[Coco] Sailfish

[Rietveld Rietveld]

There was a very cool project on hackaday where they put sailPI (sailfish) on a PI2 and used a touch screen to make a 7inch Raspberry  PI tablet.

Oh, as do I, debian jessie, built for the armhf.

Interestink. The major problem in the rt-pre-empt kernels needed to run
linuxcnc, is the total lack of local keyboard buffering, which because
all the non-gpio i/o is funneled thru an internal usb-2 hub, can get
busy and throw away keyboard events, which if the missed event is a key
up, as you were manually using the arrow keys to move the machine,
leaves it running in the last direction forever until you notice it and
hit another key to stop it.  That same effect is present when attempting
to edit gcode.  So I am watching the pine/rock64 forum for any
showstopper stuff and about to buy a couple of the 2Gb of ram versions.

Unfortunately the only touch screen I still have is being used on my cc3,
but its not high enough resolution to run linuxcnc real well, even a
1366x768 screen cramps its style, much better on a 1920P screen which
the pi drives slowly, about 3 frames a second.  The dual mali gfx  of
the rock64 should do that much faster if that chipset has linux support,
yet TBD.
