There is some strange thing about the interrupt of keypad module. Some times too slow to send the key release interrupt, using same click on keypad，but sometimes keypad interrupt comes within 100ms，sometime 1s. The problem is caused by clock source, but the keypad controller of am572x has no other clock source, so the problem still no resolved. We often purchase the Keypad Module not realising that this is a discontinued product.
I’ve replaced the keypad module in every single one of them. In fact, I did one of them twice. And two or three more of them have totally borked lamp power buttons. The problem is just that the membrane design becomes a self-perpetuating failure of sorts. As the button wears out, you need to push it harder to get a response. At the same time, pushing it harder makes it wear out significantly faster. Replacement requires disassembly of the entire ELCA box too, so that’s not fun either.
Most LCDs today also use a source of light coming from the rear of the display (backlight), such as a fluorescent light, to make the liquid crystal appear darker against the screen when in its cloudy phase. LCD makers also use sheets of polarizer material to enhance this effect.
