Dear Friends,
Hello, I'm now designing a relatively complex and serious embedded system which also has 8051.
In the codes (mix C and assembly), I accommodated many error handlings. For example if system couldn’t position itself at the right place at a reasonably long time it comes back and retries. For each error situation I assigned a code which after error situation detected it's corresponding counter will be incremented in a flash(as 2 byte integers). Along with the number of the errors system saves the last date of every error code. I wonder how much error logging for purpose of maintenance is used routinely for complex systems by experienced users? is it just wasting of money or is it worth for complex systems? The system that I’m designing now would be the first model (there are no older models).

thank you very much
