# doorman2: electric boogaloo

- `esp32/` contains the micropython source which talks w/ NFC module and keypad over UART (two channels)
- `keypad/` has some magical Arduino code (sorry)

## syncing data from LDAP

big TODO; currently, you need to:
1. clone the old doorman repo and patch the `doorman_ldap_sync` file (see my shitty patch attached below)

```

     to_remove = cur - target
     to_add = target - cur
```

2. launch the script, copy all the lines with the hashes and save them a file
3. `mpremote fs cp hashes :hashes`

plans: web UI like vuko's design

## esp <-> keypad protocol definition

- one byte per command, no delimeters, keypad is supposed to be as stateless as possible
- the keypad can only send numbers and the hash symbol
- ESP can send the following commands:
	- `H` ("happy" noise, success; turns on the green LED for a second and turns it back off)
	- `S` ("sad" failure noise; likewise with the red LED)
	- `F` ("flush"; turns off LEDs and tries to bring the env to a sane level)
	- `G`, `R` ("green", "red"; turns on the specific LEDs)
	- `Q` ("quiet"; turns on audible keypresses)

i am so sorry
