Please Help: Odroid C2 + VU5 No Touch

Unread postby microamps » Tue Feb 14, 2017 11:08 am

Hi!

I recently got an Odroid C2 and a VU5 touch screen display. I was able to set it to the correct resolution but I can't seem to use the touch input. Just some background on my setup:



1. I'm using a 5V 3000mA power supply to power the Odroid C2
2. This is a new install using the image file: selfinstall-odroidc2-eng-s905_6.0.1_master-15-v1.3 then updated using the Odroid Utility
3. It seems the usb controller is being detected on android (checked with lsusb)



I tried the fix on this thread: http://forum.odroid.com/viewtopic.php?f=137&t=20959&start=50 but I was getting permission denied error when I enter: echo -n 1-1.3.0:1.0 > /sys/bus/usb/drivers/usbhid/unbind

I hope to make this work as quickly possible, any help would be very much appreciated.

The Vu5 touchscreen should work out of the box.

Measure the voltage on 5Volt rail of 40pin header with a DMM.

The voltage must be stable at 4.7~5.2V. Otherwise, the touchscreen controller doesn't work correctly even it is detected as 16B4:0704.

Hi odroid, thanks for the quick reply.

I measured the 5V rail on the GPIO header and I'm reading a stable 5.23V, is this ok? Aside from setting the resolution, are there other settings I need to configure for the touch?

The voltage is fine if you measured it while the LCD display was working.

If you can find "16b4:0704" in "lsusb" output, the touchscreen is detected well.
Type "getevent" on the Terminal app and touch the screen and let me know the result.

I checked the voltage with the VU5 connected and the voltage was stable at 5.03V

I did what you suggested and this is the output:



There's nothing happening when I touch the screen after running getevent. Would this mean that my touch controller is defective?

Please try the latest 5.1 image(self-install) to test your touchscreen.
http://odroid.com/dokuwiki/doku.php?id= ... _note_v3.3

If it still doesn't work, your touchscreen controller might be damaged.
In that case, contact "odroid at hardkernel dot com" with a link of this thread.
She will help your RMA process if you purchased the board from us directly.
Otherwise contact your local distributor. Sorry for the inconvenience caused.

Hi,

I tested the image on the link you provided. The resolution worked at boot but still no touch.

I will now try to RMA it through your reseller here in Melbourne https://jiffyshop.com.au/SBC/

Thanks.
