Did I just Brick it??!?
In my quest to get an LED blinking using the Sparkfun GPIO Block (link here), I ran some example code (link here) in eclipse.
And let's just say I didn't use a resistor with my LED...hey it's just one LED right?
Well the blinking didn't occur the way I was expecting... but then again the pin numbering is a bit confusing.
I'll Paste the full pin numbering at the end of this post.
Long story short (no pun intended), I can no longer ping the Edison at the assigned static IP address.
What am I to do? Well I eventually went to the Serial Fall back, which was the first way I was able to ssh into the Edison.
How I did that:
1) With a micro-usb cable connected to the "console" port on the Sparkfun GPIO Block connected to my computer.
2) Went into Device Manager on my PC, then expanded "Ports" and read the COM# of the "USB Serial Port"... you'll know its the correct one for the Edison becasue it wont be present when the Edison isn't plugged in. Screen shot:
3) Fire up the application putty... if you don't already have it you can download it here
4) Select the "Serial" option, type COM# where # is the number you read from Device Manager->Ports
5) Change the Baud rate to 115200 from the default of 9600. Screen shot:
6) When that's all set, click "Open". You should be greeted with a login screen:
----------------------------------------------------------------------------------------------
Ok so I didn't brick it... That's a good thing.Why can't I see it on the network anymore??
It seems the IP address changed from what I had set as static previously, and its in an IP scheme that wont work on my LAN.
But why did the IP address change? According to the "/etc/wpa_supplicant/wpa_cli-actions.sh" file, the reason it's got this new funky IP is:
if [ "$CMD" = "P2P-GROUP-STARTED" ]; then
GIFNAME=$3
if [ "$4" = "GO" ]; then
kill_daemon udhcpc /var/run/udhcpc-$GIFNAME.pid
ifconfig $GIFNAME 192.168.42.1 up
cp /etc/wpa_supplicant/udhcpd-p2p.conf /etc/wpa_supplicant/udhcpd-p2p-i$
sed -i "s/INTERFACE/$GIFNAME/" /etc/wpa_supplicant/udhcpd-p2p-itf.conf
udhcpd /etc/wpa_supplicant/udhcpd-p2p-itf.conf
fi
... So unless I fried it and made it do something strange... It seems I've switched the WiFi mode to P2P??
I need to do more investigating ... I'll update when I get that LED Blinking :D
Also the pic reference I mentioned earlier in this post:

Setting a Static IP
I wanted to set the IP to be static.
I found this info on how to achieve that simply and it works great:
(*** Please Read Below for Correction***)
Edit the "/etc/wpa_supplicant/wpa_cli-actions.sh" file:
Add the "#" to comment out the DHCP Config, and then add the line below with the Static Config that you'd like for your Edison setup.
Editing this file is why I installed nano on the Edison instead of using Vi.
PS.... I did discover that I can not ping outside of my local network currently.
Will investigate this but believe the issue is related to some firewall config on the Edison.
till then....
AHA! Nothing to do with any firewall.
As it turns out I needed to add one additional line to the config file above in order to set a default gateway.
Here is the complete section from that file now ("/etc/wpa_supplicant/wpa_cli-actions.sh"):

route add default gw 192.168.1.1 $IFNAME

VI... It's just not for me
I'm using putty to SSH into the Edison.
In order to set a static IP address I need to edit some config files.
I don't like VI... so I came across a very simple way to install nano on the Edison:
wget http://www.nano-editor.org/dist/v2.2/nano-2.2.6.tar.gz && tar xvf nano-2.2.6.tar.gz && cd nano-2.2.6 && ./configure && make && make install
The above code worked for me immediately.
Enjoy!

IDE....IDK
My quest for Hello World!!
Well the first thing that came to mind when I received the Edison was its tiny size.. I mean really its tiny considering its basically a full fledged PC.
But I wanted to get going immediately. I understand that Intel is trying to grasp at the established maker community by incorporating Arduino boards and programming etc, but in my mind that would negate the value of what the Edison is.
Well... it seems you can write code for the Edison in multiple IDEs... Intel has Several to choose from..
So Far I've Downloaded:
Intel XDK and Eclipse
I have no idea which is better for what I want right now, or which is better for long term development.\
Looks like I'll have to just play with both and figure it out.
Who thought making an LED Blink could be so time consuming.....
