@ -36,6 +38,13 @@ will consitute of a breaking change warranting a new major release:
Furthermore, the submode in the NORMAL mode now should be 0 instead of some ON mode submode.
- Updated GYR bias values to newest measurements. This also corrects the ADIS values to always
consit of just one digit.
- The CCSDS IP core handler now exposes a parameter to enable the priority select mode
for the PTME core. This mode prioritizes virtual channels with a lower index, so for example
the virtual channel (VC0) will have the highest priority, while VC3 will have the lowestg
priority. This mode will be enabled by default for now, but can be set via the parameter IF with
the unique parameter ID 0. The update of this mode requires a PTME reset. Therefore, it will only
be performed when the transmitter is off to avoid weird bugs.
- Connect and handle reset line for the PTME core in the software now.
- Safe mode controller failure event now only triggers once per minute.
