v32.00-beta

Summary of Changes Since 31.09-beta

Firmware Changes (Version 31 → 32)

Runt pulse rejection for the trigger system

• Visual lines (draggable!) showing trigger thresholds, delta, runt delta, ToT, and holdoff

Zoom window improvements

• ROI synced crosshairs between main and zoom windows

Firmware version checking

• Software now validates firmware version compatibility, prevents using newer firmware than software expects

Clock output management

• Enable clkout on all boards at startup (don't assume which is first)

Polynomial filtering bug fix

• Fixed settings loading issue

v31.09-beta

Summary of Changes Since v31.07-beta3
