Graphics Arduino Due ST7735

Hi there

If I try to add a graphics node I can’t compile the patch, if I removed it no problem to compile. I got that error massage:

Begin compiling code for the board Arduino Due (Programming Port) :package:

I’m using already the xod version 0.35.0

@m-b Hi!
Due to the new update, the c++ implementation of nodes has changed. The documents and case studies need to be updated.
By now, you can rewrite your bitmap according to the following structure.
Example:

nodespace {
    static const unsigned char icon[] PROGMEM = {

    0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00

Hi

many thanks for your support first!
I’ve tried to do what you have mentioned, I also follow you structure with your example too. But no sucess right now!
Even if I copy the full example ist not possibel to compile it.

I’ve got that error:

Hi @gabbapeople

I downgrade XOD to 0.34 and try to compile the patch ( like mentioned in my first post above) to the DUE. But even in older version it wasn’t posibel to compile and upload the patch.
Now with XOD 0.35.1 I even update the graphics library too, still have exactly the same error like mentioned before.

Have you any idea to solve that?!

@m-b, I’m sorry for this bug. I’ll fix it next XOD update. By, now try this:

Bitmap myBitmap = Bitmap((uint8_t*)icon, 2, 16, 16, 0x0000);

Should work.

Hi @gabbapeople

Thanks that works perfect!
PS. Isn’t it easer to update the graphics library as to update XOD?

7

Hi @gabbapeople

do you have a prefered tool for converting image into byte c arrays?

8

@m-b, my choice is:

Rgb:

Bw:

Ditheritng:

9

I can fix the graphics library, but without official XOD release you will see the changes only in DEV XOD version https://github.com/xodio/xod

10

It was just a idea for an easy going for you with updating the library.
Right now it works fine for me, I just have the problem to convert it into the right array. I now that it should been two byte with RGB565 but sometimes …
