Hi there,

I love the idea of this device. But, I just tried mine out, and (a) the display has a very poor viewing angle, and (b) the viewing angle is mounted horizontally instead of vertically. That means the only good way to view the screen is from the right, and unless you hold it at a very sharp angle, your eyes see two very different pictures. It's driving my eyes crazy, and makes it unusable for me. I hope you switch to a much better display on the next revision.

best wishes,
Peter

How could I go about measuring the battery voltage? Is it as easy as setting some ADC pin to input and measuring that voltage?

如题，可以提前卖我一个吗

I'm trying to decide if I want to buy the unit. But in looking at the photo of the unit, I don't see any place I can connect my antenna to it.

Perhaps this is not the unit I can use. I called your China office, but they apparently didn't know much about the product.

Thanx
John D.

Hello,

I'm wondering if it is a faulty t-deck or something that I can fix on my own. After trying different stable versions from meshtastic, T-Deck keeps crashing.

Hello,

While I was reading schematic, I discovered four hall effect sensor (UZ1-4, IC : AN4884). I didn't find them on the PCB; I tried to read G_S (Pin 15) with analog pin , played with a magnet over the PCB but nothing. Do you have more infor about these sensors ?

does anyone have the PDF documentation document somewhere?
thx

Is the keyboard interrupt pin connected?

Does it register high or low when a key has been pressed?

I have a T-Deck working nicely with the display, using the GFX Library for Arduino by Moon On Our Nation.

I have also got the T-Deck working with the SD Card interface, using the SD library in the ESP32 core, by adding the definition:

#define SDCARD_SS_PIN 39

and changing the SPI definitions in the file:

/Users/david/Library/Arduino15/packages/esp32/hardware/esp32/2.0.12/variants/esp32s3/pins_arduino.h

to:

static const uint8_t SS    = 39;
static const uint8_t MOSI  = 41;
static const uint8_t MISO  = 38;
static const uint8_t SCK   = 40;

However, when I use the SD Card the display stops working.

Can anyone provide sample code showing how to use the display and SD Card interface at the same time?

Could ESP32-S3 pins 28 to 30 and other currently non-terminated pins be routed to some pads or generic via(s), perhaps a header of some kind. This would make it easier to expand the options of this PCB.

Hello !

I read the pinout from utilities.h and I write a micropython code to mount the SD card :

from machine import SPI, Pin
from sdcard import SDCard
import os
import hw

power_en = Pin(hw.PERI_POWERON, mode=Pin.OUT, value=1)

clk = Pin(hw.SPI_SCK, mode=Pin.OUT, value=0) # pin 40
mosi = Pin(hw.SPI_MOSI, mode=Pin.OUT, value=0) # pin 41
miso = Pin(hw.SPI_MISO, mode=Pin.IN) # pin 38
cs_sd = Pin(hw.SDCARD_CS, mode=Pin.OUT, value=1) # pin 39

spi = SPI(1, baudrate=int(hw.SPI_SPEED), sck=clk, mosi=mosi, miso=miso)

try:
    print("SDcard")
    sd = SDCard(spi, cs_sd)
    print("Sdcard mounted")
    os.mount(sd, '/sd')
except Exception as e:
    print(str(e))

I always got "OSError: no SD card". The SPI works since I can use the TFT display and I check on the schematic that ESP_SD_CS is on IO39 (real pin : 32).

Do you have any idea ?

Hello,

Please provide a schematic that is readable.

Thank you.

“esp_vad.h: no such file or directory ”
Can’t seem to locate said missing file

i followed all the instructions on setting up the IDE for the tdeck, tried reinstalling the arduino IDE, both on linux and windows, and everything the code compiled and uploaded just fine to the t-deck, but upon uploading the code the t-deck showed nothing, the screen wouldnt even turn on, the backlight of the keyboard would flash once every reset but nothing would happen on the screen, please help

I have broke the screen on my t-deck v1.1. Is it possible to order a replacement?

I tried to flash micropython (generic esp32-s3) onthe board, the flashing went well, however UART doesn't show on usb anymore. Any guide how I can I access/enable the usb uart so I can reflash the chip?

My antenna connector ripped after trying to swap from the default to a better antenna.

Is there any way I can reconnect the antenna (original or better) or maybe fix the connector?

Sincerely, Mirko

Hi There,

All examples seems to compiling and working fine, except for the UnitTest example. It seems to be looking for lv_conf.h

All libraries are correctly installed. Maybe a file is missing ?

Compilation error: 'bool enableInterrupt' redeclared as different kind of entity

the trackball wont do up or down inputs

I'm attempting to solder the header pins onto the board and realized I probably should ask around for tips-and-tricks first. I think the keyboard should come off since it looks like a tighter fit than what I'm comfortable with, but don't really see how to do that.

I have 3 t-decks. Unfortunately one of them corrupted during a download, since then I have been unable to get it to take an new firmware.

I can (sometimes) get it to boot into the rom bootloader mode by holding down the trackball while resetting, however, once I try to use the esptool it finds the com port, but times out in writing.

esptool.py v4.5.1
Serial port /dev/ttyACM0
Connecting....

A serial exception error occurred: Write timeout

I have tried this also on other computers with identical results. I've also tried putting my working T-decks into bootloader mode and while I can get them to bootloader mode the results are identical to my failed T-Deck.

The good ones will still take updated firmware while running normally, but the failed T-Deck will not, as it continually resets the USB connection.

With trace enabled in esptool I get the following:

esptool.py v4.6.2
Serial port /dev/ttyACM0

A serial exception error occurred: Write timeout

I've tried forcing the chip with --chip esp32s3 (and esp32) as well as various baud rates. Everything I try fails with the write timeout.

Connection is successful and I get data from the chip when I do:

But any attempt to write or to erase the flash fails with a write timeout.

This is reproducable on all 3 of my T-Decks when in bootloader mode (and on multiple computers), but like I said, 2 of them can get flashed normally in the non-bootloader mode.

T-Deck 433 Mhz stuck in boot loop, bricked during flashing to newest version and will not turn respond.

Blue LED above RW1 turns on when powered by an external power source, but not battery. Computer will not recognize com port when plugged in and nothing appears on screen.

I added some functionality to the keyboard firmware, I figured I'd link it here in case you or other people want to take from it or add to it. Thanks! https://github.com/hasn0life/t-deck-keyboard-ex/tree/main

Hello,
Would It be possible to have the 3D of the PCB so I can adjust properly my 3D printed shell.
Thanks for the great job.

hi,

i received T-Deck recently in the mail and wanted a case.

there are design files in this git repo but i didn't have success using them. can you provide any instructions, or photos on their usage?

• T_Deck_1.stp: appears to be bottom case only, no front cover. is that expected?
• T_Deck_2.stp: i printed this, but the top cover doesn't seem to fit. there is parts of the model in the way where the keyboard/trackball is supposed to go and i didn't want to disassemble my t-deck keyboard for fear of breaking it.
• T-Deck.dxf: i can't use this file, does not work in freecad, free 3d editor for linux
• T-Deck.stp: doesn't look like a case.

i'm using freecad on gentoo linux to view the design files. it would be great if there was better support for making cases here. 😄

Hello,

I am trying to install Meshtastic on my t-deck but when I connect and select the device it stays in "connecting" mode. Can someone please help me? Otherwise I will have to return this device, I have been unable to find a solution on my own.

Trying to figure out what PIN is matched with the keyboard backlight. I made a screen inactivity timeout, but the keyboard backlight remains on for it. Anyone have some insight?

Does any know if there is a port of marauder for the t-deck?

Can you add an example sketch on how to generate a simple tone to play on the built-in speaker (over I2S, I assume?).

Hello, I bought this T-Deck directly at lilygo.cc. I receive it yesterday, I have been trying to flash it but it doesn't respond. There is only a bluelight in the rear and it blinks once when I turn the unit on. I changed cables and used two computer a Macbook and a Windows laptop, none of them detects the USB connection.

As instructed, I keep pressing the scroll wheel button and turn on the unit and then release the button. I also mixed it with the reset button, but nothing happens. Looks bricked

Is there any other procedure that I should follow?

t-deck runs fine on usb l8st mesh firmware installed when powered on with usb it shows the battery fully charged
but when i disconect the usb and power on it will not power up its as if the battery is not there

any help thanks
