LCD Nokia 5110, test if the data appears on the display

Using Arduino Displays
1

Hi.

I test LCD display Nokia 5110. I don't know which pins are connected. I can write code to test all of them, but it will long testing.

Can I test if the data appears on the display? And if yes, how?

This is an extremely common display. You should be able to find all the pinout information you need with just a little bit of searching.

If you think there is a magic program that will be able to work out which pins on the Arduino are connected to what pins on the 5110 display, you will have a very long wait for an answer ................

Yes you can. You test if the data appears on the display by looking at the display and seeing if the data is there. This is usually best done after correctly wiring the module and sending some data thereto in the correct manner. The correct wiring is usually accomplished by checking the designation of the pins on the back of the module. About the only variation is the backlight having a supply or ground pin, which doesn't affect the data, and indeed is usually redundant.

It imposibble read data from display?

When I try to send data to display, wait and read answer?

Display has 5 pins, Arduino Nano 13 Digital pins. Delay to 0,5sec and just lookin on display?

13^5 * 0,5 = 186646 sec

Apart from the above, which actually contains a strong message about what might be going on, your post is incoherent nonsense.
While there are minor differences in labelling and connection, every Nokia 5110 I know of has eight pins, and every Nokia 5110 library I know of expects you to use at least seven of them. It is probably time for you to fully identify the display, post the code, and show the wiring.
Note that it is not actually necessary to use a library for this display.

I have Arduino Nano and Nokia 5110 display.

This both things are connected on the printed circuit.

I cannot find out the wiring (which pins are connected).

How can I find out the right pins?

Some function to test data sending, I don't know.

Thanks for helps.

Your words are meaningless gibberish. If you want help then you need to make the effort to provide the requested information. Otherwise you're just wasting everyone's time.

Have you tried Google?

Do you read what I need?

I know how to wire it.

I have thing (ex FM radio) with Nano, speaker, some FM chip and this display. I cannot find out how the things were wired. But the things are wired. I need a function to check pins and find out which pins are connected to display. The real wiring I cannot see.
