a Script — editing and reloading a script from the per-device hardware dialog

• Per-Type Capabilities — methods each trampoline expects from the driver class
