Please free to modify the example sketch. It's useful information.

Hi all,

Just bought this display. Am planning on building an Eagle part, can anyone tell me what the vertical distance is between the pins and the screwhole?

Thanks!

This is a tricky one to answer because I don't have access to the original design files and the distance is so tiny. Measuring it by hand with a digital vernier I get it to be about 1/3 mm from the centre of the connector holes to the centre of the mounting hole.

Hi andrew,

Thanks, have created the part and attached it, maybe someone else has a use for it. All headerholes, screwholes and outer dimensions are correctly placed according to the data in the dimension-image, the image of the display itself in the package is a rough estimate. When I receive the part I will update the attachment if it needs tweaking. (If you are going to use this part in Eagle, please check all dimensions)

Cheers!

EDIT: Part has been updated so pins on OLED will fit. Sorry!

Is this display available without the pin header?

I'm afraid the headers come pre-soldered by the factory.

Ok, but be aware that on the Eagle part posted above, the pin holes are sightly too small. I had to desolder the pins on the display, and replace with smaller ones.

HI, I tried this example, but I'm getting the following error: "cpp.elf section .text will not fit in region text".
This occurs when I'm using the U8glib.h library.

What's wrong?

Please help!

Do you mean the example that is in the first post of this thread? What Arduino board and version of development are you using? Are you also using the U8glib library from the first post?

Hi All,

I'm trying to get this display working on a custom board using an ARM chip and IAR but haven't been able to get it to do anything after hours.

My startup routine is (all tested with multimeter in debugging):
  • Reset pin low
  • Wait 10us
  • Reset pin high
  • Wait 8us
  • Send 0xAE (DC low, CS low) - Display on
  • Send 0xA5 - Whole screen on
What am I missing?
  • I've tried inverting and setting contrast to no effect.
  • Is it OK for the SPI clock pin to only run when sending? In code the click pins and data pins are manually set as needed (should run about 12Mhz when sending, but high otherwise).
  • I started with an IAR provided graphics library and discovered it was entirely wrong, so it's a modified version of that.

Thanks in advance for your help! :)
