timer/tijdklok

Bericht door 19roland70 »

even stukje uitleg ik wil een tijdklok maken die het volgende moet doen: 4 timers die op tijdbasis werken 2 uitgangen die temperatuur gestuurd zijn als tijdbasis heb ik een ds1307 met een ds32kHz en temperatuur een ds1621 microprocessor is een 16f877 display 4 x 20 en paar drukknoppen voor instellingen nu mijn probleem ; Ik krijg wel apart de temp op het display maar niet samen met de tijd weet iemand hiervoor een oplossing ook om de timers in te stellen?

Kan je de code die je al hebt ook even posten? Dan kunnen we zien waar het "mis" gaat.

ik denk dat dit heeft te maken met een conflict op de I2c bus als ik de schakelingen apart ( 1voor 1) opbouw dan werkt het wel

Met de pinnen A1 en A2 kan je een adres instellen. Die heb je toch niet hetzelfde staan? Anders kan je proberen 1 van de 2 dingen op 2 aparte pinnen te hangen en een aparte software I2C bus te programmeren.
