I am some what new to 8051 programming and I need a little help or guidance with a program I am working on. The program basically takes incoming serial data and displays it on a 2x16 LCD display. The program does not seem to want to display the data, I have check and the serial functions seem to be working. I was wondering if any of you could take a look at my code and perhaps tell me where I am going wrong. Also what I would like to be able to do is when the serial data is complete on Line 1 of the LCD drop down to Line 2 to continue displaying the data. Thanks in advance!
