uOLED-128 Picture viewer

I was inspired by Ray's work with the TFT screen, and having recently
acquired a uOLED-128-G1, I did a conversion of spudview for it allowing you to
display 128x128 Raw .PPM images (Can be created with Gimp)
Unlike TV, It is surprisingly easy to communicate with these displays.
Attached is source code, and photos. Requires SD, copy your files and adjust pin settings.

I can't thank you enough... and your esp seems to be working just fine. I wanted to integrate the 128 into my PropPhone... much smaller than a video projector[noparse]:)[/noparse] AND I hooked everything up and nothing worked. Now I don't have to think... I can just do as you've done[noparse]:)[/noparse]
ThankUthankUthankYOU

May have to give this a try. I need to do a little reasearch on the difference between the G1 and the GMD1 though.

@rjo, glad it's useful to you.
Been doing some testing to see if I can get it doing video, but it just doesn't seem to
be fast enough for plot drawing. [noparse]:([/noparse] I'm playing with the idea of doing some kind of
gaming with it. I'm picturing a Protoboard with some directional pushbuttons, fire button
and this screen. Would make a neat hand-held game device.

I was playing around with those ppm files in my hex editor and came up with this bmp
If this looks right, this tells me you could use bmps with a little different offset. (duck the shoes here from the Linux people)
Couple things, your image seems inverted & upside-down. (See my first post)
Some of the colors are a bit off. also I suspect that bmp's might be heavier than .PPM, but at this size probably not by much. [noparse]:)[/noparse]

ImageJ offers the conversions... is cross platform and is the fastest Java image processor on the planet... and the support for automated processing is incredible.
When we get to robot vision... "gimp" is going to look like "lame."
Here's a link to it:

I think these units share the same command structure (except for SD card access)...
If the "Display Image" button works, I could modify it easily to make 128x128 images...
