can u edit that changes for my code?I see in your code that in displayValue() function LCD data port is referred as DATA and you are assigning value of value to DATA, So, you should use #define DATA P2
Zip and post your Proteus file. I will see if it works.
thank you very much jay.You code is working fine. See attached file and image.
yes jay .i was set baudrate in hyperterminal 9600/databit 8bit/parity none/flow control none .Are you simulating in real hardware? In the code you have set baudrate 9600 bps and you have to use the same baudrate in hyperterminal. Is you MAX232 Ok? Are you getting garbage data on LCD? Try with the v2 file I have posted in my last post. Can you post your MAX232 circuit?

Your MAX232 connection is wrong and maybe it is already damaged. See image.
my rs232 circuit is right that is working with rs232 Bluetooth module.i.e i can send and receive text from that circuit.Your MAX232 connection is wrong and maybe it is already damaged. See image.
Try to send inverted data from hyperterminal.
yes i just opne the hyperterminal and then select the port and set all baudrates,parity,bit,flow .Post the screenshot of hyperterminal. I don't have hyperterminal. There should be a invert check box. Are you sending ASCII data to MCU?
There isn't an invert option with Hyperterminal or other standard terminal programs, e.g. Putty. What should be it's meaning?There should be a invert check box.
