ESP32-2432S028R with alternate TFT driver

[CapnBry]

This was brought up on the Reddit post but for users who own a "ESP32-2432S028R" but you get a display like this:

This is due to the somewhat different ILI9341 driver (ILI9341_2_DRIVER in TFT_eSPI) this CYD comes with. I got the project working by adding this as platformio.ini in the project root directory:

[platformio]
src_dir = ASCII_Aquarium_CYD

[env:esp32]
framework = arduino
platform = https://github.com/platformio/platform-espressif32#v6.4.0
board = esp32dev
monitor_speed = 115200
upload_speed = 2000000
lib_deps =
	SPI
	https://github.com/Bodmer/TFT_eSPI.git
	https://github.com/PaulStoffregen/XPT2046_Touchscreen.git
build_flags =
        -DUSER_SETUP_LOADED=1
        -DILI9341_2_DRIVER=1
        -DTFT_INVERSION_ON=1
        -DTFT_MISO=12
        -DTFT_MOSI=13
        -DTFT_SCLK=14
        -DTFT_CS=15
        -DTFT_DC=2
        -DTFT_RST=4
        -DTOUCH_CS=33
        -DTFT_BL=21
        -DTFT_BACKLIGHT_ON=HIGH
        -DLOAD_GCLD=1
        -DLOAD_FONT2=1
        -DLOAD_FONT4=1
        -DLOAD_FONT6=1
        -DLOAD_FONT7=1
        -DLOAD_FONT8=1
        -DLOAD_GFXFF=1
        -DSMOOTH_FONT=1
        -DSPI_FREQUENCY=55000000
        -DSPI_READ_FREQUENCY=20000000
        -DSPI_TOUCH_FREQUENCY=2500000

• Needed to rename the *.ino source file to *.cpp
• Finally, move the drawButton above drawActionRow so that no function prototype is needed.
• User_Setup.h isn't needed if you build in platformio because the settings are included in the build_flags.

The espressif32 v6.4.0 version isn't important, I just wanted to use one I already had installed.

i believe this is because it's a cyd2usb, would be a sweet port! didn't wanna fck with the drivers myself so i have this jellyfish as a placeholder https://github.com/likeablob/denki-kurage

Thanks for that platformio.ini file - was able to make the changes in the code (moving the function up after getting those errors)... And now, have a working aquarium on my CYD2USB... When my daughter wakes up in the morning, she'll get a kick out if it.

[princessfatrogue]

that's so sweet!! congrats man, she's gonna love it. I'll take a crack at it when I have a chance

[princessfatrogue]

for anyone with a small brain like me who can't seem to gget platformio right on my mac, i forked w the user_setup for CYD2USB here with the arduino file ¯_(ツ)_/¯

I get this result too, any chance this can be an option in the web flasher?

This is the compiled BIN that works on the CYD2USB that we're discussing in this post if you aren't able to compile it yourself.

Thanks for this, but it didn't work, went from the screen shot above to a boot loop (blank screen). I'm using the ESP32-2432S028R but wonder if there's another variant? No big deal.

There are a few variants of the same board and number, unfortunately. Maybe put a picture up of the backside?

Also, did you try this one - https://github.com/princessfatrogue/ASCII-Aquarium-CYD2USB/blob/main/ASCII_Aquarium_CYD2USB.bin)

@CapnBry Thanks for the instructions. I actually managed to get it working this way.
If anyone is interested, I read the flash from one of the CYD's I used to test this and then flashed it back and it works fine.

It's a full 4Mb dump, so it'll take a little while to flash.

Here's the latest 2.2 version for the CYD2USB...

Thank you so much, I must have missed it, my bad

[POWER-PILL]

I'm going to add this to the web flasher today! Thank you all for the help!
