 Судя по эксперименту, даже через час после пропадания сигнала точность определения события - не хуже 1мс. Сам GPS-приемник выдает
 PPS даже при отсутствии спутников - лишь бы он успел "подхватить" точное время и начать генерировать pps. Начинать работу можно сразу,

-TRIG4 - аналоговый вход. Если будут ложные срабатывания на девбордах, порт PB0 нужно напрямую или через резистор до 10кОм посадить на землю.
 
 Иногда бывают ложные срабатывания триггеров TRIG0..TRIG2, связанные с мощными источниками искр (зажигание, искрящиеся обмотки и т.п.). 
 В случае таких ложных срабатываний рекомендуется заземлить катод источника питания хронометра.

+Хронометр эмулирует "китайский" преобразователь PL2303.
-В андроиде работает "из коробки". В мастдайке новые драйвера PL2303 имеют защиту от подделок (те просто не работают с этими дровами),
-поэтому для нормальной работы необходимо найти и установить старые драйвера.
 
 К выходам PA9/PA10 можно подключить преобразователь USART<>USB или накинуть их напрямую на ноги Rx/Tx "малинки" (не забыв соединить
 земли хронометра и малинки): PA9(Tx) соединить с Rx, PA10(Rx) - с Tx. Этот USART проксирует RMC-сообщения GPS-приемника (уже после
 обработки микроконтроллером, поэтому если МК выключен, а приемник включен, сигнала все равно не будет).
 
-Для подключения PPS сигнала к "малинке" нужно напрямую соединить соответствующую ногу GPIO "малинки" с портом PA1 девборды. 
+Для подключения PPS сигнала к "малинке" выведен соответствующий разъем.
-На прототипе нужно подпаяться к дорожке, выходящей с ноги PPS (отмечено маркером).
-
-Подтяжка USB есть лишь на прототипе, на девбордах ее нет. Поэтому в случае перезагрузки микроконтроллера девборды для возобновления
-соединения необходимо переткнуть шнурок USB. В этом плане прототип надежней: сбросить МК можно независимо от питания GPS.
-
-На прототипе и девбордах отсутствует подсоединение пищалки. На девбордах при желании можно накинуть на PC13 что-нибудь для индикации
-срабатывания створа (активный выход - "1" в течение 0.3с).
-
-На девбордах не распаяны светодиодные индикаторы. Особого смысла в них нет, но если понадобится подключить, нагрузка должна висеть на
-PB8/PB9. Активный выход - низкий. Нога МК настроена в режиме open-drain, но внешняя подтяжка не должна быть выше +3.5В. И потребление

-В случае необходимости срабатывания по подтяжке к земле, нужно разорвать землю на входах опторазвязок и, наоборот, объединить плюсы.
-На плюсы подать +12В, минусы подключить к сигнальным выходам створов.

-На прототипе распаяны развязки только на два канала: TRIG0 - для подключения чего-то, замыкающего контакты, и TRIG2 - для подключения
-чего-то, выдающего 12В. Я оставил такую конфигурацию: к TRIG0 можно подключить нормально замкнутую кнопку (triglevel01), а TRIG2
