Could you post your entire code here? At least I did not see where you write "TEMP:" to screen. Also at which point you do your LCD clear routine. Problem might be in that code area...
At least you managed to get DS18B20 to work. That's positive!

You are not using "LCD_Clear:" routine anywhere, so you are not clearing the LCD at any phase.

Add this before "Main:"

call LCD_Clear

If that doesn't help, try to replace manual LCD write commands with SHIFTOUT. Similar what you have in "LCD_ByteOut:"

I meant this (below) instead of "CALL"

GOSUB LCD_Clear

Why you are using CALL, shouldn't those be GOSUB instead?

I have learning again one more thing. Thanks to You, all members of this great forum. I'm happy !
Now, I want to make the next step : "up-grading" the schematic from here - http://www.picbasic.co.uk/forum/show...7&postcount=35 for using with N3310 display. I will keep You on line ! All the best !

Now my project it is in this stage - see photo 1. I ask -again, sorry ! - for help : how to make like in photo 2 ? I do not understand how 'advanced' to next line (I think because of my poor english... ). I read the N3310 display .pdf and many examples, but still don't understand... Can somebody explain to me, please ?
