How using port uGFX #118

Closed nathanLoretan closed 7 years ago

Hello, I've heard that it is possible to use the graphic functions from ugfx library with the OS frosted. I want to know how can I link both?

This is currently a joint work in progress between insane-adding-machines and the ugfx.io community. There is no port available yet, but we'll keep you informed when we have a working uGFX port compiling & working on frosted.

I know. The port to bind uGFX and frosted is almost finished. I must implement the semaphore. But Joel Bodenmann told me that frosted has already implemented the framebuffer support to use graphic functions.

compile frosted with framebuffer support
open "/dev/fb0"
set your RGB palette via ioctl(fd_fb, IOCTL_FB_PUTCMAP, ...);
use write/lseek to fill the framebuffer
