I am currently running a DS1307 and LCD controller. I am having issues with locking up randomly after hours of perfectly fine operation. I tested my 3V battery for the DS1307 and it tested fine.
Do I need “Wire.begin();” in my setup to run I2C? I am currently running without it.
Do I need pull-up resistors on SDA and SCL? Again, not running them right now.
What is the INT pin used for on these devices?
