I created this library to help all the users of the LiquidCrystal library so they don't need to use a different library with different commands also when initializing the library do not put the r/w pin in the pin initializing command
the code can be downloaded from here.
look at the fourm post or see the liquidcrystal page
all electronics 24x2 lcd (and all other lcds on the liquidcrystal page)
