Hi Sara,
Thanks for your reply. Even i found the library for the LCD3310 last update to be 6 years ago.
Anyway, I will try to explore how I could make it work.
Thank you very much.

Cheers!
Joel

Hi Joel.
I never tried this display with the ESP32. I also haven’t experimented with that ESP32 board.
The display uses SPI communication. So, I guess that you should set manually in the code the SPI pins you want to use.
I’m not sure if the library in this tutorial is compatible with the ESP32.
This tutorial is very old. It may be outdated.

I have instead an Olimex MOD-LCD3310 with UEXT connector and my development board is ESP32-PoE-ISO. I understand that some of the UEXT pins are shared like GPIO4 and U1TXD; GPIO16 and I2C-SCL and so on. Is there anything I need to set in the code so that these shared pins in UEXT function as intended for the LCD-3310?
Thank you in advance.

PS.
I am enrolled in some of your courses (6). I am currently on “Build Web Servers on ESP32 and ESP8266” but I just whizzed through the pdf guide and so progress is not tracked. I am a dot net developer C# and have good electronics background but new to this “Arduino” thing as a hobby, and just starting my personal IOT projects.

Hi.
Make sure you always check the pinout of the ESP32 board before starting any project: https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

In reply to David Connolly. I had a lot of trouble with this module until I realised one of the pins I was using on my esp32 (pin 34, I think) was an input only pin.

Works great!
look in header:

// All the pins can be changed from the default values…
PCD8544(uint8_t sclk = 3, /* clock (display pin 2) */
uint8_t sdin = 4, /* data-in (display pin 3) */
uint8_t dc = 5, /* data select (display pin 4) */
uint8_t reset = 6, /* reset (display pin 8) */
uint8_t sce = 7); /* enable (display pin 5) */

Parabéns Rui pelas explicações.

There are two variants of the 5110 LCD. One uses the pins you describe under Pinout above. The other uses the pin configurations in your Hello World demo. They are different. The code makes no provision for the back light (Pin 7 above). And… line 58 sets the glypy, but the compiler shows a type incompatibility. Bottom line, I could not get this to work or show any activity on the screen.

In reply to koliber31. As Rui points out, there is, unfortunately, no standardized pinout for various 5110 modules being sold on eBay and elsewhere. Mostly the modules do have the pins labeled, though.

In reply to koliber31. I would double check your LCD pinout from the store that you bought
