Customer:
I installed your library for the I2C LCD adapter and connected it to your 20×4 LCD, but only the first two rows work.
How do I enable all 4 rows?
Instalirao sam Vas library za I2C LCD adapter i spojio ga na Vas 20×4 LCD, ali mi rade samo prva dva reda.
Kako upogoniti sva 4 reda?
Hvala !

Just to be sure, can you confirm this is the library in question: GitHub - SolderedElectronics/Soldered-LCD-Library · GitHub
And you’re using the library with the I2C LCD adapter and 20x4 display.
Have you tried uploading the Hello World 20x4 example? Maybe in the LCD declaration you didn’t set it to 4 rows: Soldered-LCD-Library/examples/Hello_World_20x4/Hello_World_20x4.ino at 481a92e907361ac8e543360a94a648f6689c0b3c · SolderedElectronics/Soldered-LCD-Library · GitHub
samo da budem siguran, možeš li mi potvrditi, ovo je library u pitanju: GitHub - SolderedElectronics/Soldered-LCD-Library · GitHub
I koristiš library s I2C LCD adapterom i 20x4 displayom:

Jesi li probao uploadati baš example Hello World 20x4? Možda u deklaraciji LCD-a nisi stavio da je 4 reda: Soldered-LCD-Library/examples/Hello_World_20x4/Hello_World_20x4.ino at 481a92e907361ac8e543360a94a648f6689c0b3c · SolderedElectronics/Soldered-LCD-Library · GitHub

I found another library on your site: Soldered-16x2-LCD-Arduino-Library-main.zip
Now I see there’s another library too.
But now I see I have a new problem. I solve one, another appears.
Until now I used GitHub - forntoh/LcdMenu: Display navigable menu items on your LCD display 📟 with Arduino · GitHub to create menus, and I tested that on a different I2C LCD adapter that has a different chip from yours, and everything worked fine.
Now that I’ve switched to your I2C LCD adapter, the program won’t compile.
Users/tlevakov/Documents/Arduino/libraries/LcdMenu/src/LcdMenu.h:29:31:
fatal error: LiquidCrystal_I2C.h: No such file or directory
That LcdMenu appears to be tied exclusively to that library.
Do you have another library for menus or some other suggestion?
Hvala na odgovoru.
Na Vasoj stranici sam nasao ovaj library
Soldered-16x2-LCD-Arduino-Library-main.zip
Sad vidim da ima jos jedan library, hvala 
No, sad vidim da imam novi problem, jedan rijesim, drugi se pojavi.
Do sada sam koristio GitHub - forntoh/LcdMenu: Display navigable menu items on your LCD display 📟 with Arduino · GitHub za izradu
menija, i to sam probavao na jednom “I2C LCD adapteru” koji ima drukciji
chip od ovog Vaseg, i sve je radilo OK.
Sad kako sam “presao” na I2C LCD adapter od Vas, program se ne zeli
kompajlirati.
Users/tlevakov/Documents/Arduino/libraries/LcdMenu/src/LcdMenu.h:29:31:
fatal error: LiquidCrystal_I2C.h: No such file or directory
Taj LcdMenu je izgleda vezan iskljucivo uz taj library.
Da li imate nekakav drugi library za menije ili nekakkav drugi savjet.
Hvala !
Soldered Support:
Good that it’s working. I’ve sent a request to have the old library removed to avoid confusion. That LCD menu library would need to be modified to work with our library. Unfortunately we can’t do that through support because it’s third-party software, but I’m sure it shouldn’t be too challenging.
There’s no other menu library. Also, I’m sure you can implement a menu without a library if it’s simple enough.
super što radi, poslao sam zahtjev da se stari library makne kako ne bi bilo zabune. Taj library za LCD menije bi trebalo modificirati kako bi radio s našim library-em. Ovo na žalost ne možemo napraviti preko supporta jer je riječ o softveru treće strane, ali siguran sam da ne bi trebalo biti pre izazovno :).
Drugi library za menije ne postoji, također, siguran sam kako možeš implementirati meni i bez library-a, ako je dovoljno jednostavan.
Customer:
I’ll try to adapt LCDMenu.
But I see there are several LiquidCrystal_I2C libraries.
And I see in your Soldered LCD library you also use some LiquidCrystal_I2C library.
Which exact one did you use to develop your breakout?
The second one is used by LCDMenu.
Hvala na smjernicama, pokusat cu prilagoditi LCDMenu. No, vidim da ima nekoliko Liquidcrystal_I2C library-a. A vidim u Soldered lib-u za LCD koristite isto neki Liquidcrystal_I2C lib. Koji tocno ste koristili za razvoj vaseg breakout-a? GitHub - mathertel/LiquidCrystal_PCF8574: A library for driving LiquidCrystal displays (LCD) by using the I2C bus and an PCF8574 I2C adapter. · GitHub GitHub - johnrickman/LiquidCrystal_I2C: LiquidCrystal Arduino library for the DFRobot I2C LCD displays · GitHub Ovaj drugi koristi LCDMenu.

Glad to hear it, that was quick to resolve
We used LiquidCrystal_I2C (the second one you linked), just an adapted version for our I2C LCD breakout.
drago mi je čuti, brzo se riješilo
Mi smo koristili LiquidCrystal_I2C (drugi koji si linkao) samo prilagođenu verziju za naš I2C LCD breakout.
