Using PCF8563 with UNO R4

Hi, All

I got the code base on below url, after compile and upload , but no output ?

Does this code work with R4 ?

Welcome to the forum

Which Uno R4 board do you have ?
I ask because the forum category that you have posted in is for problems with the installation and use of the IDE itself. Once I know which board yo have the topic will be moved to a more relevant forum category

Please post your sketch, using code tags when you do

Posting your code using code tags prevents parts of it being interpreted as HTML coding and makes it easier to copy for examination

In my experience the easiest way to tidy up the code and add the code tags is as follows

Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.

It is also helpful to post error messages in code tags as it makes it easier to scroll through them and copy them for examination
