For arduino operation, performance is not as important as speed and ease of coding and it allows users to mix and match code to get it working but you should be aware that underneath all the magic there can be a lot going on and you could re-write it or re-wire the hardware for better performance. Returns cursor to home position. Larger custom sizes are made with 32, 40 and 80 characters and with 1, 2, 4 or 8 lines. Sanchez, Julio; Canton, Maria P. State3 may occur, for example, if a prior control was aborted after sending only the first 4 bits of a command while the LCD was in 4-bit mode.
