Hello guys, I've actually a working FreeRTOS port (James Walmsley's port updated to version 8.0.0 by myself) and access to the framebuffer of my Raspberry PI (University of Cambridge's explanations rewritten in C by myself). I would like to add some graphical interface now, and checked out different solutions. My proper library (written several years ago for PIC18 and PIC32) is easy to port, but has only very little possibilities (character display, simple forms like rectangle, circles,... and image support for my proper image format). Many other big graphical libraries are not free. So, I ended up with µGFX which is free and seems to have quite a lot of features. My question is, is there anywhere a porting guide to bring µGFX to life on my Raspberry? Are there any functions like "SetPixel" and "GetPixel" to implement? Under GDISP/framebuffer there are some interesting files. Would it be sufficient to change the following functions? gdisp_lld_init, gdisp_lld_draw_pixel, gdisp_lld_get_pixel_color Is someone else interested in my project? Just send me a pm and I'll share the code with you. +++ macload1
