- Wed May 20, 2015 8:23 pm #18013 I'm working software that will send an email (via Pushingbox) when a smoke alarm goes off. The software is operational, but I would like to show debug info on a web page instead of printing everything to the comm port. The end application will not have a computer attached, and when something doesn't work I would like to look back at the debug info on the web page.

My main problem is there a way to reserve a block of memory (around 1K) to have the latest debugging info and get rid of older debugging info?

the variants i learned so far are:
[list=]use some persistent memory of the rtc[/list]
[list=]write to flash[/list]
[list=]add an external eeprom via i2c (?)[/list]
[list=]send the information to some server[/list]

For those variants the forum contains examples.

Hope that helps,
Cal
