Help to integrate these examples on NuttX RTOS

[acassis]

I'm building DirectFB2 on NuttX and thanks to @caramelli help I got it compiling correctly as I documented in this post:
https://acassis.wordpress.com/2023/05/13/how-to-compile-directfb2-on-nuttx/

Now I want to implement some real driver support to get these directfb2 examples working on NuttX simulator and on some real board.

Maybe before getting these examples ported I can create just a basic hellodfb to show "Hello World" in graphic mode.

Please guide me in the right direction to get it working.

Almost all DirectFB examples work perfectly in the NuttX simulator. But this requires having the NuttXFB system module (which is based on the NuttX Framebuffer interface): I plan to push it to the DirectFB2 repository soon (maybe tomorrow).

In addition to the flux package (required to build DirectFB2), another prerequisite tool named directfb-csource is required to build DirectFB-examples for NuttX: https://github.com/directfb2/directfb-csource

A defconfig file for the NuttX simulator is available in the DirectFB2 repository: https://github.com/directfb2/DirectFB2/blob/master/defconfig

The df_andi example is built by default but it is possible to select another example to run through make menuconfig

Perfect! Thank you @caramelli I'll test it! My idea is to create a Makefile like that from LVGL on NuttX to download and compile it automatically. This way will be easier to people test!
