But i couldn't get the value of temperature. But if i modify the same program i m getting an exact output for 8-bit LCD display. So, are you saying that the display of the project name works in both 4-bit and 8-bit modes? If so, then this obviously narrows the problem down to something in your temperature display part that doesn't work in 4-bit mode. Quite possibly, your temperature display code relies upon something that is (or just happens to be) true in 8-bit mode, but not in 4-bit mode. You need to review your code carefully, and think about what this might be... By The Way: You would address Neil Kurzman as "Mr Kurzman"; I would be "Mr Neil" ;-) |
