Gamebuino forum

yes you read that right gamebuino DS (dual screen) module



also yes my red gamebuino looks amazing

this needs the u8glib: https://code.google.com/p/u8glib/
helo world code:

Code: Select all

//imports the library's
#include <SPI.h>
#include <Gamebuino.h>
#include <U8glib.h>
//creates a Gamebuino object named gb
Gamebuino gb;
//creates the ds object for the oled sceen
U8GLIB_SSD1306_128X64 ds(U8G_I2C_OPT_DEV_0|U8G_I2C_OPT_NO_ACK|U8G_I2C_OPT_FAST);


//sprite 48,64

That is looking awesome!
Do you mind releasing some more technical details?

what do you want to know

its just ssd1306 oled display over I2C (from ebay) and 4 wires

im straight up using the u8glib in the pong example
only wierd thing im getting is on start up you will get noise on the oled screen

just tested some bitmaps, bit difrent format atm need to fix that


the display takes images as a byte array similar like the gb format exept for the W H at the bigining of the array
using u8g drawing with

Code: Select all

u8g.drawBitmapP(x,y,w/8,h,imageArray);

Cool

so the pricing of the oled is resonable and you sude get one under €10
a solder iron, proto-board and 4 female header will help ofcource

pin out from left to right on gamebuino, will work on ether connector
0v --- gnd
3v3 --- vcc
da --- sda
ck --- scl

if you have intrest in this module and wish to have one maybe a bit more sleeker on a pcb, we can get some made if there is enugh interest

Did some soldering for probebly the easyest conection ever

It might seem insane to say right now, but why not use the same kind of screen that the GB has?

Other than that, this is great!

wel mainly since the nokia 5110 screen is realy realy bad (i mean have you seen that ghosting?)
also hey u know that arduboy thing? yea you basicly play there games with some tweaking

and the higher resolution is realy nice to have

but but the ghosting is one of the charms of it

sure it has its scharms but not all games work well with its
anything with fast movement becoms a mess
this little thing is just an option for you to add

anyway plz tell me if you guys are interested in more of this
other i2c sceens work aswel btw
