# undef_rfid | ||
RFID-считыватель [undef.space](https://undef.club) | ||
|
||
# Что делает? | ||
Впускает админов в спейс по картам MIFARE. Аутентификация происходит по номеру | ||
карты Тройка или по UID любой другой карты. | ||
|
||
# Документация | ||
Устройство состоит из: | ||
- отладочной платы на базе ESP32-C3 | ||
- NFC-считывателя на базе PN532 | ||
- платы реле | ||
- держателя | ||
|
||
## Использование | ||
Поднесите карту к считывателю. Если авторизация прошла успешно, светодиод | ||
загорится зелёным, устройство откроет дверь и зафиксирует факт входа в админской | ||
беседе. Если нет - светодиод загорится красным. | ||
|
||
## Администрирование | ||
Чтобы использовать встроенный REPL, подключите устройство по USB и откройте | ||
монитор порта (например, при помощи `idf.py monitor`). Если любая из команд | ||
`add`, `remove` или `list` используется впервые за последние пять минут, нужно | ||
будет ввести пароль. Используйте `help`, чтобы узнать список команд с | ||
аргументами. | ||
|
||
Формат `credential`: | ||
- `T<10 цифр>` - карта Тройка | ||
- `U<8 hex-цифр>` - любая карта с 4-байтовым UID | ||
- `U<14 hex-цифр>` - любая карта с 7-байтовым UID | ||
|
||
## Сборка | ||
|
||
### Держатель | ||
TODO: | ||
|
||
### Электроника | ||
TODO: | ||
|
||
### Прошивка | ||
Написана на C с использованием ESP-IDF. Чтобы собрать прошивку: | ||
- установите ESP-IDF | ||
- склонируйте репозиторий | ||
- скачайте зависимости: `git submodule update --recursive` | ||
- создайте файл `main/include/secrets.h` со следующим содержанием: | ||
```c | ||
#pragma once | ||
#define WIFI_SSID "название сети" | ||
#define WIFI_PASS "пароль сети" | ||
#define HASS_KEY "ключ API HomeAssistant" | ||
#define REPL_PASS "пароль от REPL" | ||
``` | ||
- получите ключи шифрования: | ||
- если собираете новое устройство, сгенерируйте ключи: | ||
`espsecure.py generate_flash_encryption_key flash_key.bin`, | ||
`espsecure.py generate_signing_key --version 1 signing_key.pem` | ||
- если работаете с уже собранным устройством, получите их от админов и | ||
поместите в корень проекта (файлы `flash_key.bin` и `signing_key.pem`) | ||
- соберите проект: `idf.py build` | ||
- загрузите прошивку: | ||
- в самый первый раз: `idf.py flash monitor` | ||
- в последующие разы, в т.ч. для уже собранного устройства: `./flash.sh` |
