muse-driver-framework

Shared pure-Python runtime framework for AMX MUSE Script-as-Device programs.

The package contains the transport-independent pieces shared by the Precis Driver and Meter Validation programs:

• asynchronous TCP connection lifecycle and reconnect handling;
• descriptor control registry and control type inference;
• bounded, latest-only MeterStream frame delivery.

It has no third-party runtime dependencies and supports the Python 3.10 runtime used by current MUSE firmware.

Runtime use in MUSE

Each Script-as-Device program declares the exact framework version in its own requirements.txt:

muse-driver-framework==1.0.0

The program imports the package, never a copied local driver_framework.py:

from muse_driver_framework import AsyncTcpDeviceClient, AsyncTcpDeviceManager

MUSE must have internet access when it installs the requirements file. Keep the version exact so a framework release cannot silently change an existing driver.

Local verification

Build and install the wheel into an isolated environment before testing a driver. The driver directories should not contain a local framework copy.
