A blank eeprom is all 0xFF I think. Power failure exactly in that sub- millisecond which arduino needs to update a value is very unlikely.

Ok. Simple xor-ing 255x32bits int (or even adding) chunks and writing the result on the 256-th should be more than enough. On reboot xor-again, if the sum does not match...

[failtest.zip](https://github.com/ermtl/Open-Source-Ventilator/files/4381841/failtest.zip) Here-s a zip file with - ee_failsafe.ino which can be added as a tab to your project. - failsafe.ino - just to show how the two functions eeprom_write_crc() and...

feel free to ask me if anything isn't clear.

If we-re to share thoughts about critical systems guidelines, then people lifes should not depend on software/mechanics developed in

If you really want it to be safe, take it functionally. I mean have a function that checks correct pressure swings are registered and reset the wdt in the same...

I worry more by not having a [watchdog timer](https://en.wikipedia.org/wiki/Watchdog_timer). What do you mean by code corruption? AVRDUDE (or other flasher) does verify the code after it was written. Do you...

I would even go as far as leaving only serial interaction. Have a clear, well defined .. "protocol" between a control unit and an interface unit. The benefits are several...

Ok, that makes sense. I changed the second array index to depend on input from first and it can't optimize anymore. Thanks. On 11/8/18, Siarhei Siamashka wrote: > The memory...

What does it predict?
