@eliott I'm not sure about this product.
Are you asking for the exact firmware that shipped with your watch when new?
Here is a link to example sketches at the LilyGO repository:
https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/tree/master/examples
To be sure, you may raise and "Issue" on this site, which may take a long time.
I have found that a nice inquiry at their office address works:
sales@lilygo.cc
Also LilyGO suggest this GitHub repository:
https://github.com/sharandac/My-TTGO-Watch
Hope this helps!

Yes. ESP32 supports CAN and these are featured S3 boards.

RE: Unable to make T-Display S3 work with LiPo battery
Sounds like the ol' GPIO 15 must be turned on HIGH issue.
This enables the display power and the circuit that uses and re-charges the battery.
I made a support repository for new users here:
https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples
My examples are the simplest possible sketches that use the display, TFT_eSPI and Serial.print functions, as a sort of tutorial.
Hope this helps -TerryIf you are not running one of my sketches, you should add:
#define PIN_POWER_ON 15 // LCD and battery Power Enable
#define PIN_LCD_BL 38 // BackLight enable pin (see Dimming.txt)just before the setup and then in setup add:
pinMode(PIN_POWER_ON, OUTPUT); //triggers the LCD backlight
pinMode(PIN_LCD_BL, OUTPUT); // BackLight enable pindigitalWrite(PIN_POWER_ON, HIGH);
digitalWrite(PIN_LCD_BL, HIGH); -
RE: T-Beam SUPREME - Charging battery when off
@luffe LilyGO products...generally yes, they charge all the time while plugged in to USB.
You should conduct a simple test with your actual unit, as the documentation is very sparse.
(I could not find a schematic for your board)

RE: How to operate T-Display-S3 Touch out of the box
@danardi It is indeed annoying and it gave me trouble, but I figured out that you can edit the pinconfig.h that appears in the Arduino IDE off to the right with your own SSID and Password and avoid the ESPTouch nonsense. (this 'ESP touch" has nothing to do with the optional touch screen, BTW)
If you are new to LilyGO T-Display S3 I made a support GitHub repository here:

RE: Boot-Problem: LilyGO TTGO-S3 Touch
HotHead here!
So, the HotHead sketch works on battery, yes?
Could you post your temperature code here so I could run it on my LilyGO T-Display S3 ?

RE: How to flash T-01C3
@teastain2
(you need to cross over TX to RX so that the TTl TX is the LilyGO RX !) -
RE: JST-GH connector on T-Camera S3 ?
@jip The recommended battery is this:
Panasonic Lithium Ion 18650 3.7V, 3400Mah
You can put 5V into the two prong battery plug and the regulator will bring it down to 3.3.
The unit will still work, somewhat @ 3v. -
RE: Is T-watch 2020 V3 water resistant?
@ivan Hi Ivan, this site is a volunteer user community site and anything I say is simply "advice".
LilyGO make no claim of waterproof, but it seems well sealed.
I think accidental splashing such as washing hands would be OK.
Otherwise I would "Damp-Cloth" it as you say!

RE: T-Display S3 AMOLED: monitoring works but can't upload
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 delay(500); } 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! }
Also try Arduino IDE if all else fails.

RE: T-Display S3 AMOLED: monitoring works but can't upload
@mshthn Would it help if I gave you a generic serial test Arduino IDE sketch
This way it does not rely on any libraries.
Once I get this running, I increase the complexity of other more complicated sketches to see what breaks it. -
RE: LilyGo-T-SIM7080G recognized as wifiduino32s3
@kokox3 This is a silly feature of Arduino IDE where it tries to guess your board and gets it wrong. Just ignore it and tell it that you have a ESP32S3 Dev Module!
I guess that you are using Arduino IDE ?
I can help with the Arduino side, but am not familiar with SIM7080 stuff! -
RE: T-Display S3 AMOLED: monitoring works but can't upload
@mshthn The bootloader is indestructible and buried deep in ROM!
Can you show the actual program that caused this?
You say you can still see serial monitor?
Perhaps the sketch BEFORE this last one is hung up?

RE: Lilygo T4-S3 is not working
@ohiojoe I am noticing the two button thing is required now, I still searching to find out why!
You can set up a 'New Sketch' and put it where you want!

RE: t-deck wont run on battery
@dawack In the GitHub examples you can see that the Arduino IDE sketches start with:
#define BOARD_POWERON 10 //then in setup... pinMode(BOARD_POWERON, OUTPUT); digitalWrite(BOARD_POWERON, HIGH);
Could you check and see if your program has this?
-
RE: t-deck wont run on battery
@dawack Some LilyGO products need the Power Enable output to be 'ON' to run on battery.
With your board it is GPIO 10.
Could you try that? -
RE: Lilygo T4-S3 is not working
@ohiojoe Were you able to get the test code that I posted to run?
