  1. The Banana Pi M3 has a totally different SoC / CPU and GPIO register layout to the Raspberry Pi's. You can't use that library with the Banana Pi M3, the RPI library is coded specifically for the SoCs on the RPi's.
  2. Refer to this C library: https://github.com/luoyi/h3-gpio which seems quite fast, and read this comment. It appears 10Mhz should be doable, but only if you do not read the value of the GPIO. So cache the latest value of the GPIOs locally in your code as a local variable if say, you need to do bit manipulation.
  3. A very hackish port exists of this Raspberry PI RGB LED Matrix Library which works for Allwinner H3 devices. This works by bit-banging 14 GPIO pins simultaneously to achieve about a 10Mhz throughput / 100fps refresh rate. Refer to here: https://github.com/mrfaptastic/opi-allwinner-h3-rgb-led-matrix I managed to easily get up and running using an Orange PI. Refer to the README of the github repository.
  4. Update, for whatever reason this is broken in Armbian focal, and the issue appears to be due to an Armbian shell script that xrdp doesn't like, so after doing the install, you also need to then do: sudo mv /etc/profile.d/armbian-check-first-login.sh /etc/profile.d/armbian-check-first-login.old And volia, you'll actually get a desktop when you RDP from windows.
  5. Hi Jernej, are you able to elaborate on the h265 compile flags that should be set?
  6. Hi, There have been a couple of posts about this over time, but I was wondeing if somebody could please provide concrete example / sample code that uses DMA to TX out the GPIO pin(s)? I want to be able to TX outwards only from my Allwinner H3 device (Orange PI PC) to 16 pins in parallel (so 16 bit DMA in parallel) from a chunk of memory in RAM. Happy with a basic example if somebody has which just blasts out one GPIO pin even.
  7. Hi, There's been a few guides around on how to get RDP working with Armbian so you can login from your Windows or other PC. Some solutions mentioned in various threads here were: Install tightvncserver instead + x2go bloat (i.e. use VNC) Only login as root - didn't seem to make any difference for me Change some permissions of a log file in your home directory. Well, this is what I did on my Orange PI PC running Buster desktop with Kernel 5.4, as of April 2020. sudo apt install xrdp xorgxrdp sudo systemctl enable xrdp sudo reboot ...
  8. OK. I'll refer to the Git going forward. My question was more out of curiosity, not a demand. Armbian on an Orange Pi PC does everything one could want now thanks to the work sunxi have done and your tireless unpaid hard work. It's amazing how far things have come. Merry Christmas!
  9. Hi Igor. Is there any update on mali integration in the mainline kernel? It does not look like there has been any movement on that pull request, so I assume hardware accelerated 3D graphics is still out of the question?
  10. Hi, I installed Armbian Buster Desktop last night (finally upgraded from the legacy 3.X Jessie distribution) for my Orange PI PC and HDMI Audio worked fine. Just needed to select this option in the Audio Config. Pity about the fact there's no hardware accelerated video etc... but hopefully by 2021 we might have that working in the Linux kernal!
  11. Yep. The Orange Pi's are total garbage. All they really are is a Chinese TV box without a case! Might as well buy a TV box!
  12. Requirements: Doesn't require endless stuffing around to get working with various Kernel patches. Not a headless device. Want to be able to plug this into HDMI to view a basic desktop. Linux Kernel o f > 4.6 support + future compatability. (i.e. my orange pi is basically stuck forever at 3.0 unless I want a headless box) SSH / Web Server NAS of USB attached devices Desktop Web Browsing with decent video playing performance Video playing of H265 and 264 output. Audio playing support of course (2 channel sterio is OK) Bonus points: Hardwa
  13. https://www.raspberrypi.org/blog/raspberry-pi-4-on-sale-now-from-35/ I'd be interested to know if it still uses the same binary blob VPU to boot from. Interested in your thoughts, especially tkaiser :-)
  14. Hi, Long time OrangePi PC user here who was going to get another of these devices but is intrigued by the TV Boxes which some can be get for about $15. I'm confused about what is the 'best' Tv Box chip-set to get here, Amlogic (yeah I noticed the threads about them lying about CPU speed, but I don't care) or Rockchip etc. What has the best, or is likely in the future to have good Linux Kernel support for WiFi, Ethernet, SD Card, Audio, HDMI and Hardware Decoding (and bonus points for encoding!)? Amlogic seems to be a winner right? Any links to A
  15. Hello! I bought an Orange Pi PC about two years ago which is still working perfectly to this day (very happy with it), but I am curious to know what would be considered the 'best' Single Board Computer at this time point time, which would be around the same price range ($15 USD). 'Best' being defined as having a decent processor, and good software support - which the Orange Pi PC eventually did. I'm tempted to just buy another one of these for another project, but interested to know. Again, the main factor is price - $15 USD or less would be ideal.
