How can I display the info from a DS18B20 onto an LCD...

Hi there,

I'm struggling to get an LCD to correctly display the information being recieved from a DS18B20 temperature sensor...

I do have the code working for a 16F636 outputting serially to hyperterminal... but due to code space issues I have had to port it over to a 16F877... but whilst I get the uart up and running correctly I'd like to display the information on a LCD...

The LCD is already displaying correctly, so I have that side of things working...

But what I need to sort out is a way of using the printf command but instead of it sending the data to hyperterminal it displays it on the LCD...

this is the line I need to get working correctly on the LCD...

Code:
--------------------------------------------------------------------------------

printf("\n\r ScratchPAD DATA = %X %X %X %X %X %X %X %X %X \n\r",get[8],get[7],get[6],get[5],get[4],get[3],get[2],get[1],get[0]);

--------------------------------------------------------------------------------


Any idea's on how I would go about doing it?

Click to expand...

your printf() is expecting a function, putc() (both in stdio.h). so rather than using the stock putc(), you can redefine putc() to use your lcd routine that writes a char.

something like

if you want to output both to the lcd and uart, you just need to add a serial putch() function in there.

after that, recompile and you are reading to go.
