This is what I did.

Fed all grounds into a block like this...

Soldered all pins together and taped and sealed with electrical tape.

Eight grounds from the OLED go into this and one ground from this block is fed to the GND on the TTGO.

I built this at lunchtime using a Circuit Board sourced from the spares of Gojira54. Its a wonderful little thing. Thanks for making this project and open sourcing it. Thanks also to whoever designed the circuit board it makes it much more easy to build. Its just a case of soldering some pin headers.

I couldnt get the tiny tiny resistor off the OLED for 4 SPI mode so I just cut R5 using snips and solder bridged the correct jumper on the OLED

That's me, you're welcome. That was born of pure self-interest, but with "open" in mind as in the next post and upcoming project...but psssssst! Don't let anyone know publicly! :lol:

You can do this as well.

Updates
  • USB-Version
    Autodetection of Board Type in Arduino Sketch when using the Arduino IDE.
    No need to set the Board manually in the Program Code.
    Functionality tested with Arduino IDE 1.8.13, ESP32 Package 1.0.6, ESP8266 Package 3.0.0,
    TTGO-T8, Wemos Lolin32 and NodeMCU 8266.
  • New (untested) PCB by RealLarry for ESP32 Wemos Lolin32 v1.0.0/ESP32 Lolin32 (with Solder-Bridges).
    Use the solder bridges on TOP for Wemos Lolin32 v1.0.0 .
    Use the solder bridges on BOT for Lolin32.
  • Pictures: I think we have now a picture for all actual Computer & Console Cores.
  • Removed Stuff related to ESP32 Devkitc v4 (doesn't work correctly).

Got my first Cardware Donation from Bracknell/UK :)

I had problems to get an Devkitc V4 from AZDelivery working.
Serial was working alone, Display was working alone
but together i can‘t get it working.

Do you have a working one?
If yes, drop some pictures here if possible and let me know which Pins you use for the Display and which board you chose in the Arduino IDE.

As Venice already stated, it doesn't work at the moment. I initiated the combo of a Devkitc v4 (AZDelivery) and display and it has worked. After designing and receiving a suitable PCB it turns out that the Devkitc doesn't want to play anymore. Venice bought another one for himself, tested and totally rewired the device, but nothing. Not comprehensible so far.

You can use a Wemos Lolin32 instead. Wiring diagram is on it's way:

I just wanted to say thank you for a really amazing project. I got all my parts in the post this morning, soldered it up and got it running in less than an hour. Really impressive stuff. I particularly like the transitions between graphics, it adds a little bit of shine to it.

For the Arduino, I have two TTGO boards, which I can use with Dupont wires and a breadboard. The Devkitc is available with pins already on it and has a terminal breakout board available though, which enables more permanent wiring. I just bought two of those and the breakouts.

I'm a little frustrated to see the Devkitc isn't working after all.

I understand.
We can try your Devkitc Board when your Display arrive.
If it‘s not working we can use your TTGO‘s as well.

Where are you located?
Maybe there is someone around you who can help.

It's a TTGO ESP32, way over-powered for this job (I'm sure it could be done with an ESP8266, but it's a nice form factor and it was a decent price on Ali).

AliExpress ? Have you got a link to the one you bought please ?

I am hoping to place an order today for esp, screen, some other port extensions and a case today, probably all from Ali. I'm in the UK.

I am sorry to slow you down a bit but this ESP Breakout is for the "Devkitc V4" ESP32 which I can't get to work with the tty2oled Arduino Program and my Controller. We must wait until "Mellified" get all his parts and we can start to test or I get new hardware for testing.

Here're links to what I ordered. I'm still waiting on the screens so I haven't done anything other than mount the boards onto the terminal breakout.
