You have a ESP32 VGA.
Connect USB ,VGA and keyboard - I had an old keyboard and mouse ( non USB connector ) with PS2 connector.
Using Arduino IDE upload the Sketch using the Instructables project https://www.instructables.com/Using-ESP32VGA32-Terminal-for-Z80-MBC2/
Connect MCU - three connections for serial in/out&0v. I used thee sent the White Barrows game to the ESP32 VGA. So, the serial out is converted to VGA via the device.
It works.

Thank you. Arduino IDE?... later.! That is why I use GCB!
I had trouble with Instructables site download and forgot my password stuff.
If I got a sketch to work and create a "driver" , what would it do using GCB please?
Serial tx/rx. Is it like using a Nextion display?
Is it text only to VGA?
I have everything except a ps2 mouse as I binned them years ago because they used a ball ie pre laser.
I'll check out youtube and ESP32VGA.

Thanks.
I found a usb to mini ps2 adaptor I had so in theory got all needed mouse, keyboard and vga monitor.
I do not like using Github as it can seem complicated for me , (not the brightest crayon in the box).
I will try to use the device even though not on a plate :( cheers sir.
It is a very new experience and do not know what to expect but is interesting.
A gcb vga display seems a nice idea.. like glcd but keyboard and mouse seems strange.

Hello,
As an alternative to PicoMiteVGA I have connected a Pico via serial to a Lily TTGO VGA32 board, which has the FabGL extended ANSI terminal installed. This gives 640x480 pixels with 16 colours. The extended terminal commands include points, lines, rectangles, polygons, circles, scroll and sprites.
I would like to know how it performs in speed compared to the PicoMiteVGA. This can be tested with a simple program like this, for example:
cls
startime = timer
for n%=1 to 1000
circle int(rnd640),int(rnd480),int(rnd200),,,,rgb(int(rnd256),int(rnd256),int(rnd256))
next n%
print (TIMER-starttime)/1000;" seconds."
On my boards I would replace the CLS and CIRCLE commands with the corresponding ANSI control codes.
I would be grateful if someone could provide me with this test.
Thank you.
If I get any useful info I'll post it here if it's still of interest. stan

I got one of those devices you posted about and not a clue what to do with it.
Did you get it to work as a display?

I mentioned another basic, 2 versions, 1 for touch lcd and another for software vga, which is supposed to emulate a TRS80... sad.

Me too.
Oh. Cant help with that. But, cant you just read the web page.
You load into the ESP32 VGA as per the Instructables page.
Well - yes. Sort. But, you can do loads more.
Well - no. Lots the Instructables page show a GitHub page with all the capabilities.
Amazon sell a little USB to PS2 converter.
Good idea
Thanks.

Let us know how this works. Be good go to know these ANSI controls and the setup of the VGA32 board.
