i'm sorry if this turn out to be a silly question..
i just bought serial LCD character 20x4 for my project which have 2 type of input can be feed in, one is via RS232 serial and another one is TTL.. i just dont understand which one is the best for me to send a text via serial using serout, exp. serout 0,T4800,("bla bla bla...")
and.. what is TTL interface actually??? when can we use it? the diagram of TTL solution looks like very simple to interface with, i'm interested to try but don't know how to, especially to send a text to the LCD.
btw, the LCD can only be set to 9600 (by default) and 19200 baudrate.. if i'm using 18x, and i overclock the chip to 8MHz instead, am i using the right command for previewing the text? exp. serout 0,T4800,("bla bla bla")... seems like it doesnt wanna show me the right character come out..
