Re: Obscene amount of Memory
Can you anticipate the values and design of the resistor network that you will use for your VGA project?
I have ordered two ESP32 S3 N16R8, but I will not receive them (hopefully) until the 19th of this month.
It's for doing something while they arrive.

Re: Obscene amount of Memory
I did not yet implemented the resistor DAC, I'll give you some infos soon.
For the pinoout, I think that any pin can be configured freely.
The interface requires 8 pins for the colors and 2 for the sync
For 8 colors, only 5 are required

Re: Obscene amount of Memory
Is looking hopeful... my S3 N16R8 has same markings as yours, the only noticeable difference is that mine is black but yours is purple (pcb that is).
Any idea what gpio is used for the dev kit neo, to save me sequencing through all the pins ? (its not mentioned with the devkit pinout).

I never tried to use it

Re: Obscene amount of Memory
Thanks for looking Francesco, but when placing an order the cheapest shipping option is 20 euros, bringing the total cost to almost 37 euros (so I didn't order).

Re: Obscene amount of Memory
The neo is not connected by default - I buzzed it out and it seems to need soldering across the pads labelled RGB to connect data-in to gpio 48.
Haven't tried it yet though, cos the N16R8 prices have already started rising, and I don't fancy zapping any of the 1.8v circuitry doing some unnecessary arc-welding just for the sake of an onboard neo-pixel (I'll do it when soldering the female headers).

With some resistors and with the module N16R8
The color scale (332) 3 bits red, 3 bits green, 2 bits blue
The full 256 colors

Re: Obscene amount of Memory
After seeing the proof that VGA is possible, I ordered another three N16R8's while still at 7 euros, so should hopefully make a total of 5.
That gave courage to solder the female headers and the RGB solder bridge, which does connect the neo to gpio 48.
