Is it possible to have more than 8 characters in the LCD display?

Question

Arduino

There is a 1602a LCD display with i2c and an arduino uno compatible board. The LiquidCrystal lib is used to control the LCD, but in this lib you can create no more than 8 custom characters ("for compatibility"). Is it possible to do more with this LCD display?

Answer 1

Custom characters are loaded into the LCD controller's own memory, and there is only room for 8 characters. Maybe there are compatible displays that allow more than 8 characters, I don't know.
But no one bothers to set as many custom symbols as you want and load them into the indicator at the right time. You can simply display no more than 8 different ones at the same time.
