The Error it keeps on pitching is that macro "min" requires 2 arguments, but only is presented with 1.

the 8 bit integer could, technically, handle 60 minutes, however it wants "mm" not "m" in there. So i grabbed another RTC, and when i did , it broke everything. So i have to re-integrate the original I2C.h

Any solution for this? I am trying to integrate this to step7. And it seemingly would work if there is a Serial Print function for M5Paper. I do not see that available, as it is actually "Canvas Draw" which leads to confusing integration.

Any help would be great, my code is as follows:

Data Read Demo

Created 12 Dec 2016
Modified 10 Mar 2019 for Settimino 2.0.0
by Davide Nardella

This demo shows how to read data from the PLC.
A DB with at least 1024 byte into the PLC is needed.
Specify its number into DBNum variable

• Both small and large data transfer are performed (see DO_IT_SMALL)
• During the loop, try to disconnect the ethernet cable.
  The system will report the error and will reconnect automatically
  when you re-plug the cable.
• For safety, this demo doesn't write data into the PLC, try
  yourself to change ReadArea with WriteArea.
• This demo uses ConnectTo() with Rack=0 and Slot=2 (S7300)
  • If you want to connect to S71200/S71500 change them to Rack=0, Slot=0.
  • If you want to connect to S7400 see your hardware configuration.
  • If you want to work with a LOGO 0BA7 or S7200 please refer to the
    documentation and change
    Client.ConnectTo(<IP>, <Rack>, <Slot>);
    with the couple
    Client.SetConnectionParams(<IP>, <LocalTSAP>, <Remote TSAP>);
    Client.Connect();
