Witajcie!
Jakiś czas temu pytałem już o dwa problemy z RTC i Wasze odpowiedzi ruszyły co nieco. Pojawił się jednak kolejny problem:
RTC stanął i nie działa. Ani na kwarcu, ani na wew. oscylatorze. Już nie jest problem to, że za szybko liczy, czy przeskakuje. Totalnie i w ogóle nie działa. Próbowałem przywracać poprzedni kod, ale nic to nie dało. Czegoś chyba nie wiem....
Program w ogóle nie może zczytać danych z RTC, czy to w formie BIN czy BCD.
RTC został skonfigurowany w CubeMX.
