- Raspberry Pi Color Display ST7735 How to use tutorial with Circuit Python
In this video I am going to show you how to connect a 1.8” color TFT display that uses the ST7735 driver to your Raspberry Pi Pico board and use it with CircuitPython. I will also share with you 2 simple programs I developed using this display to help you get started.
If you are long time viewer of this channel you know that I like this display a lot and I have used it in many of my Arduino projects. It is inexpensive and easy to use. At the time of this recording, it costs around 6$. Add another $6 for the Raspberry Pi Pico board and with just $12 you have a pretty capable development platform.

Thank you I made your clock, but cant believe it was 7 years ago that I made it, so thanks for that, and this video. Bob in the UK.
cool man
I hope you took away lots from this video. Let me know below!

Found a cheap display like that so I check out some videos. I plan to use it for a clock, temperature or something with a Pico eventually running all the time and the RPi is too power hungry (Amps).
hey ty for this great tutorial. Is possible to do this only on a rp2040 zero. its smaller version with less pins. ty i was trying to find something but i dont see anyone that do this...
Nice tutorial. Thanks. Issue with simple test code. Was getting attribute error ".show(x) removed. Use.root_group = x". Apparently 'show' no longer used. Solved by editing line 25 to ... display.root_group = splash
I’m trying to run the slideshow program. Everything looks good at first but when I run the code through Thonny my screen just stays white and never shows an imagine. And the only error it says is on the last line sleep(2). But I think that’s because I’m shutting down the program but maybe I’m wrong. Any idea what the problem could be?

Thanks for this video. What is the library to use to display lines/rectangles on this display?
You need the adafruit_display_shapes library from the library bundle.

How to setup circuit python and pico on VSCode ?
Дисплей 3.3V включаете на 5V?
hello i am struggling with having a white screen!! i got mine with pre-soldered headers so i would assume that would mean that is should all be working but no matter what i try its always a white screen any ideas?? thanks so much :)
I'm having a similar issue. I got a slightly different screen, it has a few extra pins, but they are labeled nicely. I was able to find the exact same pins as described in this video, wired the same, and pasted the sample code. It "runs" without complaining, but my screen just stays white. I'm not sure. Did you have any luck?
OK quick update, my screen had a different input called SCL...I ended up connecting the clock wire from the PI to the SCL pin on the screen, and it worked!
You must do one for me please.
can we play video file?
more Raspberry Pi Pico projects please
i bought one but there seems to be no good projects for it ,most of the existing projects can be done with arduino
no one is using the full potential of the pico
Sure I can build more project with this board. With $6 this is one of best boards out there.
@@Educ8s Very interesting. Looking forward to more builds.
You can program Pico just as regular Uno.
@@Educ8s At Pimoroni, 10x RP2040 costs £9. Nice for custom projects.
@@dekipet Sure you can do that, but with CircuitPython, development is much faster.
Does the image stay on the display if we plug the pico from an external power source or do we need to have it hooked to the computer for this to work?
If you save the code as code.py this script will run everytime you powerup the board. So, it doesn't matter if it is powered from a computer or a power bank or a power brick.
@@Educ8s thank you!
5:18, that looks so slow though, like 3 fps
А если дисплей после загрузки кода просто серый, то есть просто работает очень слабо подсветка, что это значит?
were do i get one
did you check the video description?
trying gauges ... ImportError: for adafruit_display_shapes
Have you copied the adafruit_display_shapes library in libs folder on the Pico?
@@Educ8s thanks. Not seen on the video, missed to add :D
I'm having an issue, when I try to load the first example project into the raspberry pi pico, the screen just stays white. I added some code that turns on an LED and that worked so I am a bit confused.
Edit: To anyone else having this issue, and is sure that their wiring is correct, make sure you push the pins of the Raspberry Pi Pico and the screen all the way down and you copied the sample code correctly, that's how I fixed it.
Please check your connections again carefully. That's the most common reason for a white screen.
@@Educ8s Thanks for the reply! I have one question, do the distances from the wires to the raspberry pi matter? This is one of my first times using a breadboard so I'm not very good with it.
@@GordonFeeshman No, the distance does not matter.
@@Educ8s Ah, that makes things easier. I will check my wiring, thanks for the advice!
@@Educ8s So I checked my wiring and it seems fine... Do I have to edit the sample code? (I am using the sample text program)
hello, i like ur testing videos. may i have a collaboration with you for promotion? tks!
