      @papbo What is your current ESP32 version? Try upgrading?

      @eifel69
      I was able to see the clock lettering (Alivaba font) by opening up the ESPTouch app and passing my WiFi credentials while the FACTORY was loaded in my T-Display-S3.

      My favorite YouTuber Volos has a good video where he covers how to use custom fonts.
      https://youtu.be/R-qFKemDFyM

      This is part 3, so it’s also worth reviewing parts 1 and 2. Hope that helps.

      UPDATE: Just realized my clock is an hour off. Hope your results are better.

      @teastain fantastic link many thanks again, do you know anything about using DMA on the ESP32-S3?

      I want to try and improve the gfx performance of the Arduino_GFX library, and it looks like memory performance is quite the limiting factor (possibly due to the canvas buffers being allocated in ps_ram?).

      @tavdog I saw Mickey closed your issue in LilyGO T-Display S3 repository ?

      This is confusing because swap bytes is much like reversing a film negative in that it should change radically with swap bytes true or false.

      Did you checkout my LilyGO T-Display S3 repository ?

      [edit] I just did this test of your image on my LilyGO T-Display S3 !IMG_5776 2.JPG
      point is that blue came out blue and red is red!

      @teastain2 ... OMG ... I got it running ... and I am almost to embarrsed to tell the reason ... obviously the breadboard I was using for the T-Display was broken and did not have contact for pin 13 😞 Changing the breadboard solved the problem, Ethernet is now working correctly!

      @teastain2 Thank you Terry,

      I'll give the instructions a go and see if I make it to work the way I want.

      @patofoto No worries, I'm a retired engineer with spare time, looking for a challenge.
      Well, you did get a value from the Dallas while it was under ESPHome.
      I could not see anything in the YAML that configures the I2C port signal SDA to be a bi-directional serial comm link like onewire!
      There must be another config file when you select LilyGO T-Display S3 .
      I'm still poking around on it, intriguing.

      Here is my new Faster MicroPython Driver for the T-Display-S3. It's a work in progress and it is slightly different than my last driver, but it is faster.

      @whippe Interesting!
      hmmm...I am way out of my depth here.
      The PeakCan seems to be CAN to USB.
      Do you have an example sketch to base this on?
      The ESP32 connects to which end, the USB or CAN?
      Does the equipment offer automotive style OBDII communication?
      If you have the time, I'd like to know!

      @yakuzja There are two ways to get started quickly

      Use the Arduino IDE and install the ESP32 support package. Use the VSCODE PIO plug-in, this plug-in can automatically configure the environment for you, the compilation speed is relatively fast, and it also supports Arduino functions and libraries

      @metawops I have no idea what the factory sketch is supposed to do!
      Thats why I made my HotHead example, to debug and get it running.
      I studied the code and made the Hothead tempsensor and a FPS version (not included in the repository that I posted) to determine Frames Per Second.
      I also added the LCD backlight ON command to HotHead, after both displays "went dead". This revived them.
      The factory tft.ino included in the factory download just shows you how to learn the tft.drawsprite and sprite.drawString functions, with examples.
      If the LilyGO is really stuck you can try the black reset button on the back and/or the "left" (when holding it vertical with the USB down) button marked "BOT" (boot) in various combinations to clear it

      N

      I found the solution from LILYGO Support itself.
      For anyone wondering how to solve this, you need to hold the RST pin of LoRa high before ESP32 goes to sleep so that LoRa will be active.

      Add this line before going to sleep

      gpio_hold_en(GPIO_NUM_14);

      The full sleep function will look like this.

      void sleep_controller(long seconds) { //Deep Sleep ESP32 Serial.println("Sleeping for " + String(seconds) + " secs"); esp_sleep_enable_timer_wakeup(1000000LL * seconds); // Hold the RST pin of LoRa before going to sleep gpio_hold_en(GPIO_NUM_14); esp_sleep_enable_ext0_wakeup(LORA_DIO0_INT, 1); esp_deep_sleep_start(); }
