i had a idea to build some kind of multi-use tool for troubleshooting in electronic and electric installations . started the project,, the heart of tool is esp32 . equipped with rotary encoder for menu selection and 128 x 160 tft. for now i managed to implement voltmeter for dc max 30, continuity test with buzzer, flashlight, and lux meter . im stuck on network cable tester. was thinking to make diode voltage droper on far end between all eight wires and than to send high signal trough first wire and trough remaining wires on esp32 (ADC) read voltages.
but i dont know how to setup code. Need to put read values into string and than sort string to see if wires are in correct order, or missing some of them, or crossover cable, or shorted .....
any kind of help is appreciated.

You almost certainly don't need to do any such thing. Why use strings ?
Have you searched the forum for "network cable tester" ?
searched and didnt find suitable solution to get results on tft like this:

Testing the cable and formatting the data on the display are 2 different things
Concentrate of getting the data and output it to the Serial monitor in the first instance then move on to displaying it on the TFT
