LCDproc 20x2 I2C OLED Character Display with ODROID-C2
I have attached the working hd44780.so to this post to save time and troubleshooting for another person who would like to use this OLED with LCDproc on ODROID-C2 running LibreElec.

1. Jumper BS0 = GND, BS1 = VDD, BS2 = GND on OLED to enable I2C then connect to your ODROID C2 using Wiring Diagram below.
2. Install XMBC LCDproc and LCDproc from Add-ons.
2a. Add-ons > Download > Install from repository > Kodi Add-on repository > Services > XBMC LCDproc
2b. Add-ons > Download > Install from repository > LibreELEC Add-ons > Services > LCDproc
3. Copy the new driver to /storage/.kodi/addons/service.lcdd/lib/lcdproc/
4. Modify ~/.kodi/userdata/addon_data/service.lcdd/LCDd.conf with LCDd.conf below.

40mm 5V fan
ODROID-VU7
5V/6A US Power Supply
ODROID-XU4 clear case
SanDisk 64GB MicroSD system drive
SanDisk 64GB USB drive (for recording small track counts)
USB3.0 to SATA Bridge Board Plus with SanDisk 240GB SSD (for recording large track counts)
Plexiglass sheet
4 x small zip-ties to hold it all together

Software requirements
Ubuntu (ubuntu-16.04.3-4.14-mate-odroid-xu4-20171212)

SuperTuxKart on ODROID-XU4

Karts. Nitro. Action! SuperTuxKart(STK) is a 3D open-source arcade racer with a variety characters, tracks, and modes to play.
SuperTuxKart is a free kart racing game. It focuses on fun and not on realistic kart physics.
Recently, STK developers updated their source code to support the OpenGL-ES 3.x and we can play the nice game on the ODROID-XU4 natively.
Let's try to compile the source code and build it! This instruction was tested on the official Ubuntu 16.04 image version 20171212.
If you are an OGST image user, simply install it with "apt-get install supertuxkart-odroid".

ODROID Arcade Box
ODROIDs have better performance than the competitor boards, especially in video rendering, which means that ODROID boards are very suitable for playing games, which many ODROID users do. There are already several game platform operating systems available, such as Lakka (http://bit.ly/1NO8BBC) and ODROID GameStation Turbo (http://bit.ly/1ASFO5O). In order to enjoy our gaming sessions more, we made our own arcade box with simple GPIO buttons and joysticks, and called it the ODROID Arcade Box. We choose an ODROID-XU4 for this project because it has the best GPU performance of all the current ODROID devices. This article describes how to recreate the ODROID Arcade Box for yourself.

Prospectors, Miners and 49er’s – Part 2: Dual GPU-CPU Mining on the XU4/MC1/HC1/HC2
Last month’s article introduced Dual GPU-CPU mining on the Odroid XU4/MC1/HC1/HC2. This month we’ll update the community on the progress of improvements to the original work and discuss some basic GPU tuning. The removal of all the OpenCL AMD dependencies and INTEL assembler for the OpenCL kernels and crypto algorithms is now complete for sgminer-arm. Genesis Mining also recently released a new version of sgminer-gm 5.5.6. Those changes have been incorporate into the completed newly released sgminer 5.5.6-ARM-RC1. Here is brief summary of the kernels and crypto algorithms that were modified for the Odroid and the test results.

ocl/build_kernel.c
algorithm/cryptonight.c – INTEL assembler optimizations
algorithm/neoscrypt.c – AMD architecture optimizations
kernel/cryptonight.cl – AMD OpenCL extensions
kernel/equihash.cl – AMD OpenCL extensions and AMD architecture optimizations
kernel/ethash.cl – AMD OpenCL extensions
kernel/ethash-genoil.cl – AMD architecture optimizations
kernel/ethash-new.cl – AMD architecture optimizations
kernel/lyra2re.cl – AMD OpenCL extensions
kernel/lyra2rev2.cl – AMD OpenCL extensions
kernel/whirlpoolx.cl – AMD architecture optimizations
kernel/wolf-aes.cl – AMD OpenCL extensions
kernel/wolf-skein.cl – AMD OpenCL extensions

Choices had to be made about specific coin algorithms and OpenCL kernels that had architecture specific setting (not AMD extensions) as indicated. 70% of the OpenCL kernels share one or more of the same AMD OpenCL extensions, that were modified and tested with the cryptonight kernel, which also uses 2 OpenCL helper kernels (wolf-aes.cl and wolf-skein.cl). It appears that ethash-new.cl is not used for any coins which would leave only 2 unproven in anyway, whirlpoolx.cl and ethash-genoil.cl. The others had only AMD and or Nvidia architecture optimizations that were removed. The most conservative approach possible was used in modifications so they would run on a wide range of current and future GPU’s, but there is always room for technical and human error. The sgminer-arm implementation should be CPU and GPU agnostic which raises the possibility for adding some ARM-Mali optimization based on specific architectures (ARMv7, ARMv8, Mali-T628, Mali-T860) in the future.

Tuning the GPU
When first trying to figure out what the settings should be for a coin you haven’t mined, start very conservatively with all of the setting and work your way up using trial and error until it starts to fail or the performance starts to drop. Here are some settings that are a good place to start:

Setting Up Your ODROID: ODROID-XU4 As A General Purpose NAS

I wanted my ODROID-XU4 to do much more than being a plain old NAS. For instance, I plan on transcoding TV shows recorded from my TV to the H264 standard, using the ODROID-XU4’s hardware encoder (as described in http://bit.ly/2jnv4Za), and also make use of the GPIO pins later on. One more issue I had with OpenMediaVault is that it runs on top of Debian, and I wanted to keep using Ubuntu in order to benefit from newer packages.

I would be losing much of the convenience of using a specialized distro and consequently have to discover alternate ways of doing things in a simple and user-friendly way. This presents an opportunity to gain new knowledge.

These are the steps we will need to take:
- Install the mainline kernel Ver. 4.9 (optional)
- Install Webmin (http://bit.ly/J5WtfI) for easier management
- Mount the disks
- Set up network shares (Samba/NFS)
- Install Owncloud
- Secure and optimize the OS
