Adafruit 1.8" TFT display ST7735 white screen

Other Hardware Displays

So I just got the Adafruit 1.8" TFT display and i wired it up to my OSEPP UNO rR3 Plus and all im getting is a white screen, ive been dozens of forums and websites trying different things but nothing seems to be working, I must have rewired the thing a million times but it still wont work. I'm still a little green to arduino so I'm thinking maybe its my programming abilities but the I don't know of the arduino examples could be that wrong.

I do know that the screen is getting some kind of signal because the data wires/pins can make a LED blink and flicker so if anyone has experience with this or has any ideas I'd love the assist thanks

It is always wise to post a link to the actual display that you have e.g.
1.8" Color TFT LCD display with MicroSD Card Breakout - ST7735R from Adafruit.
or perhaps 1.8" SPI TFT display, 160x128 18-bit color - ST7735R driver from Adafruit.

There are many Red boards on Ebay that only cost $4 or so
1.8" Serial 128X160 SPI TFT LCD Module Display + PCB Adapter + SD Socket

The cheap Ebay modules and the bare Adaruit screen must have 3.3V logic. Do not believe the Ebay vendors.

As a general rule, Adafruit take great care to make their "complete" modules 5V compatible.

Read the current thread from bodmer.

One of the few reasons to purchase from Adafruit is their Support/Customer Service; another is they (almost) always have test sketches for their products. Run the test sketch. Take Notes. Ask Tech Support on Adafruit if you are not successful.

Well, Adafruit says that you can use 5V logic. I would believe them.

Double check your wiring. Run the Adafruit example code.
Personally, I am always happier with the RESET pin connected to GPIO.

Ask again if you still have a problem.

Adafruit have very good tutorials on their website, if you follow this one (which is specific to that display) carefully you should get the display working.
