I2C Testing software

I came across this article the other day, while looking for something else.

It appears that in 2008 Jim Rowe had a problem with some I2C devices. He contacted NXP (was Phillips) and they supplied some software for testing I2C.

The March 2008 Silicon Chip article is available online(but not free) http://www.siliconchip.com.au/cms/A_110147/article.html however the software and board layouts are available to download at http://us1.webpublications.com.au/static/downloads/articles/110144_I2C_interface_sw.zip There is a small piece of hardware required to interface to the printer port. I do have a scan of the schematic, but no website to drop it on.

I haven't tried it yet, but it may help someone.

Cheers Mark


Good excuse to not throw out that old PC. The author also made comment that it worked okay on his win98se machine but threw an error on his XP.

He didn't have time to followup.....

At the end of the day...its free, except for a 4011 and a couple of fets, diodes, and some resistors.
