Vocore has arrived

My tiny Vocore Linux machine has arrived from China. Cool! So far all I have not done much more than boot it up and check that I can log in and stuff. Oh, and I tried the web-based interface too. It seems to be working fine. A Linux box about the size of a postage stamp, what’s not to like?

Mine has the dock attached to it, so I’m just using a USB cable to power the device. I tried to power it off a USB socket on my MacBook … but there wasn’t enough current to allow the wifi to start. Some lights flashed on the Vocore initially, but then it went off a few seconds later. I think that this means that there is not enough current to allow the wifi to start operating… But when I ran it of a dedicated USB power supply it was fine.

Because I have the dock, I used an ethernet cable to connect to the Vocore, which means my laptop can remain connected to my home wifi and I can still use the Vocore with its default settings.

But when sitting in front of the command prompt I got as far as making some LEDs go on and off with commands like these:

echo 255 > /sys/devices/gpio-leds.5/leds/vocore:green:status/brightness
echo 0 > /sys/devices/gpio-leds.5/leds/vocore:green:status/brightness

The advantage of doing that is that they use an LED which has already been connected up on the dock … so I didn’t need to wire anything up. I’m going to try the same thing in a little C program next. Blinking an LED is an ideal little test program

The next thing that I’ll do is try my own minimal webserver, which might be useful if I start running out of space. So that’s next on my agenda.

Apart from that, I’m not really sure what I’m going to use it for. I’m sure I’ll think of something...
