Using notes provided by Sam and Malcolm as a springboard…
Download the ADB drivers from clockworkmod.
Grab the GoogleVRForUnity package.
More instructions that I’ve grabbed from a short document that my friends created and shared…I’ll post details if they’re ok with that.
Currently building and will try to launch in Daydream once that is complete.
I may also try the vive as a target if this goes well. The nascent game isn’t really that exciting, but I’d like to get things basically working in all three environments if I can.
Looks as if my Android SDK location is a problem…it is in my users area and the path has a space in it. I’m trying to get android studio to relocate the SDK…currently it is in a hole and not coming out.
I expect to finish the current piece of tool code in C++ and then look at wrapping it (or perhaps a C++/CLI equivalent) in a WPF/C# UI tool for managing file duplication/archiving. Depending on how things go I might play with some ASP.NET Core/Angular code on this front too but not sure at the moment. I need to get a better handle on my current sprawl of archival storage without losing anything that matters.
Reading through Effective Java Third Edition and re-reading Effective Modern C++ (with some digressions into The C++ Standard Library Second Edition).
I’ve been looking at low level communications interfaces for microcontrollers for a while. Things like SPI and I2C seem limiting as operating voltage levels vary (at least 3.3v and 5v) and for SPI fan out is clunky/limited.
I’ve had several people whose opinion I respect say good things about CAN. It seems to be predominantly an automotive standard but the interface parts seem to be cheap enough and the interface more than flexible enough to work for general embedded projects. It runs at 5v on the physical layer and the controllers appear to be voltage flexible so that is a big plus.
A quick search turned up some microchip interface components and they have DIP versions so they’d be easy enough to use in a prototype environment.
The MCP2515 (datasheet) appears to be a reasonably priced SPI to CAN controller that would likely work nicely with either an RPi or AV controller (as in an arduino). Mouser has then for $1.88 for singles and $18..50 for ten so pretty reasonably priced.
The MCP2561 (datasheet) seems to be the physical layer companion part, also available in DIP packaging and DigiKey has these for $0.93 each or $19.31 for 25.
I’ll likely do some more reading tonight. Once I get my workbench in the basement cleared and ready for use, I’ll likely buy a few of each of these and see what I can do with them.
PC/USB to CAN interfaces seem harder to come by. Most of what I saw online are $100.00 and up diagnostic probes. Useful items for development, but very expensive is all you want to do is talk to a device. I did find one break-out board from a side called tindie that seems to offer a $25.00 solution for the basics. Still seems a bit expensive and suggests putting together something ad-hoc with an AVR board and a controller/phy. As an initial, easy to use bootstrapping solution it looks potentially interesting though.
I’ve found the various Effective C++ books (and the broader ‘effective’ series in general) to be a useful resource for brushing up on the finer points of best practices. They cover the details that a professional developer needs to understand and skip the language learning bits.

I’m building the latest release of g++ to play with. It probably isn’t necessary as the 7.3.0 version that is currently in stock cygwin (and something close in Ubuntu) covers most of the interesting c++ 2011 and 2014 ground. I expect g++ 8.x.x. to add in more c++ 2017 features.
I’ve been a bit focused on C# and Java of late and I’m planning on knocking the rust off of my c++ over the next few months. Not sure exactly what I’m going to sandbox, but there are plenty of options…
Decluttering and pulling some unneeded pieces of furniture as part of an overall clean-up. We’ve lived here since our daughter was young and the time has come to simplify a bit. Taking a table and display rack out and rearranging what is left.
Continue reading Almost done with my home office simplification…
Well…last week was pretty unpleasant all around. I’m expecting the coming week to shape up better. The craziness is settling down and I’m getting things squared away to get some more sandbox coding done on the home front.
Just got my RPis updated, located g++ 8.x for the RPi. Linux NUC is good to go. Still lots of work to get the basement squared away, but that has needed work for some time and projects will be easier to push forward with the downstairs work-bench easily accessible.
Malcolm has offered plastics to complete the RepRap 3D Printer that I’ve had some of the parts for sitting around for years. The HTC Vive is still waiting for some OpenGL code to do interesting things. Plenty to get to…
Getting my Linux systems updated to current versions and pulling a C++ 2014/2017 capable g++ in.
May wind up re-imaging some of the RPi boards. Need to dig up the arduino/AVR boards. Moving forwards to get some more interesting embedded sandbox things going.
That looks better…the red RPi wasn’t associating with the non-guest WiFi…apt update going now. Convenient having the no-password guest WiFi SSID…I’d recommend UniFi enterprise APs to anyone with an area too big for a single AP footprint…decent price, good features and relatively easy setup.
The landing page theme I’m currently using displays nothing but a large image, the blog name and a (rather skimpy) arrow down to content.
I’m afraid that this is likely less functional than I’d prefer…it would be pretty easy to drop in here and miss the actual contents of the page and thus all of the links to ‘real’ content.
I’m going to take a look at available free themes and see if I can find something that meets my needs better. I’d be willing to pay a one-time fee for a theme that did a great job, but I’m not convinced that I’ll find one readily.
I am likely to start digging into PHP and WordPress theme creation sometime soon to see is I can modify one of the stock themes to get the job done. I’m not certain that I’ll be willing to spend the required level of effort at this time, but it is worth some initial investigation.
C++ has been my go-to language for most of my career. I haven’t written any significant amount of C++ code in a couple of years though so now is likely a good time to circle back in the sandbox at home. Not sure what I’ll write, but I’m sure I’ll find something.
Still trying to deal with a bunch of house stuff at the same time so this is likely to be slow going in the near term…
