v1.1.0 - Multi Device support; EL15 now supported

What's new in v1.1.0

Alientek EL15 Electronic Load support

• All measurement modes: CC, CV, CR, CP, CAP, DCR
• Advanced modes: POW [A], POW [DT], ADV [L], ADV [S], POW [RPT]
• Live voltage waveform with V/I/P tooltip
• Protection fault display — reverse polarity (REV) and undervoltage (UVP) shown directly in the UI
• Fan speed, temperature, runtime, and setpoint readout

Improvements

• Raw packet log no longer hijacks scroll position when you've scrolled up (behaves like a terminal now)
• Waveform tooltip order: value → extra metrics → timestamp

Internal

• Refactored into a multi-device framework; DM40 behaviour unchanged

Full Changelog: v1.0.1...v1.1.0

v1.0.1 - Fixed Temp measurements, C FFI cleanups

Highlights

• Fixed Temp Measurements: Corrected temperature parsing/display so primary, secondary and tertiary readings appear correctly (closes #1).
• Performance: Low-level optimizations (initialize types once; replace heavy ComPtr patterns with release_ptr; optimize _vtbl_invoke and _ComDelegate), yielding significant speedups.
• Stability & Cleanup: Cleaner radio state handling (fewer Python↔C transitions), removed unused WinDLL calls and other robustness improvements.
• API / Interop: Added an addressof forward export to help low-level interop.
• Miscellaneous: Return empty list instead of None when no devices present; prefer % formatting for hex.

Notable commits

• 1b6fcb9 (2026-03-20) — Fixed Temp measurements (closes #1)
• c657cec (2026-03-20) — Cleaned up radio state handler: fewer Python↔C transitions; disabled unused WinDLL get-last-error; removed pointless try/finally
• dd41df3 (2026-03-20) — Prefer % string formatting for HEX
• 6892bc4 (2026-03-20) — Type cleanup & optimizations
  • init types once
  • replace ComPtr+release with release_ptr
  • optimized _vtbl_invoke (~2.5×) and _ComDelegate (~5×)
• b6c291c (2026-03-19) — Add addressof forward export
• 1e686eb (2026-03-19) — Fix linter warning; return empty list if devices is none
