Arduino resets unexpectedly - NOT running out of SRAM

kenny_devon:
I have read extensively on the forum and elsewhere to try and get to the bottom of this without success, and there is a history of threads that tail off without any obvious satisfactory conclusion.

Sometimes we make a suggestion, which is probably right, and the original poster neither confirms nor denies that it worked. In other words, no response.

Sometimes the OP spits the dummy after an incredibly short time (eg. 2 hours) and says "well if no-one is going to help I'm going to MicroChip" or something bizarre like that.
