Step 3: Setup the Wixels - Install an app & Flash that LED!

Next follow http://www.pololu.com/docs/0J46/3.d to install the Example_Blink_LED app; rather than double clicking the WXL file, you should use the Wixel Configuration Utility (WCU) to get used to it. See the WCU at picture one .

I have only used this with Windows 7, note the mention of specific things you need to do with XP. Sorry I can't test with XP but if you have an issue post a comment, I or someone may be able to help.

When you have completed the 3.d steps in the above link, you have a Blinking LED, see picture two .

Pretty straight foward.

So we now have a working Wixel installation.

You should now swap to the second Wixel and set it up with the Blinking LED app. This is so we can use either of them in the following steps without having to initialise it.

While we are using the WCU, press the 'Get apps...' link and download the USB-to-Serial & Wireless Serial apps. We will be using them in following steps.

Also download the Wixel_Instructable.zip file below, right click & Save As to give it a meaningfull filename rather than 'able randomness. This has a few demo programs for the next steps.

Next - we get to plug stuff in and do something real!
<p>Thankyou very much for this good informations, but I need a little bit more information and help for my project, could you help me ? In my project I am using 2 PIC 16F877A and one of them reads a few sensors may be 8 pieces and if enabled (for example if pressed any button) this firs PIC sent this data from first PIC to second PIC as a byte like these &lt;10011011&gt; 5 of them high 3 of them low, other than if not pressed enable button it will do nothing. I have 2 pieces pololu wixel. Please help me !</p>
<p>I have not used PICs.</p><p>Are your PICs 3.3v?</p><p>If you have it working when the two PICs are hard wired together, then the easiest way would be to load app 'd. I/O Repeater' (see list on step 1) and config the pins so that: PIC1 output pin -&gt; Wixel A pin# -&gt; Wixel B same pin# -&gt; PIC2 input pin.</p><p>If not 3.3v you need to translate the voltage. How depends on if PIC v is &gt; or &lt; 3.3v</p>
<p>If that has timing issues, app 'b. Wireless Serial' should help.</p>
Test comment ignore
there is no serialportserial.exe file or script in the zip documents. Is there another link we are supposed to download it from?
Ooops...sorry. New zip file uploaded with serialportserialIO.exe (&amp; .ahk) added.
Wow, this is a great write up! I can't wait to see your next steps on bot design; do keep us updated with your progress through more awesome instructables!
Good stuff. Thanks for taking the time to write this guide.
Thanks.<br> <br> Update: Pololu have released a Arduino Shield for the Wixel http://www.pololu.com/catalog/product/2500,<br> doco is at http://www.pololu.com/docs/0J47/all<br> It has voltage converters to work with 5V too :)<br> It can also serve as a proto-board for independent Wixels.<br> <br> It looks good, I just got one and may do a small -ible (but don't hold your breath - lots going on this time of year...)
This was a very good tutorial. There are not many Wixel resources for some reason. Maybe it's because the Wixel is still pretty new. However I had an issue with the autoreset feature with the Arduino Pro Mini and just wanted to share that I used P0_0 to the Pro Mini's GRN pin and it allowed it to auto reset after a wireless sketch load. Just though I'd share that in case some one else had that issue on the Pro Mini not loading or getting the AVR dude error message.
Thanks. And thanks for sharing the tip.
Updated the C# code with a few minor bug fixes.
I'm learning Visual Studio &amp; Visual C#, sample code added to new last step
Pololu have released the I2C app mentioned in the last step. So you can now control hundreds of I2C interfaced peripherals with your PC, with either the locally connected Wixel, or the remote wireless Wixel.
