SSD1306 INCLUDE for PBP3

[richard]

3. Confirmed the proper oled address with the Arduino (0x3C). I made the change in the demo.pbp file

arduino use a 7 bit address pbp uses an 8 bit addresss , correct address to use is (arduino address)<<1
0x3c<<1 = 0x78

thanks Richard,

I had no idea. I changed the address back to 0x78 just now and I still don't get anything on the screen. I get this ASM Warning in the results window after compiling. Not sure if it matters

[ASM WARNING] SD1306_DEMO_16.ASM (400) : Found label after column 1. (GLCD_BAR?CCBWC)
[ASM WARNING] SD1306_DEMO_16.ASM (432) : Found label after column 1. (GLCD_BAR?CCBWC)

it does matter, it means you are not compiling the code you posted.
Found label after column 1 means the macro you are trying to compile does not exist.

the GLCD_BAR usercommand does not exist in the original include it was added to for louis' setup and only a small subset of input var combinations are
catered for. i have not tested the added code and am not sure what louis wound up with.

get the demo working first

thanks, I went back and used the original ssd1306_I2C.inc. Now no warning when I compile. With no changes to the demo I still can't get anything to show on the oled. To make sure the oled hardware is still good I just checked it with the arduino and it's working fine. I've triple checked my wiring and don't see any mistakes.

i havent used one of those displays for some time ,my other demo for a pic16f1619 used the mssp i2c module
try this ,it worked on my curiosity board , plugged straight in to click socket

unfortunately I don't get anything on the oled

[Ioannis]

Maybe it is nonsense this but, is there a contrast control? I had an issue once on LCD with this.
