Hi Rafael.
Following your work from behind 👍
Noticed that the Maven artifact are still stuck on 1.4.1, not 1.5.0 as indicated by the readme.
Maybe are there some glitches in the Travis deploy script?

Kind regards

Reference:

setClipWindow
setMaxClipWindow

Make the virtual driver available for Mac OSX

When in virtual mode, it seems that running snapshot versions built by Travis CI throws 'java.lang.UnsatisfiedLinkError: C:\Users\raffy\AppData\Local\Temp\ucgdisp4751649856605482962.dll: Can't find dependent libraries'.

However, using a locally built snapshot (same version) cross-compiled from my Ubuntu machine do not have this issue and works as expected.

Need to investigate this further.

Error running from Raspberry Pi:

Hi, nice piece of work. I would like to create a menu and ask for some input to the user. Thanks in advance.

Error thrown due to missing include statements

See:

• https://travis-ci.org/ribasco/ucgdisplay/builds/444998260

Merge glcd-emulator-client-java to this project.

In U8g2EventDispatcher, if a listener throws an exception and is propagated to the event dispatcher, the exception will only get logged and not propagated.

The native library would throw an exception due to the library not being found. It is currently using the search path of 'lib/mac/amd64'. The actual arch identifier used is x86_64, so the path should be lib/mac/x86_64

To enable, need to uncomment the following macros in u8g2.h:

#define U8G2_16BIT
#define U8G2_USE_DYNAMIC_ALLOC

In the documentation the pins are defined according to wiring pi standard. Is that still applicable when the code have switched to libgpiod?

See:

Reference: https://github.com/olikraus/u8g2/wiki/u8g2reference#writebufferpbm

New methods:

• String exportToXBM(void)
• String exportToXBM2(void)
• String exportToPBM(void)
• String exportToPBM2(void)

For consideration: https://github.com/vsergeev/c-periphery

The following will be marked as deprecated and removed in future versions (replaced by c-periphery classes):

• CommSpi.h
• CommSpi.cpp

The u8g2 2.7 update now provides the capability to process/manipulate the pixel buffer directly.

TODO:

Add a new method in U8g2Graphics which returns a bytebuffer instance that wraps around the native pixel buffer allocated off-heap.

• getNativeBuffer()

Issues with the current code generation tool

• Needs to be re-compiled every time the controller header file (controller.h) has been updated.
• Requires a local copy of the u8g2 repository for it to work
• Not ci-friendly

Notes:

• Port the cpp code of the gen tool to java. Should be in it's own separate module and packaged as a runnable jar.
• All new controller/font data should be fetched directly from the u8g2 repository (master branch) via Github API.
• Consider automating the code generation when a new display controller has been added/updated in the u8g2 repository.

Make sure that

• Project java sources are compiled/packaged correctly
• Cross-compilation of native library (Linux/Windows) works

Add buffer type property in GlcdDisplay and update the code generation script

Reference: https://github.com/olikraus/u8g2/wiki/u8g2reference#sendf

New method:

• sendCommand(String format, byte... args)
