FYI, I'm finding this, https://www.nxp.com/docs/en/user-guide/JN-UG-3115.pdf, quite a useful reference. For example see chapter 18 on an example of sychronising time by querying an attribute.

NOTE: I highly recommend AGAINST trying to fit the AMOLED version into the existing T-Display cases.

I just bought one, got it working great with a sketch from Volos https://www.youtube.com/c/VolosProjects, and installed it into one of the T-Display cases I have for my other regular T-Display devices.

It did seem to fit, so I didn't think much until powering it up... But now display only had a thin line on one end (by the buttons). OH NO!!

I took it out of the case and realized that because the acrylic covers the buttons there was way too much pressure on everything. And It somehow broke something in the screen or connector, as now it is simply dead, no image, no line, nada...

The ESP32 still works and I can tell it is running the sketch as one of the buttons toggles the green LED (which still works). But as the other adjusts the brightness (which of course being AMOLED is not a separate backlight), thus since the screen is dead that button does nada.

I contacted support about a replacement screen or something, but have been just getting runaround as no one seems to understand English well enough... They grab one descriptive comment and run with it as if it was the whole issue. 😞

So I am out about $45 CAD after a wopping one hour of use (including programming) and reluctant to purchase anything more from Lilygo due really questionable support options. Oh well... I will just stick with the regular T-Displays that I have I guess.

OK, can now confirm that an ESP32-C3 project built using the Espressif esp-idf framework can be uploaded to the T-ZigBee board. You will need to use the latest esptool (now a PyPi package) to ensure that the chip can be set to esp32c3.

@brekel Folks have cracked the LilyGO T-Display S3 display inserting into a plastic breadboard...ouch!

@behn4m Does this folder have what you need?

@patofoto Well, it took months and months but finally some guys over on the GitHub for ESP-Arduino finally found it!
https://github.com/espressif/arduino-esp32/issues/8324#issuecomment-1725784617
The helper util file in the onewire lib had an outdated notion that there could not possibly be pins greater that 33.
I edited mine and now it works!
Wow, what a ride!

@teastain2 OK, so I made this as a starter for you, but I cannot do the entire project!
Give me your email address and I will send you the program.

@kaly__ I tried this yesterday to pretty good results using an IPEX1 connector and a small antenna, no board modifications. Went from no connection to ~-75dB in my downstairs workshop.

@djmason merci pour ta réponse mais je pense que je dois les flasher en uart j ai essayer de changer d ecran avec un autre mais rien

@teastain2 Thanks for the hint !
This is exactly what I was looking for and worked perfectly.

@pbatch You can use an external 5V source and bring it in through the USB port.
Alternately connect it to the battery charging port (if there is no battery connected to it.)

@mikemcg I don't have a T-RGB to use, but I'll try to help.
But, most LilyGO boards' hardest to compile sketch is the factory.ino!
I can compile the GFX.ino for the T-RGB with no problems.
You might try a simple generic Serial.print test program to debug your rig.

//words preceded by "//"" are comments and are not executed bool ticktock; //declare ticktock as a boolean flag void setup() { //runs once on start up Serial.begin (115200); //open the serial port for USB cable } void loop() { //runs in circles! ticktock = !ticktock; //every pass through reverse the flag if (ticktock) { //test current value of the ticktock flag Serial.println("tick"); } else { //prints one or the other to the USB port Serial.println("tock"); } delay (1000); //wait for a second and run again! }

I am using:
-(MacOS, M1)
-Arduino IDE 2.2.1 , but 1.8.19 is fine but you must update all libraries
-ESP 2.0.11 (Board definition)
-I used Github to down load (clone) the complete set of files.
You really should copy all of the files (from the downloaded repository) folder marked Lib into your 'libraries' folder, overwriting and replacing the originals, but don't do a Arduino library update after that! LilyGO boards are very fussy about using THEIR versions of some standard libraries, not good form, tho'.
-All my libraries are current, except the aforementioned LilyGO supplied set.

-and the comm setup is:

"ESP32S3 Dev Module"
Upload Speed: "921600"
USB Mode: "Hardware CDC and JAG"
USB CDC On Boot: "Enabled"
USB Firmware MSC On Boot: "Disabled"
USB DFU On Boot: "Disabled"
Upload Mode: "UARTO / Hardware CDC"
CPU Frequency: "240MHz (WiFi)"
Flash Mode: "QIO 80MHz"
Flash Size: "16MB (128Mb)"
Partition Scheme: "Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS)"
Core Debug Level: "F' PSRAM: "OPI PSRAM"
Arduino Runs On: "Core 1"
Events Run On: "Core 1"

Hope that helps -Terry
