TODOS:
Alles fuer nach Oktober:
Bestimmung der maximale kondensator lade zeit
Definition fuer minimale Kondensator Spannung
serial kommunikations problem.
Maximal einstellung fuer LED's
Datumsformat angleichen auf unterstrich variante
Temparatur Sensor
MCU Speichern der fehler in NVM (intern / extern)
Babysitter Chargenable
PowerCycle Recovery entfernen
Transferfenster vorher und nachher testen
///////////////////////////////////////////////////
Requested features for first engineering model:
- sysoff transitor switch. Prevents uncontrolled switching on the Vsys turn on the babysitter if the MCU is in hi-z state, if MCU is powered down.
+ solved by Lutz:
Solution using transitor [XXXXX].
- rc filtering or higher pwm frequency is required to suppress LED flicker on video recording.
+ solved by Lutz & Shintaro:
Solution: Changed to a higher PWM frequency.
- SCU watchdog. If the SCU's watchdog gpio doesn't toggles due to system crash, the MCU should cut off the 5V power rail to turning off all 5V component. Turn off all not requierd component.
+ solved by Lutz & Shintaro:
Solution: The SCU requests power on window, by updating the keepalive timer value. If a timeout of the keepalive timer accurse, the 5V powerrail will be turnd off.
- connecting the i2c vibretion motor driver to SCU not MCU
+ solved by Lutz:
Solution: Lutz wrote a new i2c librrary for the vibration motor driver.
- is i2c timeout integrated?
///////////////////////////////////////////////////
Flight mission critical second tier feature requests:
- MCU software watchdog, against full blocking functions.
- hardware based MCU watchdog, to turn off Vsys. counter measures latch-up failure of the MCU.
- MCU memory check
- ignition retry count set by serial config
- ignition tresholds
- preventing a overflow of the MCU's millis counter
- state machine index self healing feature
- retry count self healing feature
- storing last state index in eeprom
- Thermal managment
- hardening against cosmic radiations
- Serial send echo back for sucssesful transmition
