Because the use of cheap i2c converters (china ware -SaintSmart pcf8574) for 1602 or 2004 LCD displays do not work together with the current i2c driver for HD44780, I figured out, that the nibbles of the output port are just swapped. So I added a new subdriver for HD 44780 called "i2cS". Since I do not know about CVS I added it to the package manually - including documentation. Attached you will find a package, which works with the cheap chinaware i2c converters intended for Arduino. Perhaps somebody can put it into correct format to get "developer conformity"
