Unable to combine all dtoverlay parameters #97

Closed tswonke closed 4 years ago

tswonke commented 4 years ago

Describe the bug

I'm not able to combine the commands like this. The last one seems not to be respected (already tried first -y and then -x)

dtoverlay=hyperpixel4,touchscreen-swapped-x-y,touchscreen-inverted-x,touchscreen-inverted-y

To Reproduce

First I used the one-line-installer, but I had troubles to rotate the touch. Then I found the parameters on https://github.com/pimoroni/hyperpixel4/tree/pi3 and was very hopeful, but I don't get it work completely.

My intend ist very simple: Use Hyperpixel4 rectangular in normal or inverted orientation (in any case portrait mode) on an RPI 3A+ with chromium-browser but without desktop. (I have a working setup with the same screen on a Raspberry Pi Zero WH, but with desktop and and older OS).

Without modifying dtoverlay it will be like this:

Swipe → : Cursor ↑ Swipe ↑: Cursor →

dtoverlay=hyperpixel4,touchscreen-swapped-x-y:

Swipe →: Cursor ← Swipe ↑: Cursor ↓

dtoverlay=hyperpixel4,touchscreen-swapped-x-y,touchscreen-inverted-x,touchscreen-inverted-y:

Swipe →: Cursor → Swipe ↑: Cursor ↓

dtoverlay=hyperpixel4,touchscreen-swapped-x-y,touchscreen-inverted-y,touchscreen-inverted-x:

Swipe →: Cursor ← Swipe ↑: Cursor ↑

I don't get all parameters running at the same time, but that is what I need... 😢 Am I missing something? I don't mind installing an older OS version if that helps...

Your HyperPixel 4

  1. Rectangular
  2. Touch
  3. 2019
  4. Directly installed (GPIO)

Your Raspberry Pi

  1. Raspberry 3 A+, Revision : 9020e0
  2. Raspbian GNU/Linux 10 (buster), 5.4.51-v7+
  3. Fresh setup + xinit/xserver + chromium-browser

Extra debugging information

[ 7.537595] Goodix-TS 11-005d: 11-005d supply AVDD28 not found, using dummy regulator [ 7.537693] Goodix-TS 11-005d: 11-005d supply VDDIO not found, using dummy regulator [ 7.539584] Goodix-TS 11-005d: ID 911, version: 1060 [ 7.560093] input: Goodix Capacitive TouchScreen as /devices/platform/i2c@0/i2c-11/11-005d/input/input0

And check i2c is working:

ls /dev/i2c-*

ls: cannot access '/dev/i2c-*': No such file or directory

Is this an issue in my case?

It's highly possible you're exceeding some line-length limit in /boot/config.txt. There's an 80 character limit to any one line in config.txt, and your line is 91 characters.

You should try (if I recall correctly):

dtoverlay=hyperpixel4
dtparam=touchscreen-swapped-x-y
dtparam=touchscreen-inverted-x
dtparam=touchscreen-inverted-y

Wow, didn't know about a limit... This indeed helped!

Thank you very much! 👍
