Good day. Need help with board VGA32V1.4 The uploading of the file system image was successful. Compilation and firmware also went 100%. However, when I connect to a monitor or TV, I get a "No sync." I checked the pins from https://aliexpress.ru/item/33014937190.html?spm=a2g0s.9042311.0.0.f94833edo203fa&sku_id=67232648779 with those that are assigned when defining the VGA32V14 constant, they are set correctly. When power is supplied from the USB, the board shines with a blue LED, when the power supply starts, the LEDs on the keyboard blink. No more reaction. What else can I try to do?

Hello, you should run the monitor task and post the logging output here.

it think this is problem from resolution or aspect ratio. because flash from your ZX-ESPectrum-Wiimote/tree/lilygo-ttgo-vga32 project work on my 4:3 monitor but with 16:9 constant

You could try increasing the value in line 97

if (ESP.getFreeHeap() >= 65536)

from 64K to 72K, 80K or even more. 4:3 uses 320x240 graphic mode, instead of 360x200 for 16:9, and needs more RAM.

Hello, i am a newbie to the world of Arduino and ESP32. Kind have the same problem here, almost.

I have follow the instructions in the Github pave and copied the boot.cfg.orig file. "cp data/boot.cfg.orig boot.cfg"

After compiling and flashing the TTGO VGA32 keeps rebooting.
