Hi,
I bought a Pine64+ (allwinner A64) board and screen, knowing that this was not yet supported. The reasoning being that it is cheap and ticks a lot of the hardware boxes for a Squeezebox touch replacement with dedicated ethernet and USB ports/busses.
Armbian runs out of the box and supports the touchscreen (at least with legacy 3.10.104 kernel).
There is a are-compiled squeezelite in the Armbian repository and Jivelite compiles and runs without errors using
https://github.com/sindrom91/LuaJIT/tree/ARM64
Athough touch events work perfectly in Xfce, they are "all over the place" in Jivelite, so I'm trying to create a tslib/SDL calibration.
Just now I'm struggling with
"tslib: Selected device is not a touchscreen (must support ABS and KEY event types)"
Googling throws up one or two bits of advice, such as:
From http://http://www.cubieforums.com/in...,prev.html#new:
Check if input-raw.c has:
if ((ioctl(ts->fd, EVIOCGBIT(EV_ABS, sizeof(absbit)), absbit)) < 0 ||
!(absbit[BIT_WORD(ABS_X)] & BIT_MASK(ABS_X)) ||
!(absbit[BIT_WORD(ABS_Y)] & BIT_MASK(ABS_Y))) {
/*fprintf(stderr, "tslib: Selected device is not a touchscreen (must support ABS_X and ABS_Y events)\n");
return -1;*/
}
if not, edit the file and comment the lines."
and
from http://stackoverflow.com/questions/1...nnot-calibrate:
Try to add
input_dev = input_allocate_device();
[..]
set_bit(EV_ABS, input_dev->evbit);
set_bit(EV_KEY, input_dev->evbit);
So that the tslib sees the device as supporting both EV_ABS and EV_KEY events (even if it does not actually send both of those).
(I'm assuming this should also be in input-raw.c)
If I look at my own input-raw.c, I see:
and I can't see why the test is failing as
Can anyone point me in the right direction to getting the device calibrated?
I figure that if I (with help) can get this working, it might be an excellent and cheap squeezebox touch alternative.
