Hi i had a Character lcd with I2C.(I don’t want buy graphic lcd or tft) but theres a problem when i use more than 7 characters its replaces old one. I don’t want this. But i learned lcd’s have a rom for loading existing characters.
Now i want replace factory loaded characters how i can do.
Note i was not going to replace english characters i just going to edit japan characters to custom symbols.
How i can do that.
