[Resolved]PiScreen not displaying anything

[raghavsood]

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 connected

Can please show me the output of these commands

dmesg
ls -l /dev/input/event*
cat /proc/bus/input/devices

Hi Mark,

Here are the outputs you asked for:

dmesg
ls
cat

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?

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.

OK… that looks faulty. Sorry about that.

I will send you out another one today.
