Andy: includes a simulator
Erik: How do they do that (any pinning, any brand) ? Or is it that if you copy the Keil design exactly, you can simulate it.? Not sure how Keil does it, but it's certainly possible to allow the user to configure an LCD in a simulator such that you define what line RS, RW, and E are connected to, along with DB0-DB7. Or, if memory mapped, define the XRAM addresses for writing/reading commands/text from the LCD. The simulator could even allow the user to define the required timing delays to make sure minimum timing was not violated. At that point, as long as the LCD conforms the 44780 standard, you'd be 99% sure that your code is working. You certainly don't need to explicitly simulate millions of different configurations. You just give the user the ability to configure well under a dozen parameters regarding how the LCD is connected and you'll have covered the vast majority of the typical configurations.
