LCD question
Posted: Tue Dec 07, 2010 2:08 pm
HI everyone,
I just wonder that how I know LCD (liquid crystal display) is faulty?? Do I need to download some code in the microController to test it out or I just need to put the Voltage for the LCD?If I apply 5V to LCD,what should I expect to see on the screen of the LCD?
thanks
