Quick Start

Arduino

Arduino:

Click "File" in the upper left corner -> Preferences -> Additional Development >Board Manager URL -> Enter the URL in the input box. (ESP32S3 is a new chip, and the SDK version needs to be version 2.0.3 or above) https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Click OK and the software will be installed by itself. After installation, restart the Arduino IDE software.

Search for ESP32 in Tools->Board Manager and install ESP32-Arduino SDK

Copy all files in the lib folder to \Arduino\libraries

Select the settings as shown. Note that the FLASH size partition and size may be modified depending on the board.

PlatfromIO:

PlatformIO plug-in installation: Click on the extension on the left column -> search platformIO -> install the first plug-in

Click Platforms -> Embedded -> search Espressif 32 in the input box -> select the corresponding firmware installation

ESP-IDF:

The installation method is also inconsistent depending on the system, it is recommended to refer to the official manual for installation

Micropython:

tft_config.py is already built into the firmware. The examples in the examples directory can be used directly.

For detailed function query, please refer to the following link.

[Micropython doc]

Tips

The program can be written normally, but there is still no display after writing
1. There are factory test files in the firmware folder, which can be flashed into the board to check whether the board is normal. If there is still no display, then it can be judged that there is a problem with the board or the screen
2. Delete the <TFT_eSPI> in the libraries, and replace the <TFT_eSPI> in the folder of the main page to the libraries directory
3. When opening the Arduino IDE, it prompts whether to upgrade the library, please choose not to upgrade, otherwise it will overwrite the configuration of the <TFT_eSPI> display

The board uses USB as the JTAG upload port. When printing serial port information on USB_CDC_ON_BOOT configuration needs to be turned on. If the port cannot be found when uploading the program or the USB has been used for other functions, the port does not appear. Please enter the upload mode manually.
1. Press and hold the BOOT button , While still pressing the BOOT button, Insert USB
2. Release the BOOT button
3. Upload sketch
If the above is invalid, burn the binary file to check whether the hardware is normal

t-dongle-s3's Issues

3D_File. invalid filename

Windows chokes on the new folder name 3D_File. Can't end with a dot.

How can I turn off the LCD?

The dongle gets a little hot and I don't use the LCD but the backlight is always on. Hoe can I turn it off?

Header on side

My device has what looks like a 5 pin JST connector on the side.

I couldn't see from the schematics what this is connected to.

Card Mount Failed due to ESP_ERR_TIMEOUT

If I use the Arduino IDE (v2.0.1) with arduino-esp32 2.0.5
https://github.com/espressif/arduino-esp32
I can add the SD_MMC.setPins line and run the SSDMMC_Test and read from some microSD cards with no problem.

However using PlatformIO, building and installing the Factory project results in the Card Mount Failed error.

E (4001) sdmmc_req: sdmmc_host_wait_for_event returned 0x107
E (4001) sdmmc_sd: sdmmc_check_scr: send_scr returned 0x107
E (4002) vfs_fat_sdmmc: sdmmc_card_init failed (0x107).
[ 4231][E][SD_MMC.cpp:138] begin(): Failed to initialize the card (0x107). Make sure SD card lines have pull-up resistors in place.
Card Mount Failed
scan start
scan done
5 networks found
etc.

I see that 0x107 is ESP_ERR_TIMEOUT

apa102 module not implemented in firmware - potential fix

apa102 module is not available in firmware.

Uploading a generic Dotstar driver (https://github.com/RobertJBabb/micropython_generic_apa102/blob/master/generic_dotstar.py) allows the LED to be accessed easily like so:

import time
from generic_dotstar import SpiDotStar as SPIDotStar
from machine import SPI, Pin

clock = Pin(39)
data = Pin(40)
num_pixels = 1

print('Testing MicroPython 1.10 SPI DotStar Compatibility Class')

spi = SPI(2, sck=clock, mosi=data, baudrate=1000000)
pixelp = SPIDotStar(spi, num_pixels)
pixelp[0] = (0, 255, 0)
pixelp.show()
r, g, b = pixelp[0]
time.sleep(2)
pixelp.deinit()

Fail to upload factory and default firmware

Hello,

I just received the device then plugged-in it boot and works
I tried to compile/upload with PlatformIO the example/firmware is fail while uploading, the display is black
I tried to upload the default firmware with esptool it fail at 50/60% (screenshots)
I tried to change the driver (some issue on intenet) didn't change anything
I have other TTGO Display, etc ... all other works, compile and upload.

I don't know what to do,

I need to upload the firmware with esptool to validate it works
then uderstand why I can't upload from PlatformIO

I switch port, reduce the bandwith, etc ... nothing change
Now when I monitor the device from VSCode I have a loop :

Slow Read Speed

Current using a bat file to create a bin file of lilygo but its super slow anyway i can speed this up.. Im guessing it has to do with the sd card slot but I don't use that.

Hello,

On default factory firmware the wifi function is not executed.
It is not scanning for APs

0xffffffff invalid header in micropython (T-Dongle keeps disconnecting from port)

0xffffffff invalid header error in MicroPython. Also T-Dongle keeps Disconnecting from serial port. Same behavior if i use ArduinoIDE or check ls /dev/tty.* I tried to flash with esptool.py using command line also. Same results. Please help. I am using Macbook Pro with MacOS Monterey version 12.6.3

Can't upload sketch after using Lilygo as a USB keyboard and mouse emulation

I have uploaded a sketch that transforms my lilygo ESP32-S3 in a USB keyboard and mouse emulator
The sketch works, but I can't upload a new sketch as the serial port is then disabled.
How can I erase the sketch or upload a new sketch ?
Is it possible to have serial port and USB keyboard and mouse emulator at the same time ?
(It's possible with an ardunion leonardo)

#include "USB.h"
#include "USBHIDKeyboard.h"
#include "USBHIDMouse.h"

USBHIDKeyboard Keyboard;
USBHIDMouse Mouse;
uint8_t buf[200];
void setup() {
// open the serial port:
Serial.begin(115200);
// initialize control over the keyboard:
Keyboard.begin();
Mouse.begin();
USB.begin();
Keyboard._onGetDescriptor(buf);
}

void loop() {
// check for incoming serial data:
if (Serial.available() > 0) {

// read incoming serial data:
char inChar = Serial.read();
Serial.print(inChar);
// Type the next ASCII value from what you received:
Keyboard.press(inChar);
Keyboard.releaseAll();

}
Mouse.move(20, 20, 0, 0);
Keyboard.press('Q');
Keyboard.releaseAll();
delay(3000);
}

tft_config.py : wrong PIN assignment?

Hi,
i'm having trouble getting the display to work, and while double checking I found the following:

on the schematic and in other bits of code, LEDA (backlight?) is assigned to pin 38
#define TFT_LEDA_PIN 38

in python it is PIN 37
backlight=Pin(37, Pin.OUT),

setting backlight to pin38 seems to make tft.on() and tft.off() work, albeit reversed... it's active low i.e. tft.on() switches the backlight off.

TFT is not working

I cannot use any exemple of TFT (I used the documentation of the device and the indications on the git page). When I compile and write the app to the device, the device it stops working, even the serial connection it stops.

converting image to byte array

this is not an issue, it's a question since I couldn't find the tool

what tool was used to convert an image to this array here:

T-Dongle-S3/example/Factory /logo.h

Thanks

Upgraded case 3d model

Dear,
Your support team told me that you made modifications on the design of the case to fix screen and button issues.
Could you please consider to upload the 3d model so people could fix their dongles by 3d printing a new case ?
Thank you in advance.
Have a great day,
Julio

compile issue with last esp-idf

Hi,
I could not compile it with esp32 v5.x and I needed to use tiny midi usb which only included in that version
all the compiling issues are with the LovyanGFX library
I manage to compile with esp idf v4 but I can not use that version in my project

please update the current examples to the last esp idf or provide a screen example that compiles with the last esp idf
thanks

Factory Code

The Example Factory code does not work, Will compile and load in Arduino but no display, displays blank even though LED color cycling is working, looks like any sample code to test the display is not working, maybe TFT_eSPI changed

TFT.ino in example/TFT does not draw to screen

Using latest Arduino IDE. TFT_eSPI library is installed. girl.h, logo.h, logo2.h, pin_config.h are all in the same folder as TFT.ino. Code will upload but display remains on and blank. Please include all details needed to draw to the screen. Are there any config files that need to be changed?

Can't access SDCard with micropython

Trying to access the SDCard. I'm using the following minimum code:

import umachine
import uos

sd = umachine.SDCard()
uos.mount(sd, '/sd')

I get:

Traceback (most recent call last):
  File "<stdin>", line 5, in <module>
OSError: 16

Power the dongle by the QWIIC connector

Hi, can the dongle be powered by the QWIIC connector on the side? If so, what voltage?

It might seem redundant since it's powered by the USB, but I'm trying to get it working with a 3-volt battery. (in the smallest form factor possible)
