Most tutorials cover the basics, but they often miss the specific simulation quirks that cause projects to fail in Proteus. Default Address: Often 0x40 (Write) / 0x41 (Read)
The standard Proteus library does not always ship with a native I2C LCD model. Users often simulate using a standard LCD + a separate PCF8574 chip. The "exclusive" version implies an all-in-one, pre-compiled model that behaves exactly like the physical I2C backpack.
