#twatch network LCD backpack / Re: Matrix Orbital commands?
Hmm.  Either I'm doing something wrong, or there's a bug then.
If I do this php:
Code: [Select]
$fp=fsockopen('192.168.1.19', 1337);
if ($fp){
fwrite($fp, "xFEx4111"); //put cursor at postion 0,0
fwrite($fp, "xFEx58");  //clear display
sleep(1);
fclose($fp);
}

I get the blinking block cursor at the upper left corner, as I would expect.
However, the two lines of scrolling text continue to scroll, and after a few minutes the twitter feed updates and continues on its merry way.

Any ideas?

#twatch network LCD backpack / switching to Matrix Orbital mode
I'm having a heck of a time switching to Matrix Orbital mode, and having it stick.  I start with 0xFE 0x47.  Then is position 0 0x00 0x00 or 0x00 or 0x01 0x01 or something else?
Or is there another command which should do it?

Also, sending 0xFE 0x99 does not display the IP address information, or if it does, it does so very quickly and is overwritten.

Also, which version of the #twatch firmware shipped with the device?

#twatch network LCD backpack / PHP starter
Anyone wanting to send data to the #twatch using PHP, here's a starter for you:
Code: [Select]
<?php
$fp=fsockopen('192.168.1.8', 1337);
if ($fp){
fwrite($fp, "xFEx42");
sleep(1);
fclose($fp);
}

#twatch network LCD backpack / Re: Great, now what?
Ok, so that's good to know.  Tried it again, and gave it a little more time to get rolling - and now it's working!  Well, mostly.  LCD backlight isn't lighting, but the contrast adjustment is working.  So, it's mostly good.
Will do some reading, see if I'm missing something on the back light.  Any suggestions in the mean time?

#twatch network LCD backpack / Great, now what?
Got my #twatch, and was quite excited to hook it up.  Went and got a universal AC/DC adapter (Philips is a reputable brand, right?), set it for 6 volts, and plugged it in.  No joy.  So, I got out the multimeter to check things, and found that when set at 6 volts it was, in fact, spitting out 9, and when set to 7.5 it was outputing 11.  Tested another AC/DC adapter, just to be sure it wasn't my multimeter - it's reading correctly.

So, given that I probably applied too much voltage to the #twatch, is there any way to repair it?  I get no ethernet lights, no lcd display.  Is it cooked?
