1  Community / Website and Forum / Email change failed: Unable to propagate the email change. on: April 09, 2014, 06:31:35 am

I'm trying to change my email address but it doesn't work. When I click on the link in verification email then I get this error message:
"Email change failed: Unable to propagate the email change. Please contact assistance."

And it's not changed. Any ideas please? And BTW what is "assistance"? smiley
2  Community / Website and Forum / email parsing errors on: August 02, 2012, 02:41:01 pm

I don't know if this issue it was already reported but has some problems with email parsing in case when it contains a plus sign. So for example if you register with your gmail alias like then in some parts of the system the plus sign is replaced with a whitespace. As a result you will not be able to receive email notifications about subscribed threads.
3  Using Arduino / Programming Questions / Re: algorithm to detect a blinking LED on: August 02, 2012, 11:32:31 am
By undefined I mean two things. Firstly I don't know the initial state so it may start blinking from being OFF or from being ON. Secondly I don't know the interval but it must be regular. If the changes are regular and there is enough of these changes then it's blinking, otherwise it's not blinking. Also it's important that I can get time from RTC and I can not use delay().

OK thanks guys so I know I will need three predefined constants:
- how many state changes until it's considered as blinking, for example 4
- minimum pause between changes, for example 30 milliseconds
- maximum pause between changes, for example 5 seconds

I think I have some ideas now...
4  Using Arduino / Programming Questions / algorithm to detect a blinking LED on: August 02, 2012, 06:10:12 am

I have Arduino with photoresistor attached to external device's LED. If this external device wants to signalise some error then it's blinking that LED. In normal operation that LED stays mostly OFF, but sometimes it can go ON without blinking. Blinking frequency may vary, i.e. sometimes it's blinking fast sometimes it's blinking slowly.

Now all I want to detect is just the fact that it's blinking. Let's say after three regular (but undefined) changes of state I would classify it as positive. What algorithm can I use for that purpose?
5  General Category / General Discussion / Arduino + NetBeans + FreeBSD on: May 13, 2012, 05:18:18 pm

There are some nice tutorials about using Arduino with NetBeans on Linux systems but they doesn't really work for FreeBSD.
I don't even need to upload the sketches from within NetBeans and I can do with running avrdude manually, all I want is a decent IDE and I'm already familiar with NB (please note that Eclipse is no option).
Did anybody manage to run this combination?

2) change the data type from "prog_char" to "char PROGMEM" in print(const _FlashStringHelper*).
I can confirm that your patch has fixed the problem here on Arduino 1.0 and avr-libc-1.8.0
Thank you!
