WARNING: THIS REPOSITORY IS ARCHIVED. DEVELOPMENT CONTINUES IN THE PORTAL300 monorepo.
This repository implements an interface to the Busch Welcome installed in the Ulmer Straße 300.
This code is part of the project Portal 300, the new portal infrastructure for shackspace.
The microcontroller board for this project is the WT32-ETH01 which has a LAN 8720 PHY installed.
More information on this board can be found in this repository.
- The ESP32 will interface network via RMII ethernet
- IO39 is used as an output to press the "Open Door" button and unlock the front door.
- IO15 is used as an input, responding to the door bell.
We created a small adapter board that is sitting on top of the WT32-ETH01:
The wire colors transport the following signals:
| Wire | Signal |
|---|---|
| gray | GND |
| orange | Power Supply (5V) |
| yellow | doorbell was triggered (gray ist reference GND) |
| brown | emitter for "Open Door" button |
| purple | collector for "Open Door" button |
