I received my kickstarter pledge and assembled the PiScreen today.
After connecting to it, I can't seem to display either the test image, or the console on it.
The backlight works both in hardware and software. I can see the device in /dev/fb1 and /dev/input/event0, as well as /proc/bus/input/devices
Neither the evtest or ts_bin tests show any form of touch input, even though I can see a mouse in my hardware listing, despite having no USB mice connectedOctober 18, 2014 at 5:02 pm #2802
Can please show me the output of these commands
dmesg ls -l /dev/input/event* cat /proc/bus/input/devicesOctober 19, 2014 at 4:18 pm #2804October 19, 2014 at 5:43 pm #2806
Everything in that output looks correct.
One last question.
When starting X Windows, Does the touchscreen work with the calibration program that runs just before X Windows?October 19, 2014 at 11:35 pm #2818
The touchscreen shows no images and sends no touch events whatsoever.
Even after setting it to display the console, and when trying to display the test logo image, I can see nothing on the screen.
Neither the calibration program, nor evtest can receive any touch events from the screen.
I have a feeling that the screen unit itself is defective, as even when the backlight is on, I need to push the screen up from its bottom edge before the light actually comes on, as shown in this video I took.October 20, 2014 at 12:28 pm #2822
OK... that looks faulty. Sorry about that.
I will send you out another one today.October 20, 2014 at 2:18 pm #2824
Thank you! Appreciate the service
