Please Help With Simple Code/Wiring.

Other Hardware Displays

Hi Folks,

I Have mastered everything arduino except LCD :neutral_face: . The only LCD's i can get going are the
number displays. I Want to print text, and i own almost 30 LCD/TFT's that I've brought off of
eBay for various prices and of various sizes over a couple of months. So i thought I'd start it simple,
if one of you pro dudes can do the following for me i would be forever in debt. In the photo i have
uploaded, is the first LCD that i got, so i guess it must be the most simple. All i want is for you to
tell me which wires go where, and some simple sample HELLO WORLD code.

With much respect.

Google for Arduino LCD 1602 and you’ll find many examples. Hint: with an I2C backpack, it is much easier to wire up.

Thanks Man,

I Have this problem, i have managed to get the screen light up on some of my displays, but no text.

Here is a tiny TFT I Purchased called TE667.

I Downloaded this library which is appropriate for it. GitHub - greiman/SSD1306Ascii: Text only Arduino Library for SSD1306 OLED displays

But i don't understand the simple wiring, for instance, my TFT has four pins, "GND" which is obvious,
then VCC, which i assume is +voltage?(help). Then "SCL"and "SDA". In the code it often outlines CS
and DS as pins. Which ones are CS and DS? SCL or SDA?

Thanks so much for your helping me here.

Trent.

Try this 1602 tutorial.

Thank You,

I Have spent my day trying countless TFT codes, none work, i get a blank white screen,
sometimes it jitters if commands are being sent, otherwise it's useless. My TFT display is
labelled on the front 3552, on the back :

3.5" TFT LCD for arduino uno

It has the following pins :

LCD_RST
LCD_CS
LCD_RS
LCD_WR
LCD_RD

LCD_D2
LCD_D3
LCD_D4
LCD_D5
LCD_D6
LCD_D7

LCD_D0
LCD_D1
SD_SS
SD_DI
SD_DO
SD_SCK

GND
5V
3V3

Any help with how to get this ********** thing displaying text would
be met with as much gift as i can give. Thanks.

  1. Install/Update MCUFRIEND_kbv library via Library Manager.
  2. Plug your shield into your Arduino.
  3. Plug your USB cable into the Arduino.
  4. Run diagnose_TFT sketch. Copy-paste the Serial Terminal to your message.
  5. Run LCD_ID_readreg sketch
  6. Run graphictest_kbv sketch

Thanks heaps david. I Did try this library today, latest version, to no avail.

I Will do what you say tomorrrow. But first, what do you mean by shield.?.

Google "Arduino Shield"

The important thing is that every male pin should have a corredponding female socket.

You'll get some confusing answers because you have given different details in different posts.
In your first post, you referenced this picture. It is a LCD 1602 display (maybe with an I2C back pack)

Later, you appear to be talking about a te667 display:

Finally, you are talking about a display marked 3552

In the OP you talked about 30 different displays you have purchased so it appears you are doing a considerable amount of experimentation!
