PCF8574 Controller

Actually i made the same program in Delphi7.
Some one asked my if i could change the application.
But after a reinstall of windows on my computer i couldn't find a free download anymore.
This is how i came up with Lazarus aka freepascal.

I improved it a little bit. It's now possible to set the comport. And also the address of the I2C
device. An ini file is used for this purpose.
