program ADC and LCD

[danjoro]

hi, i have some problem about ADC and LCD.. I am trying to display voltage on ADC on LCD display in degree . and how about if i have 10bit and the lcd port only 8bit. I have not found any examples on how to do this. I'm hoping someone can point me somewhere so I can try to understand this. but the way, i use pic18f4580 and c-language..
Thanks for any help,

hi,
Look at Nigel's tutorials, the link is near my signature on the post.

I know that the tutorials are written in assembler, but they should give you an idea how to write the routines in C.

Also look at this pdf for LCD basics.

8 bit means that you send 8 bits over the dataports to the LCD to display the character, if you have 4 bits you"ll need to send 2 times the data to visualize the character.

What LCD-display are you using , you can use the library's from C18 or MikroC.
