sta file!!! what does it all mean

[newbie323]

Can some tell me if the following information from the Program metrics file which my program has produced means, in terms of reliability, robustness.

I am developing a consumer product and i am now trying to clean the code up and hoping that the program will not die. It seems that I can not get : Est Delivered bugs down to 0. Is it reasonable to expect 0 % bugs if not what number is reasonable. This also relates to Cyclomatic Complexity of 184 and maintainability (MI) 130.

what is a acceptable values be for these.

In addition is a file which is 1680 lines to large??? (please note this is a LCD module driver and the LCD pixel layout is all over the place therefore required a lot of while loops and if elses )

And also Stack used: 10 worst case (out of 29 total available) please can someone explain this or lead me to documentation that might give me more information.


ROM used: 20580 (63%)
20580 (63%) including unused fragments

2 Average locations per line
9 Average locations per statement

RAM used: 540 (35%) at main() level
