The LiquidCrystal library exclusively uses software time delays and those delays are geared to the Hitachi specifications. To calculate the value of the series resistor, look up the maximum backlight current and the typical backlight voltage drop from the data sheet. If you happen to have one that does not include a resistor, you'll need to add one between 5V and pin 15. Even if the 600 was supposed to be 60 it is still 50% longer than the Hitachi. of LCDs (including ones from Adafruit) the LCD includes a series resistor for the LED backlight. The New Haven device is specified at 600uS whereas the Hitachi is 40 uS. The Clear Screen instruction is only slightly longer than the Hitachi, the Return Home is actually shorter, but the real problem is with all the other instructions. I took a look at your data sheet and it appears to be HD44780 compatible EXCEPT for the instruction execution times. LCD-3.3V-20x4 Datasheet Rev 1.0 20x4 Character LCD Datasheet Overview This is a large 20x4 character LCD module with selectable interface modes(I2C, UART, SPI). This is a symptom of an LCD module that is improperly initialized. Sometimes when I plug in the Arduino nothing shows up on the screen and other times garbage!
