dustinwatts / esp32-touchdown Goto Github PK

It is on /Users/{user}/Library/Arduino15/packages/arduino/hardware/avr/{version}/boards.txt
Maybe it is worth updating the wiki

Hello,

are they any plans to make a batch of full function pcbs? or a crowdfunding project?

Not everyone have the skill to make a one board?

Hi Justin. Can you help me use your ESP32 TouchDown V1.0? I am unable to get any output on the screen, I am using version 2.5.34 of the TFT_eSPI library and in the library folder (../libraries/TFT_eSPI) I have replaced the file User_Setup.h with yours (see link below). Compilation runs without error messages but there is no output on the screen. I hope to hear from you.

https://raw.githubusercontent.com/DustinWatts/esp32-touchdown/main/Examples/TFT_eSPI%20Setup%20Example/User_Setup.h

I followed your tutorial to configure the pins of the Esptouchdown as follows :
#define TFT_BL 32 //TFT_LED
#define TFT_MISO 19 //SDO
#define TFT_MOSI 23 //SDI
#define TFT_SCLK 18 //SCK
#define TFT_CS 15 //TFT_CS
#define TFT_DC 2 //DC_RS
#define TFT_RST 4 //TFT_RESET
#define TOUCH_CS 21 //I2C SDA
#define SCL_I2C 22 //I2C SCL

I tried to install an example you attached to the repository, but it just comes up with a "gray screen" like in the picture.
So I tried to use the Arduino_GFX library which allows you to create a software SPI and the result does not change.
Where am I doing wrong ?

Hi, can we use other screen options like bigger higher resolution ones? are there a plug and play alternatives there for replacing ILI9488? Can we make the screen use a bit more abstract and interchangeable?

Hi Dustin. A while ago I bought your TouchDeck and it worked out of the box including touch control. I am now trying to install something else and have tested with ESP32_TouchDown_Drawing.ino and ESP32_TouchDown_Keyboard.ino. The sketches compile without errors and start up fine, but the touch function does not work. The touch library (https://github.com/DustinWatts/FT6236) is installed correctly so that shouldn't be a problem. Can you help me? Regards, Hans.

any suggested battery and or wiring?

Thanks for sharing your design. I couldn't find the TFT you are using in the BOM. Can you please add it with model number or a link to a vendor?

(By TFT I mean the entire TFT subassembly, not just the TFT or touch controller ICs).

Thanks.

Hi there,
Fantastic project! Due to worldwide product shortages, I would like to replace several hardware components and print a customized PCB using substitute parts which I have in stock. However KiCad folder only contains 4 of the 24+ total footprints in your PCB file:

Hirose_FH12-40S-0.5SH_1x40-1MP_P0.50mm_Horizontal_flipped.kicad_mod
INGHAi GSC1625YB-3V4000.kicad_mod
microSD_TF-01A-C91145.kicad_mod
TS-1088R-02526.kicad_mod

Would it be possible for you to update the following folder to include all KiCad footprints (.pretty folder)?

esp32-touchdown/Hardware/ESP32_TouchDown_Rev1/ESP32_TouchDown_lib.pretty/

Thank you and Kind Regards

Is there any chance the case models could be posted in STEP or IGES or perhaps Solidworks native format?

(Solidworks doesn't like working with STL files.) It's not a showstopper to have to start from scratch but it would be nice to have a starting point for designing a new case.

I am trying to load new firmware to the Touchdown using PlatformIO. I have not tested with Arduino IDE.

The only way I can get it to flash is to use the BOOT and RESET buttons. Is this normal / expected ?

The examples are broken due to the removal of
'''
#define TFT_BACKLIGHT_ON HIGH // Level to turn ON back-light (HIGH or LOW)
'''

Currently, the screen remains empty since the TFT_BL pin defaults to LOW. Maybe add a simple PWM function to give the user an idea of how to handle the brightness of the backlight such as:
'''
void TFT_SET_BL(uint8_t Value)
{
if (Value < 0 || Value > 100)
{
Serial.println("Error setting TFT Backlight level");
}
else
{
analogWrite(TFT_BL, Value * 2.55);
}
}
''' (Modified from Bodmer/TFT_eSPI#142)

Another solution would be to inform them that they are responsible for enabling the backlight.

Hey there, awesome project!

Sorry for the dumb question... but what is the recommended screw size for the four (4) mounting holes on the corners of the PCB (both diameter & length) when using the printable cases located within this repo?

I tried to find the info in this repo and on Tindie but wasn't able to find it anywhere 😢

Thx!

I like this keyboard klawiatura.wordpress.com/
because volume control, big knob/potenciometer is better than keys.
Is possible add virtual knob for wolume? of linear potenciometer too?

for example for tempest game knob or linear volume control or object 3d manipulation.

second idea from https://klawiatura.wordpress.com/wersja-mini/ is moving panel info to your keyboard.
Why not free up screen space? clock, ethernet indicator, whitch screen You use, network metter etc. Why not movit this information to keyboard?

Hi Dustin,

love the design and the idea.

I bought all the products you recommended, pcb from pcbway ILI9488 screen and ESP32-WROOM-32D and ive followed your youtube tutorial https://www.youtube.com/watch?v=s2X4BQ9VmEU&t=515s&ab_channel=DustinWatts.

I've got an issue which im sure is on my end with my config.

I have a white screen it strobes a little bit my user_setup.h is exactly as the video any suggestions on how to fix?

Hello!
Is there a way to set the rotation of the screen in the config? I have mine mounted in a stand that will require it to be flipped vertically.

Thanks!

Using R61529 is a good alternative, it is compatible with ILI9481 code, supports RGB565 or RGB666, IPS screen, supports i80 interface 8-bit or 16-bit

Hi there,
Is there any micropython + lvgl (https://github.com/lvgl/lv_micropython) already built firmware supporting your board?
Thanks and best regards.
