Hello, in the last time i have made my first steps with arduino. It have had no problems to interface dallas temperature sensors , DS1307 RTC and LED-Displays with SAA1064.
Now i have try 16 * 2 LCD-Displays, i think 6 data-wires and Voltage is no problem. But the displays only show the first line (the second is dark) as 16 Blocks (all pixel). I have try 4 different displays (datasheets say HD44780 compatible) and 2 librarys ( the normal including in arduino) and the 4bit library. All the same. All pages in the internet show the same wiring and the same librarys. i am working wis arduino vers 17.
has anybody some suggestions, i am very frustrated.
kind regards from germany Gerd
