When i connect lcd 1602 to arduino to display lcd ,no problem seems to come up. but when i connect lcd with atmega32 only , the display is not stable , sometimes characters on lcd appeared weird , other problem could be as blurry characters , some special characters display instead of what intended to be shown .
I dont know exact why the ldc behaves like such , i tried google and still had no clue . I been suffered for a while , and desperately need help .
Your topic has been moved. Please do not post in "Uncategorized"; see the sticky topics in Uncategorized - Arduino Forum.
Please provide a complete wiring diagram or schematic of your setup. How is your setup being powered? Please share your code (don't forget the code tags).
Post your schematic, and some bright, clear photos showing how everything is wired. Describe how everything is powered.
I think there is a loose connection. Also check if you've attached the resistor/variable POT properly with the V0 pin of the LCD.
