Hello. One of the advantages of i2c displays vs the "normal" ones is that it needs only 2 wires. I don't care about that one, but i'm looking at better speed performance. The displays are so slow with the LiquidCrystal library...
I have a project where I have one arduino i2c slave with a standard display connected to it, and the master sends over i2c the bytes to be displayed, obviously the slave takes it time to write to the lcd, but the important thing is that the master sends the bytes very fast and it continues to do it's own tasks, while the slave is writing to the lcd.
So the question is, in terms of speed, would it be the same if I used an i2c display instead of an atmega328 slave + display ?
