Dashcam Controller
FirmwareKeep parking-mode changes stable through ignition
Dashcam Controller runs on an Arduino adapter between a Viofo HK3 hardwire kit and the camera. It smooths rapid ignition changes and holds the accessory signal off long enough for the dashcam to recognize parking mode.
Build the adapter, flash the Arduino and fit it into the accessory cable. The project documents the HK3 wiring rather than a list of supported camera models. It keeps the HK3 low-voltage protection in the circuit, and removing the adapter restores the original connection.
- Ignition signal debounce
- Configurable parking transition delay
