Help with VGA module from eBay

JaanDoh

Well I'm back again with yet another problem,
Woe is me....

I bought this vga module from a Parallax distributor
https://www.parallax.com/product/28075

And soldered it all up.
So then I programmed the propeller and eprom with one of the sample VGA getting started programs.
That went okay.

When I came to attaching the module to my propeller
which is situated in a breadboard,
I notice my desktop psu went to 2.9 amps
before I could switch it off
I saw a wisp of smoke coming from the vga module.
So I promptly disconnected it and put it to the side.

I know this is because I did not pay proper attention when soldering the vga module to the circuit board,
Ans o doubt I have bent one or two of the VGA RGB pins an it must be shorting out?

In the meantime, I purchased a replacement vga module from ebay.
Now I need to try this one out to ensure that my Propeller 1 mcu is okay

And I have come unstuck because I dont know how to wire it.
The parallax vga module has TWO pins per colour,
So there is R0, R1, G0, G1, B0,B1 pins.

The replacement module from ebay has THREE pins per colour?
Such as R, R0, R1, G, G0, G1, B, B0, B1...

So how would I wire this into my ciruit as compared to the parallax module?

Thank You for any help you can give me.


EDIT
====
Additionally, I did nothave any pull up/down resistors,
Could this have caused any problems?

The magic smoke is never good.

Resistors are surface mount devices on both board's. Do you have a scematic for the eBay version?

Peter Jakacki

So you have this module here but it is simply a VGA connector with resistors to get the analog VGA values. In your case you just use the higher numbers like R1,R2 etc. The only difference you will notice if you get that wrong is the intensity but you will still get a picture. It's just a dumb passive module.

The module may also have a weaker intensity because they have use 75 ohm termination resistors on it yet the monitor already has 75 ohm termination. If your color signal is weak it's simply a matter of flicking off the 75 ohms with a hot iron.

Hiya Mike and Peter

The schematic in the link that Peter Jakacki has posted is the EXACT one,
Its a WaveShare module as I discovered earlier whilst at work today.

I guess too, that Peter has posted the resolution?
Which was to use the HIGHER pins
like R1, R2, B1, B2, G1 and G2

Out of the possible choices which were
R, R1, R2, B, B1, B2, G, G1, G2

Well I'll give it a go and keep my fingers crossed Lol

Thank All for the help guys.

Update

Well that worked perfectly.
I didn't need to flick of the resistors
And the display was bright as you like.

Thank You Very Much.

Which VGA program are you using in your photo?

JaanDoh

I am using the AN004-GUI-StartVGA-v1.0
demo program from Parallax.

I downloaded it from the OBEX.
The photo is the same as the one in the attached PDF on page 12
Labelled as Figure-6

Thank you, I haven't tried that one yet.
