Termiczna głowica drukująca dla systemu zarządzania parkingiem w oparciu o Raspberry - spikeli - 29-10-2021
Materiały do wykorzystania
1、KAMIEŃ STWI101WT-01
2、Głowica drukarki termicznej FTP
3、Raspberry Pi pico
4、Maszyna obsługiwana przez monetę
Funkcja
Funkcja sterowania jest wyświetlany na ekranie szeregowym, główny interfejs wybiera piętro, po wejściu do głównego interfejsu wybiera miejsce parkingowe, w tym samym czasie będzie wyświetlać numer miejsca parkingowego w polu tekstowym w prawym górnym rogu, a następnie wybiera czas pobytu, to dwa przewijane selektory tekstowe, a następnie również sam będzie wyświetlać informacje o zamówieniu w polu tekstowym w prawym górnym rogu, zgodnie z ustaloną ceną jednostkową, która mnoży się z czasem pobytu, aby uzyskać całkowitą cenę. Następnie tylko wtedy, gdy miejsce parkingowe i czas pobytu są wybrane, można przejść do przycisku płatności, w przeciwnym razie jest to nieważne. Po wejściu do ekranu płatności, zostanie użyty akceptor monet. Następnie na ekranie pojawi się liczba monet do wrzucenia oraz liczba monet już wrzuconych. Po wrzuceniu monet zostanie wyświetlony komunikat o powodzeniu płatności. Następnie można wybrać opcję drukowania małego biletu, aby wydrukować numer miejsca i czas na papierze termicznym.
Obwód
Zaprojektowałem obwód samodzielnie w celu napędzania wielu komponentów, a ogólny schemat obwodu wygląda tak, górny lewy róg to gniazdo komunikacyjne i gniazdo zasilania, poniżej znajduje się brzęczyk (w rzeczywistości nie używany w obwodzie), po prawej stronie znajduje się dioda świecąca, a w prawym dolnym rogu znajduje się 30pin fpc do podłączenia głowicy drukującej.
