[eGalax Touch Screen Orange Pi One]

Setup:

 

• Orange Pi One
• 16Gb SD card
• Running Armbian Stretch (Mainline Kernel 4.14)
• Using XFCE4 Desktop Environment
• eGalax Touch based 1503M 15 Inch 1024*768 Monitor
• HDMI (IN - FROM Pi) to VGA (OUT - TO MONITOR) Adaptor

 

I have the monitor setup and working, everything boots through to XFCE however the touch panel is inverted and the 'active area' is smaller than the screen.

 

Although the touch panel is responding I have the following issues

 

• X and Y crossed over
• Both Axis Inverted
• roughly 2cm 'Dead Zone' on the perimiter of the screen

 

I have attached it to my laptop and the screen works fine, so It must be a driver issue.

 

Ive tried to use xinput_calibrator and save the output to 99-calibration.conf in /etc... however it makes no difference

 

How can I go about getting this screen to function correctly?

 

Ive tried the drivers here however the installer reports that the detected controller is not HID compliant

 

Any help appreciated,

 

Andy

[pyA20 Orange Pi One (H3)]

I'm trying to access GPIO through python using the following library: https://github.com/duxingkei33/orangepi_PC_gpio_pyH3

 

Online guides say that for OPi One this should be a plug and play solution. However, for me, the pins dont seem to be mapping properly, running dir(ports) and dir(connector)

yields the results shown here All the PAx pins are missing, and the results bare no similarity to the actual pin config found here

 

any help appreciated,

[Developing GUI Apps - Qt]

Hi all, thanks for the comments on here,

 

by far the easiest way Ive found to develop a GUI app is to use electron

 

There is a pre-compiled version for arm with support for H3 and mali 400

 

thanks for @Sodrohu for suggesting it,

[Vanilla install hang at starting version 232]

Im using armbian stretch on an Orange Pi Zero Plus. On normal boot up, the system hangs at starting version 232 for around 1-2 minutes. After this the system procedes to boot normally.

 

What is this delay time and is there any way I can remove it?

I am trying to build Qt on an Orange Pi One by following the guide here: here

 

It says that

Before we begin please make sure that you have a working cross-compiling toolchain. This will either be supplied with your device's SDK or you can build your own.

 

How could I go about obtaining or creating the toolchain for the Orange Pi One (Running Armbian Xenial)

You should use either NW.js or Electron.  They're basically Desktop apps that run using the Google Chrome engine. So, like a web page that you can open from the desktop. I use NW.JS for work so I can vouch for it myself,  but I dunno about Electron since I've never used it extensively (even though it seems a lot more popular).

 

Both of them uses node.js and codes in Javascript. So if your background is in front-end website development, this will be easy to start up.

Could you take me through how you've got NWjs to work on the orange pi?

 

Thanks,

Ill certainly look into those, the only problem is that I need to be able to control the hardware too as this system is effectively used to turn relays on and off which is what made me stick to C/C++/Python

Hi Tido,

 

Thanks for your reply, I have had a search for kiosk but in my case that is irrelevant as the problem is just developing a GUI application for Armbian, it just so happens the intended use is a kiosk style system,

 

Where can I find the documentation for compiling and is that compiling related to Qt5?

 

Thanks,

 

Andy

[Developing GUI Apps - Qt]

I'm trying to develop a kiosk system using an Orange Pi One (Based on Allwinner H3 - Mali400) running Armbian Xenial

 

To do this I need to develop a full-screen GUI application (I don't have much experience in this area)

 

I'm looking for a professional way to do this, Ive spent about a week trying to get Qt to cross-compile from my laptop but not getting much luck,

 

Any ideas / advice welcome,

 

Andy

Im in the progress of making an internet radio with an Orange Pi Zero plus using armbian.

 

Ive just gone to enable the audio device in armbian-config and when i go though to system -> hardware, the list is completely blank with just tick boxes but no content

 

Any ideas?

[Orange Pi Zero Plus (V1) GPIO]

Just managed to find this with an updated mapping for H5

Thanks for the reply,

 

I origionally stayed away from armbianIO as I was unable to switch between input and output during the running of my python program

[Orange Pi Zero Plus (V1) GPIO]

I'm using the Orange Pi Zero Plus for a WiFi radio application and need to operate some LED's / Pots etc

Ive previously used an Orange Pi Zero (Regular) and had no problem using pyA20 library or wiringpi

With the Pi Zero Plus, using pyA20 gives me this error for any port:

AttributeError: module 'pyA20.gpio.port' has no attribute 'PA0'

or using wiringpi (gpio readall) gives me:

Oops: Unable to determine board revision from /proc/cpuinfo
-> No "Hardware" line
->  You'd best google the error to find out why.

Any suggestions appreciated,

Thanks
