I meant that he's not posting as "just" a user, but as a mod.

I think it is easier to get the moderaor status than it is to get rid of it.
I may be wrong though  smiley-roll

Dat is nou net wat ik aan zat te denken toen ik dat schreef.
Ik noem dat wel anders. Namelijk  een ID 100 T probleem.

Buiten dat, denk ik niet dat dit is waar Jantje naar op zoek was.
inderdaad.
Ik heb ondertussen dankzij de hulp van nico een hele hoop connectoren gevonden.
Uiteindelijke bij tayda een hele hoop connectoren gekocht. https://www.taydaelectronics.com/catalogsearch/result/?q=Housing+Connector

6  Products / Arduino Yún / Re: IDE 1.5.7 missing SPI library on: July 20, 2014, 07:14:15 am
Each core has its own version, its not in the root libraries folder.

arduino-1.5.7\hardware\arduino\avr\libraries\SPI
arduino-1.5.7\hardware\arduino\sam\libraries\SPI
I really do not understand why this is so given the new library specification.

I strongly advise using AES for wifi in all cases. Add mac adress filtering when you are at it.
I have set my wifi at home with AES and it works fine with yun. So it should work at your uni as well.

9  Products / Arduino Yún / Re: yun mega: reset the mega in reset-mcu (code needed) on: July 18, 2014, 10:54:49 am
placed some other batteries so I could do some testing.
Code:
cat /dev/ttyACM0
works but I have to press ctrl+C because the stream isn't closing.
But this set me to think and I came up with this solution:
 
Code:
head -c 0 /dev/ttyACM0
This works like an charm and probably works on any linux.

Why it works?
Head opens a file and prints the first lines. so
 
Code:
head  /dev/ttyACM0
may work if the arduino is printing to Serial. However mine is not and the delay may become to big.

 
Code:
head -c 0 /dev/ttyACM0
The -c 0 (zero no capital O) says to print 0 characters. So this will open the file and close it.

Thanks for the lead :-)

@sonnyyu
Ach now I get it. I'd prefer a Linux command though. As The hardware is finished and the mods I did make it more difficult to upload to the leonardo.

@arbor
I have some battery issues (another 500 euro down the drain  smiley-cry ) so I'll test as soon as I have the  hardware running again.

Thanks for the response. However I'm looking for code to run on openwrt that will reset a mega that is connected to ttyACM0.

13  Products / Arduino Yún / [solved] yun mega: reset the mega in reset-mcu (code needed) on: July 17, 2014, 09:40:31 am
Hi
I hacked my yun to replace the leonardo by a Arduino mega. I use upload via ttyACM0 and that works all great.
However when I run the reboot command in openwrt it doesn't work because the mod to reset the leonardo does not work to reset the mega (I tried to connect the reset line to the mega but that didn't work)
So basically the leonardo is reset (who is not using ttyATH0) but not the mega (that is using ttyATH0) so the boot process of openwrt does get interrupted.
I was wondering whether there is a easy command to reset the mega using ttyACM0 that I can put in reset-mcu.
A search didn't reveal anything trivial.

Best regards

The due has HID as well and the yun (which is a leonardo+ a linux running openwrt).
have you looked at the teensy? There are couple of them and they all have HID?
https://www.pjrc.com/teensy/
The teensy3.1 (say due ++ in a small package) is currently on sale for 17$ http://store.oshpark.com/products/teensy-3-1
