Is there no solution to this problem or is it something happening on my installation only. I had no replies on my earlier post and I  need to solve this problem. I am running Windows7 64 bit and my processing version is 1.5 I installed a jre and jdk.

Will anybody let me know how to fix and at least let me know if this is an exception or if it is quite common.

I managed to get the code not to crash with any key press except for cancel escape and the small cross on the input dialog.

Will anybody please help on that? Is there a unicode character corresponding to these keys so I can filter it or can I disable them or is there a way to display a userinput dialog without a cancel button?

Thanks

Hi all
Can anybody please help with this code?
Why can't the code in line 96 "println(y1);" not see the code in line 95 and how can I solve that?
Thanks
Bertus

Hi all

I bought a 2560 mega board for a big project. I installed StandardFirmata on the board because I want to do all controlling from my laptop. The problem I have is that analog pins 6 to15 don't return any values. I have ten analog sensors on pin 0 to 9 and pins 0 to 5 return a value for me but pins 6 to 15 don't. All my digital pins work as well as I have tested them as outputs and they turn a led on and off. the problem is just on the analog pins. I don't understand this because if the software thought that it was a board with less analog pins then there would have been less digital pins as well and I would have had a problem with them as well. I spend two days now looking for the reason but I am beaten. Can anybody help please?

Thanks
