Hello dear programmers, I would need help using the RTC DS3231. Would it be possible to use the nodes rtc-device, write and rtc in a patch? Since I would like to use buttons to enter the date-time and write in the clock and read out as the next step for the pixel animation. 1 Clock is the Mainpatch 2. rtc-clock-read-write is complete rtc patch (new node) in the picture the upload fails. I copy the nodes and copy them into the main patch (clock) I can upload the entire nodes and write and read works.

It’s worked out. I think it was the address ports. I have set out for rtc and write node seperate address ports. 🙂 ![Worked](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/b/ba6b04fa0f1f8e9ab49c1661cd0971172cc8b5af.png)
