Hi Robert,
That appears to work.
With the 4.4.91-ti-r133 kernel I had to do this to run the libts-bin
utilities:
$ sudo TSLIB_TSDEVICE=/dev/input/event2 ts_calibrate
$ sudo TSLIB_TSDEVICE=/dev/input/event2 ts_test
With the 4.4.91-ti-r141.1 kernel the utilities now work with just:
$ sudo ts_calibrate
$ sudo ts_test
Thanks!
Unfortunately, this didn't fix the problems I see with SDL1.2 and pygame.
It appears the 1.2.15+dfsg1-4 version of libsdl1.2debian has support for
tslib
removed since that package is not available in the "normal" jessie repos.
It looks like you are providing tslib from you repos:
$ dpkg -l | grep libts
ii libts-bin 1.14-1rcnee0~stretch+20171122
armhf touch screen library utilities
ii libts0:armhf 1.14-1rcnee0~stretch+20171122
armhf touch screen library
Any chance you could provide a libsdl1.2debian package that works with
tslib?
I can go back to a wheezy image but I would rather use a newer one.
Thanks,
Hartley
