Rock pi X Touchscreen

#1

Hello all,

I have purchased a 5 in touchscreen and the display feature is working great but I have issues trying to get the touch aspect to work.

Here is a link for the one I purchased: https://www.amazon.com/gp/product/B07NRYPZM1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

I am currently using a rock pi x B 4gb 32 emmc with a fresh version of ubuntu mate 18.04 installed. I have the screen plugged in via hdmi and attached at the GPIO pins. I am still unable to detect the touch screen even after working through the walkthrough at http://www.lcdwiki.com/5inch_HDMI_Display

I cannot run the xinput-calibration and if I try to calibrate from ubuntu settings it says that there is an error and does not detect any calibratable devices.

I did notice when I needed to install the drivers under the arm architecture what are the amd64 options for drivers and is this device compatible with the rock pi x B.

Thank you for any help you can provide!

I just wanted to update this post as I found the solution months ago! It turned out to be a bad usb-Micro power cable which is why the touchscreen function failed to work.

I feel so defeated! Always look for the simplest solutions.

I’m glad you solved the problem. This way, you have confirmed that spi communication works fine. Did you use “logic level converter” during installation.

Fixed my typo it was a usb to usb-Micro cable that was bad. I did not use a “logic level converter” for this build. Thanks again for reaching out.
