Happy to make the contribution, your after sales support is excellent, giving a "tiny" thing back is a way of saying thanks.

I like how you have added the character spacing to the font file. A very sensible approach that makes its easy to tweak.

Now, with all the software issues resolved, I need crack on and build a housing for them so they can be installed on my model railway.

Cheers for that. Please feel free to post a picture when it's finished I'd love to see it.

Error compiling for board WeMos D1 R1.



This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
any idea on what this error is caused by? bit disapointing... ive heard something about the fonts that's causing this?

I've attached an updated version (V0.8) of the library to this post. Unfortunately as it's the weekend I can't test it but hopefully this should fix the problem. Can you give it a try and let me know if it's fixed and I'll add it to the first post.

hey! great library btw, is there any way of retrieving the state of a pixel? by that i mean if pixel at y:13 x:10 is on/off. thanks! I assume it can be retrieved from the buffer but I don't know how.

Thanks. As it was an simple addition to the library I've attached an updated version (still V0.8) which includes a GetPixel() function.....

Code: Select all

HCuOLED.GetPixel(X, Y);
Get the current state of a pixel where:
X is the x axis coordinate of the pixel
Y is the Y axis coordinate of the pixel

Returns: A boolean value representing the state of the pixel at coordinate X,Y

Again, if you could let me know if it works and I'll get this updated version added to the first post.

thanks for all the great help! the v8 library works now, i can display on my 0.66" OLED fine and the get pixel function works as well, keep up the good work. :D

Thanks again for confirming. I've now added this version to the first post.
