Setting axis in the firmware? #7

Closed sigboe closed 8 years ago

sigboe commented 8 years ago

So I think I figured out the resolution of my touch screen to be 1700x1125. Or at least if I start with a fresh boot with display settings clockwise, load a firmware with -w 1700 and -h 1125 it tracks 1:1 but one of the axis is reversed. Is there a way to specify this in the firmware?

Yes, in fact there is. Use fwtool to set the xflip or yflip flag. The feature is still untested, though.

That's great, gonna try this today. Might I suggest you rename them to -wflip and -hflip to be consistent with -w and -h

onitake commented 8 years ago

Ok. Sounds good, but I'm just going to change that in fwtool, not the driver.

If the calibration is wrong, it's not that big a deal to redo it, I think. :) Optimally, one shouldn't have to do any calibration at all.

On second thought, hflip is ambiguous. It could be interpreted as 'horizontal' flip.

I'll keep the parameters as they are, perhaps with some clarifications in the help text and readme. I could turn the various -f arguments into standalone parameters, but one-letter options are better IMHO.
