    Hi
    I built the RTC-Matrix and it works somehow. The display pops up, shows TMP, day of week and the time. The colon and the heart blink. Thats all. Initially the RTC was set up, but it stopped in that time and date??!!
    I guess there is some code in the main loop missing or wrong. I copied the text above.

    Can you help me?

    Martin
