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
