Touchscreen input on X2 vs U2 (2013/05/23)
- フレームバッファは3つある
- 0 is the LCD Kit framebuffer
- 6 is the HDMI Framebuffer
- 1 (or something else that I can't remember) is the Fake_fb.
- When no boot.scr is present it will choose 720p 60hz. That's the default screen resolution.
- For further reading and better understanding of that:
- drivers/video/samsung/fake_fb.c
- drivers/media/video/samsung/tvout (hdmi driver)
- those last 4 files are touch-screen drivers from us:
- drivers/input/touchscreen/touch-sysfs.c
- drivers/input/touchscreen/odroidq-touch.c
- drivers/input/touchscreen/touch-i2c.c
- drivers/input/touchscreen/touch.c
メモ
- Normally we made a tricky code in the device driver when we used eGalax touch device driver.
