I think anyone knows that search in google is useful way to find info,but We must spend much time to see and evaluate all 100+ links and extract the info that we need,forums like as this is useful because the is a shortcut to info that members need,we spend little time to find our needs and people share thair useful codes with others and share their experience with other ,this is useful for all and we can gain time and reduce cost in many respects.

I hope instead of responses like as "you can find in google if you are not lazy" we have better helps and shortcuts to codes directly.

I agree that a search on Google can be cumbersome to sift through, but what about a search right here on 8052.com.

Bit banged IIC has been discussed umpteen times and one of the first things that would pop up would be a suggestion of going to the horses mouth (Philips).

What we see here is rather typical "I search and find it in assembler and also find that some say it should not be done in 'C' but waaah, momma I want to do it in 'C'" and until someone gives in I will not accept suggestions of a search that just show assembler.

I do not know which schools, books or whatever that suggest you can do precise timing in 'C' but they are probably the same that argue that the earth is flat.
