Zobrazení dat ze sériového monitoru i na lcd

[daggo]

Dobrý den, chtěl bych vás poprosit o pomoc. S modulem DCF77 jsem na základě návodu ze stránky: https://navody.dratek.cz/navody-k-produ ... -dcf1.html "zprovoznil" hodiny. Nedaří se mi zprovoznit zobrazování údajů ze sériového monitoru (datum a čas) na LCD I2C 16x2. Zkoušel jsem to i přes chatGPT, bez výsledku. Děkuji předem za pomoc.
Doplňuji: knihovnu LiquidCrystal_I2C mám nainstalovanou, kód, kde se "objevuje" lcd... jsem doplnil já. Když modul chytne signál, na LCD svítí datum: a cas: Ale jak dostat datum a čas do kódu lcd.print, nevím.

V příkladech nemám žádný s výstupem na LCD, jen na sériový monitor.

Co provede tohle ?

    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("datum: ");

Díky za tip, žel program se nenahraje- viz chybové hlášky. Jelikož s ardu začínám, tak nevím jak ty chyby odstranit.

Asi by to mohlo opravit prevedeni těch hodnot na normalní čísla podle tohoto vzoru

BCD::bcd_to_int(time.month);

tedy

lcd.print(aktualniCas.day);

na

lcd.print(BCD::bcd_to_int(aktualniCas.day));

a tak podobně

Děkuji ti za tip, LCD je funkční. Kód jsem upravil - viz níže. Ještě poladím zobrazení celého roku (2025), zobrazuje se jen 25.
Ještě jednou ti moc děkuji.

Ještě bych poprosil o pomoc. Nadefinoval jsem, od jakého místa na LCD se bude zobrazovat čas i datum. Z estetického hlediska bych byl rád, kdyby se čísla u času zobrazovala ve tvaru hh:mm:ss a datumu dd.mm (rok už mám vyřešenej). Na sériové lince to je v pořádku.
Zkoušel jsem to podmínkama (if), co jsem ponacházel různě na netu, bezúspěšně.
Ještě doplňuji, že je toto můj první rozumný projekt v arduinu. Blikání LEDkama mě už omrzelo )

Ahoj, zrovna na takovíhle doladění funkčního kódu používam AI nejvíc a de jí to nejlíp. Hodíš kus kódu řekneš co chceš přidat a přidá. Celkové programování zvládá taky ale chce to postupně a věci si dodělávat sám.
Ať se daří

[daggo]

Zdravím, a děkuju za funkční radu od AstroMiKa (zkusmo jsem to pak zkusil i přes ChatGPT a dostal jsem stejný výsledek).
Ještě jednou děkuji všem, kteří mi pomohli. Mějte pěkné dny.
