Scary times in the pcduino world today...

I bought a couple of pcDuino boards a few years ago. These seem to be discontinued and obsolete hardware now, but I'll be buggered if I'm going to throw them away!

I came a little unstuck today trying to use one to run a nodejs service. A while back I blogged that I managed to get node running on the board. Recently I wrote some nodejs module that fetches data from the internet and writes it to the /tmp/ directory on the pcDuino.

I wanted to update the version of nodejs on the pcDuino, so I could use the let keyword (rather than var).

Ended up getting myself down a rabbit hole where I had no working version of node on the device - and ofcourse, couldn't remember how to re-install the old version.

Anyway, here's something I found out that may be useful to other people using obsolete hardware!

Tried to install the latest version of "n" from npm

cd /tmp
npm install n

Didn't use the "-g" option as I didn't want to get myself stuck with an incompatible version of node.

Couldn't install anything as the version of SSL on the pcDuino is obsolete too!

This helped:

npm config set strict-ssl false

NOTE: probably not a good idea to leave this flag set this way!

Sadly the next step really screwed me:

sudo /tmp/node_modules/n/bin/n latest

Luckily I managed to recover using this:

sudo /tmp/node_modules/n/bin/n 5

I think when the newer versions of node try to install they need to compile something, and they require a version of the C++ compiler/libs that aren't available on the pcDuino. I have no idea if I'd be able to build those libs for the pcDuino and I don't want to go down that rabbit hole. But for now, using version 5 of node seems to work!

My node is now reporting version 5.12.0 (rather than 0.10.x)
My npm is reporting 3.8.6

Hopefully this will be good enough to get my stupid project out the door!

node.js on pcDuino

This looks interesting.  Nay, necessary!

Looks like the other primary way to program the pcDuino is to use Python.  A language I have yet to investigate.  Node is a much better choice for me, given the number of hours a week I've spent writing JavaScript.

Peformance may be the one concern.

Intro to pcDuino (video)

As part of my ongoing attempt to archive pcDuino info before it disappears from the internet, here's a pcDuino introductory video. If necessary I'll make a copy and post on my own channel, should the original go down. But for now, SparkFun is the authority on pcDuino it seems...

Well, I was smart enough to buy a pcDuino a couple of years ago.  Then a year or so later I bought a pcDuino v3.  Unfortunately, I wasn't smart enough to try use either of them.  There are only so many projects one can work on in a week!

Just looking around today for documentation on getting started,it looks like pcDuinos have vanished off the planet.

Hopefully I can scrape together enough docs to build something with mine.  At least I found this on Amazon:

Next, I need to decide what to build.
