Rather than try to code the JNI by hand I used HawtJNI to generate the JNI wrappers. I also used some custom code to generate the HawtJNI methods and font constants. This makes life easier going forawrd as changes are simple to keep in sync.

Code:
final var u8g2 = U8g2.initU8g2();

// Change this to your actual display

        getDrawColor(u8g2)));

U8g2.setPowerSave(u8g2, 0);

Rather than try to build this from scratch I used c-periphery and HawtJNI to generate the JNI wrappers. This saves a lot of hand coding and allows for easier synchronization with c-periphery changes moving forward.

I believe this is the only userspace IO library that supports the new JDK 17 LTS (and still supports JDK 11). I had to fork HawtJNI to make it work with JDK 17. The only caveat is that ARM32 supports JDK 11. For some reason I cannot find a JDK 17 for ARM32 or information on why is was not supported. The install script handles this automatically. ARM64/x86/x86_64 uses JDK 17.]]> Java Periphery is a high performance library for GPIO, LED, PWM, SPI, I2C, MMIO and Serial peripheral I/O interface access in userspace Linux.

I am looking to use the Pine64 as the ‘brains’ to make a ‘dumb’ speaker ‘smart’.

I have limited coding skills so I want to use proprietary software and hardware to do this.

The theory I have is to use an inexpensive Bluetooth speaker with built in mic (like this one: Bluetooth Speaker) pair it via BT with Pine64 and then use the google assistant app from Play store.

Any reason why this might not work? Anybody tried this already?]]>

I just hoped someone can point me in the right direction please? I'd like to experiment with getting a couple of linux distros running on my Pine A64 which dont have any official images, are there any instructions available on how to build an image for this? I have 1 of tge original boards from the kickstarter campaign if this matters. I thought if there are any steps that need to be taken and things I should know then I can apply the build process to diffeent distros I use to see what I can get working well on my Pine.

Any advice would be greatly appreciated.

Many Thanks]]>

First time posting on this forum and completely new to single-board computing.

I have a lot of time on my hands due to college and work being cancelled due to COVID-19, so I ordered myself a PINE A64+ 2GB and it should arrive soon. Very excited to start messing around with it.

My intentions for this board are

>Initially use it as a chip flasher to flash coreboot onto the BIOS chip of my Thinkpad. All of the tutorials I have seen call for a Raspberry Pi but I don't see why the PINE64 shouldn't be able to do the job. Maybe I will write a tutorial if it goes well!

>I live in a collective house. I would like to turn this device into an internet-connected Nextcloud server that I could give an account to each of my housemates if they want it.

>I will also like to set up an instance of Mastodon for the users in the house.

I do wonder if I'm asking too much of this board, for it to be a Nextcloud server and Mastodon server at the same time? What do you think?

I'll let everyone know how I get on.]]>

The drive won't ever be accessed that often, it just seems like a better solution with more access that just having inside a PC.

So, my current thinking is to get a PINE64, probably the 2GB verison, a decent SD card, install openmedia vault, attach the drive to the board and connect the board to my wifi router.

Does this sound like a good plan?

Here is the current project i'm working on, I'm looking into redesigning these cases for the Pine H64 vB to serve the same purpose.
https://imgur.com/gallery/94BSP7J
https://www.thingiverse.com/thing:3711469

The current software side consists of GUIslice as the touchscreen interface, with omxplayer sending video to the hdmi screen. I've been using the videocore layering abilities to overlay dynamically generated png images over the video as well. The buttons are configured for scoring points and busts during video replay, additionally for touchscreen interface navigation when not playing video.

I'm not sure what comparable touchscreen I should look into, as I can modify this design to fit just about anything., the 3.5" screen size seems to be a good overall size for this device. I have lots to learn in the pine64 community and will be updating this thread as my project progresses.

Appreciate any advice and constructive criticism from the community. Thanks!]]>

It's very simple challenge. just sending a signal out and look for it in the input.

But I did then got a good idea:

Why not add a Nextcloud server to my project ?

I found a guideline at nextcloud.com and after an hour or two was my own private cloud up and running.

server.JPG (Size: 236.97 KB / Downloads: 1111)

It has been very stable and fast for two weeks now, I'm using it daily for sharing files.

But It's recommended to have fixed IP address and a domain name to your server, and naturally some open ports at your router (port 445 as far as I remember)
