Hi. I want to use time and data from rtc module based on ds1302 chip like in picture below: [RTC-DS1302-MODUL-ZEGAR-CZASU-RZECZYWISTEGO-ARDUINO] I know there is Xod library for rtc module but its for i2c comunication. But module that i have is called 3 wire comunication. It has 5 pins: VCC, GND, …

Hi, can cesars/ds1302 [image] Problems with DS1302 Hello, How to connect ds 1302 to arduino nano? Ds 1302 does not have i2c. In the description of the library ds-rtc nothing is written.

I load your library and try it on two different boards, Nano and Uno, but still cant get any data from RTC module. However it works with sketch from link via Arduino IDE, so the module itself is fine.

I connect everything like in this picture, and go o debug mode: [Bez tytułu] When left button is pressed and released, to set data and hour, it change its status from false to true,and back to false, just like supposed to. When right button is pressed to read data, it change its status from fals…

Anyone else have this module, and can check it with Xod?

You could be having conflict with timers used for serial communication for rtc and debug… Just grasping at straws…

Yes. Its looks like it’s because debug is on. So, I finally make my RTC module work in Xod. I get date, weekday and time from it, and display on LCD: [prt] I use tobias/plc library to format data from module. But there is problem with year and weekday. Year, instead “2020” is “55”, and weekday i…

Hi. What I will say now is more a question than an answer. I don’t have a sensor, and I don’t have the ds1302 and tobias / plc libraries, but why can’t I set a date (without a sensor) in some patch, and after every second add one to this patch? The Patch itself will have functions to convert seconds…

My guess would be that day of week is using 1 for Monday, but rtc-wds is an nth-input which starts at zero, so you need to add an extra pin in front of Monday.

Danya, RTC is used to remember time when Arduino is power cycled and it also keeps more accurate time than counting seconds in software.

If rts-wds is like nth-input, then the number 7 will go beyond nth-input, then it will still show Sunday, not Saturday. [image] So the error is not here. I have a guess that this is due to the year. The day of the week depends on the year.

and as it turned out, the rtc-wds is not a nth-input. [image] [image]
