Re: Obscene amount of Memory
If you have a solder iron, a VGA cable near you, I can send the bin to test. For testing you can just use 5 wires.

Re: Obscene amount of Memory
What VGA pins will be eventually be used Francesco ?
If pins 1,2,3,9,10,12,13,14,15,GND will suffice I'll get the smaller 3+6 Male screw connector, else it will need to be the 3+9.

Re: Obscene amount of Memory
The pins required are just 5. + Ground.
So the 3+6 is ok. However I suggest to take a female to realise a short connection between the esp32 and the connector then you can continue with a standard male-male VGA cable.
Waiting for the connector you can just use Dupont wires directly in the connector of the VGA cable (exactly as I'm doing actually)

Re: Obscene amount of Memory
3,99€ (with free Shipping to France) for "2 to 1" VGA Switch doesn't break the bank... https://www.aliexpress.com/item/1005005 ... 3571938217
Is even cheap enough just to butcher for Annex S3 VGA.
EDIT: 4,58€ for similar, but with more roomy box... https://www.aliexpress.com/item/1005005 ... 3571938217

Re: Obscene amount of Memory
It looks perfect as it is completely manual (it has a mechanical switch)

Re: Obscene amount of Memory
I just received my two modules. Externally they are identical to those of Robin:
Loaded Annex without problems. This is my amount of memory detected:
I know I'll regret it, but I'll try to use this instead of a real connector:

Re: Obscene amount of Memory
I'll send you the wiring information and the .bin.
You can simply start with 3 resistors of 330 Ohm on the 3 colors.

Re: Obscene amount of Memory
Ahah, so now I can add some 330 ohm resistors to the pile.

Re: Obscene amount of Memory
Robin, if you want full colors you need more resistances.
I'll publish a more detailed schematic to obtain 256 colors
Basically for 8 bits, at least 8 resistors.
