I'm trying to port the ODROID 16x2 LCD kit to the Rock64. The LCD functions with GPIO pins. However, since GPIO on the ODROID and the Rock64 differ, I'm trying to port the pin system. The GPIO shield for the ODROID LCD is unnecessary for porting this since the P2 block on the LCD board itself has its own pin scheme. There are only 16 pins in this scheme (of which only 10 are used). See pictures below for layout details...

The P2 block on the LCD shield. This block directly powers the LCD. GPIO input shield is a different set of pins.




The entire shield (notice the stacked boards). The pins on the green board directly control the LCD. The pin input information for the 16 pins on the green board are in the above image. "X" indicates the pin serves no purpose.


Would this involve modifying the code for the ODROID LCD controller program? The code and installation instructions for the ODROID-C (I assume any C model ODROID board) can be found here (https://wiki.odroid.com/accessory/displa...ld/c/start).

I'm new to GPIO so any clarification regarding my understanding of the pin system are appreciated.


Thanks.

Hi!
I'm using SSHDroid SSH Server app to enable SSH access to my Rock64 board, but what ever setting I check in app it fails to start at device startup. Does anyone has idea how to fix this problem?

i use my pine a64 as a media player to stream services like netflix,...

to be able to run the netflix app, i have android 7.0 running.

after power-up, my pine takes quite a long time to get ready for operation.
is there a way to speed up the boot process?
is there a better os than android to use the pine for streaming?
is there anything else i can do to improve performance?

thanx for your help!

Hi All,

 I purchased the original Pine Board along with Pine's 64GB Micro SD Card, the battery and the display. I waited a very long time for the back-ordered White Pine Box and finally received it and set it aside. I recently started to assemble it and used the Pine (Etcher) software to download and flash the Android 6.1 OS that's supposed to be compatible with the touchscreen. It took a couple of attempts but I was able to flash the OS and put the card in the board.  When I Powered it up nothing happens but a red LED lights inside the box.

Any Ideas??

Any help is appreciated, Thank you,

Tom

I am new to the ROCK64 and want to put a 16x2 LCD screen on it to display statuses.  Has anyone used one that they can send me a link to for purchase or have any hints on one that may work?

Thanks in advance!

Hello, this is my first Forum post, so correct me if I do anything wrong, anyway:

I've purchased a Rock64, when it's delivered, I want to power it by battery (Power bank), yet I want the read the battery state. My Idea was to connect the Rock64 via USB right to the Power bank (as usual), but an additional cable directly from the 3,6V battery to a GPIO pin and read it using software.

I have no idea about GPIOs, so is it totally wrong, could it maybe bridge the undervoltage protection and therefore bring me into trouble, or can this actually work?

Another idea of mine would be to connect + and - of the 4 status LED's and provide its on/off state to the GPIO and then determine if the battery is at 100-75, 75-50 25-50 or 25-0% charge.

What is the best approach to get battery levels to a Rock64?

Just got my pinebook two days ago.To get my feet wet with modding I decided to start small and do a simple case mod. I have access to a laser cutter at work, so I tried engraving a light pattern on the lid. There were a few problems with alignment but I think it turned out pretty neat.


Next up I would like to design a replacement for the small companion pcb in the pinebook. The plan is to keep the original functionality while adding a small FPGA either a Spartan 3A or an ice40. This way I can have some fast reconfigurable IOs with a USB bus to the SOC. Does anyone know if the layout for a small board is available somewhere?

Hi All,
 I'm a newbie and can use some help. Are there any on/off or reset switches for Playbox Enclosure Case?
 I got a little note saying a on/off switch was sent as a bonus but I can't find it, and I don't know how I would be able to do anything.

  What I ordered along with the board was the 7inch touchscreen and the lithium battery. The battery seems to be charging when I plug it's charger in (at least a red LED can be seen inside the case, but it stays on even after I unplug the charger).

 I need to solve how I'll be able to turn this off and on.  (I'll deal with installing OS next )

Any help is appreciated.

Thank you.....Tom
