Ladybug5+ Firmware Release Notes

Release 1.21.3-00

Bugs Fixed

[1] FIRM-8884 - Fixed issue after memory channel load, camera would always trigger on negative edge regardless of previously saved polarity configuration in memory channel. Loading memory channel will now correctly load & set the trigger polarity to saved memory channel value.

[2] FIRM-9514 - Fixed issue where camera timestamping may jump backwards in time with GPS Time Sync enabled. This was caused by camera accepting erroneous GPS input on sync loss. Added further checks for GPS string quality and valid bits to determine GPS input usage on sync loss.

Changes

[1] FIRM-5238 - Added additional quality check logic for incoming GPS sentence parsing on camera. Camera will now perform it's own internal calculation of checksum value for all parsed GPS sentences and compare against existing checksum field in NMEA GPS sentences. If value of calculated checksum does not match incoming GPS checksum, the camera will update the GPS Quality field with value 15 and discard incoming GPS sentence from usage.

[2] FIRM-5238 - Added additional quality check logic for incoming PPS signal. Camera will now perform an internal jitter calculation on all incoming PPS signal. If incoming PPS signal exceeds jitter of +/- 500 ppm, PPS signal will be considered invalid. Logic has changed to also first require a valid PPS signal before parsing and usage of any incoming GPS information.

[3] FIRM-9189 - Added feature for configurable PPS polarity latching. Previously PPS will only latch on transition from Low -> High signal (High Polarity). Now PPS may be configured to also latch from High -> Low signal (Low Polarity). This feature will be configurable through the PPS Ladybug register.
