You can see a LCD wired on a board above. based on the back of its board, it has 8 pin and its seventh pin and eighth pin is connected to VCC and GND. I search in internet for datasheet of this LCD. But I found nothing. Does any one know where I can find it? What kind of protocol does it use to communicate with MCUs?
And how I can monitor its pin to see the data transfers between it and a MCU? (I don't have scope or logic analyser. I want to monitor its pins by an Atmega32 and send the data to my computer's COM port. but I don't have any idea how!)
