Hi!
I have to move from SDL1.x to 2.0 because rapid keystrokes (e.g. automatically generated ones) won't work with 1.x branch for linux/Xorg. Since the target is a raspberry pi (2), I can't use X anymore with 2.0 branch, which means the events have to be fetched using evdev directly. Problem is: the udev code only selects ID_INPUT_KEYBOARD and ID_INPUT_MOUSE but neither ID_INPUT_TOUCHSCREEN nor ID_INPUT_KEY (so touch events (ABS) from a keyboard would work but not from a touch screen). Where ID_INPUT_TOUCHSCREEN is obvious and ID_INPUT_KEY would be for GPIOs mapped into userspace (e.g. gpio-keys module). Is there any chance that the file's author/maintainer might have time to fix this? Btw. is there any chance that the performance regression using X on raspberry will be fixed? Rendering to a "texture" (uint32_t*) and presenting it using the xorg driver results in 0.5 FPS. The very same code rendering (directly) to an SDL_Surface and flipping it ran with 20FPS (SW Limit) at <10% Load for SDL1.2 when only flipping or >10FPS (at ~100%) when completely redrawing it. I'd love to use X, because the "box" will also run X anyway (for other programs) and allowing to use a/the same Xorg.conf for both programs would be nice. Best regards and thanks for the great project Andreas Lausch _______________________________________________ SDL mailing list http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org |
