Thank you sir !! I've been banging my head against a wall with all the garbage from piecing info together. This gave me the dangling carrot of hope I needed to keep tinkering with it :)
Thanks for this tutorial. I got it working on my T-Display. I went back and edited your code so that, when a score equal to or greater than 100 is achieved, pin 2 on the board will go HIGH. Maybe I'll have that trigger a dispenser so players can get a reward for a game well played.
Hey man, I'm going to have to wait a bit longer to get the new board you covered in another video so I was looking at this video list of the older board and I find them very interesting and useful to get me started with this board as well so I'm gonna buy this board also and use your link to make sure you'll get the commission. It's the least I can do to support you doing this great work spreading the information. Have a great day.
Great video - these instructions still continue to work even on a Mac running Arduino IDE 2.3.2. Just be sure Tools> Upload Speed is set to 115200 or you'll get a "Unable to verify flash chip connection" error.
Thanks for very nice explanation and making a great video. May I ask if you could let me know how to connect NodeMCU ESP8266 V3 with 3.5 inch TFT touchless display having ILI9488 driver? I want to use TFT_eSPI library for it. I tried many configurations but was unsuccessful. Can you please let me know the wire connections and if any changes required in the TFT_eSPI codes? Thank you very much for your help in advance.
Thank you for making the tutorial on how to change the TFT_eSPI code, works great. I was wondering on the .h files are those converted jpeg files for example the background of the game

It is posible, but it is tricky becouse spi but is already used by screen, you will need to use vspi for screen and hspi for device forexample
congratulations on your vlog. I have a problem, I can't get the ttgo card to be detected by my Windows 10. Cás you hep me
problem solved. damaged usb cable. :-)
I am getting this error while using my ttgo why is that happening could you please help me about it?

did you select correct board in board manager, you need to select TTGO Lora32 OLED
@@VolosProjects yes i did but still same :( I am working with a sensor and I want to see some datas in the serial monitor but its empty there. Is it possible to see the datas on the serial monitor while using this board?
In device manager it show exclamtion mark in usb
Hello, I can't get other ports on my computer I need help!
I get the following errors when I try to upload it:

I googled this and apparently this one .h file contains the UTF-8 Byte Oder Marker. I was able to resolve the problem by putting the cursor at the start of the firs line and pressing backspace to delete the illegal characters. The other .h files seem to be fine. I'm using Windows 10. I downloaded them as a zip file from Github as you did in the video.
Try to delete empty lines in .h file, this is error that came with new versions of IDE
@@VolosProjects Interesting. It's curious that only the enemies.h file is affected. As I said, I got it working by (presumably) deleting the invisible characters at the start. Any idea why only enemies.h was affected?
@@VolosProjects same thing happened to me, and I can confirm that deleting all the blank spaces in the enemy.h file worked and it compiled correctly after that. Thank you to Volos and Ytubeleo
Problem:
Connecting........_____....._____....._____....._____....._____....._____....._____
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
Solution:
Before pressing Upload, hold down EN button (the button to the left of the USB) and only
release once "Connecting..." shows up
Can you teach me how you do this I can't figure it out
Hi When i Compile it i get TFT_BL was not declared in this scope
Check your libraries, are they updated
I tried it so much bt there a prob ,usb didnt recognise esp means nothing show any com port
you will need to install driver, go on liliy go site, on product page of t-display and fallow instructions there
Not sure why but in 2021 this is not working with these libraries and arduino 1.8 Spent a lot of time trying to get it to compile.
What eror your are getting?
Thanks kindly for the reply. I actually managed to just get it to compile by removing frames=4 line. The wifi weather station tho. I spent a good 2h trying to get that one to compile. Issues with wifi library and type casting issues.
So stray error
how flash original firmware ?
Code doesn't compile, says TFT_BL was not declared!
So it's a problem with your SW or settings. You probably don't have the right libraries.
my TTgo screen stay black and the blue led flash

These Boards are a pain in the ass. I cant even find the driver because i have no clue which version i have.
NO me aparece el puerto/I do not see the port
"TFT_BL' wass not declared in this scope" anyone have a solution
update your tft_espi library.

I had this same problem on a MacBook Air M1..I used sublime text and saved the enemy.h file with encoding Western (Windows 1252) and that fixed it for me
Просто удалил строку и все отлично 👌🏻
@@VolosProjects I had the same problem. I simply deleted the line: int frames=4. Problem solved 🙂

Someone else posted a fix, but hopefully another post will help someone find the fix.
The Enemy.h file is saved as a UTF-8 BOM file, and needs to just be UTF-8.
Download Notepad++ and open the file. Go to the top and look for encoding and you should be able to figure it out from there. It compiles fine now!
@patufetselaer3651 was the person I saw post the fix.
thank you 👍
I cannot get these TTGO boards to connect to my mac: Has anyone had this issue? followed the istructions to the letter.

Hi,
Love your vlogs.
This one gives me a compilation error though.

Eventually, after scrubbing the system of any Arduino related files, doing a clean installation of IDE 2.3.2, keeping all defaults, and following your instructions to the letter, didn't get rid of the problem. Replacing the esp32 v 3.0.2 boards package (by espressif) with version 2.0.17 in the boards manager solved that problem (thanks espressif?). This solved most other problems I got from compiling for ESP boards as well. AlienAttack now happily compiles, uploads and runs like a charm.
P.S. Nobody ever told us computing was ging to be a breeze...
amazing video! thanks!
Thanks for your tutorial...
