Have you read Application Note 161 Interface and Simulation of an LCD Text Display http://www.keil.com/appnotes/docs/apnt_161.asp You can use this to run your code in the simulator, to check if your code is correct. If the Simulator shows that your code is correct, but it still doesn't work in your target, that suggests that you have a hardware fault - although it could just be that the simulator does not quite simulate your particular device correctly... ;-)
