# [v1.30.0]
eive-tmtc: v2.14.0
Event IDs for PDEC handler have changed in a breaking manner.
## Added and Fixed
- PDEC: Added basic FDIR to limit the number of allowed TC interrupts and to allow complete task
lockups in the case an IRQ is immediately re-raised by the PDEC module. This is done by only
allowing a certain number of handled IRQs (whether they yield a valid TC or not) during
time windows of one second. Right now, 800 IRQs/TCs are allowed per time window.
This time window is reset if a TC reception timeout after 500ms occurs. TBD whether the maximum
allowed number will be a configurable parameter. If the number of occured IRQs is exceeded,
an event is triggered and the task is delayed for 400 ms.

- Patch version which compiles for EM
- CFDP Funnel bugfix: CCSDS wrapping was buggy and works properly now.
- PDEC: Some adaptions to prevent task lockups on invalid FAR states.
PR: https://egit.irs.uni-stuttgart.de/eive/eive-obsw/pulls/393
- CMakeLists.txt fix which broke CI/CD builds when server could not retrieve full git SHA.
- Possible regression in the MAX31865 polling task: Using a `ManualCsLockGuard` for reconfiguring
and then polling the sensor is problematic, invalid sensor values will be read.
