Splits hardware-test concerns into two reusable modules and rebuilds
test_mum_alm_animation.py on top of them.
- frame_io.py — generic LDF-driven I/O class. Knows nothing about
ALM. Three access levels:
high: send/receive/read_signal by frame and signal name
mid: pack/unpack — bytes ↔ signals without I/O
low: send_raw/receive_raw — bypass the LDF entirely
Plus introspection: frame, frame_id, frame_length. Frame lookups
are cached per FrameIO instance.
- alm_helpers.py — ALM_Node domain helpers built on FrameIO.
AlmTester class bound to (fio, nad) exposes:
force_off, read_led_state, wait_for_state,
measure_animating_window, assert_pwm_matches_rgb,
assert_pwm_wo_comp_matches_rgb
Plus pure utilities (ntc_kelvin_to_celsius, pwm_within_tol) and
the LED-state / pacing / PWM-tolerance constants. PWM assertions
use vendor/rgb_to_pwm.py (compute_pwm) at the runtime
Tj_Frame_NTC temperature.
- test_mum_alm_animation.py rewritten:
* fio + alm fixtures replace the previous dict-based _ctx
* SETUP / PROCEDURE / ASSERT / TEARDOWN section markers
* test_mode1_fade now wraps its ConfigFrame change in
try/finally so EnableCompensation is restored even on
assertion failure (was leaking state into later tests)
* test_disable_compensation_pwm_wo_comp uses the four-phase
pattern explicitly
Sibling imports work because pytest's default rootdir mode puts the
test file's directory on sys.path.

The MUM (Melexis Universal Master) adapter is the current default; the
BabyLIN SDK adapter is retained only for backward compatibility with
existing rigs.
Code:
- Emit DeprecationWarning when BabyLinInterface is instantiated and
when tests/conftest.py routes interface.type=='babylin' to it.
- Update module/class docstrings in ecu_framework/{__init__,config,
lin/__init__,lin/babylin}.py to label BabyLIN-specific fields and
paths as deprecated.
Config / scripts / pytest:
- pytest.ini: relabel the babylin marker as deprecated.
- config/{babylin.example,examples,test_config}.yaml: add deprecation
banners and field comments.
- scripts/99-babylin.rules and scripts/pi_install.sh: annotate the
udev-rule install block as legacy-only.
Documentation:
- TESTING_FRAMEWORK_GUIDE.md, docs/08_babylin_internals.md, and
vendor/README.md: prepend explicit "DEPRECATED" banners.
- docs/{README,01,02,04,05,07,09,10,12,13,14,15,18,DEVELOPER_COMMIT_
GUIDE}.md: relabel "legacy" to "deprecated" where babylin is
mentioned, present MUM as the primary path, and steer new work
toward the MUM examples.
No tests, configs, or modules were deleted; existing BabyLIN setups
keep working but now produce a clear DeprecationWarning at runtime.
