fprintf to a text file

[tepes]

can anyone give me an example of how to to print the data from the PIC in to a text file? something like bellow...

Hi...

where would such file be?
SD card?
on a host PC?

Programing on a PIC is not like programing C++ on a PC where you just print to file.

the easiest way is get an "Open Log" set you back ~25 bucks... does all you want.

or buy an FTDI Vinculum based USB flash drive module for same money +-

SUPER easy to create files,save data,etc. and 100% PC compatible !

I needed the .txt file to be on a computer and to fprint in to it by using RS232! But instead I print the data to hyper terminal now, and then I copy the data to a .txt file and then I use a C++ program to create a new file where the data is formated the way I need! It takes a litle more time but I obtain what I need!

First, forget fprintf. This is designed for talking to a serial stream in the PIC, or a open file on the PC, and isn't the tool needed here.
On the PIC, with CCS, 'printf', is a generic output tool, able to route it's output to _any_ output routine using the syntax:

printf(routine_to_use,"what you want to send");

If you have a file open on an SD card, using the fat.h library, this offers 'fatputc', allowing you to write a character to this file. So you can use this as the output routine for printf, and write the text to the file. Obviously open first, flush & close when finished.
This then puts the data (text or binary), sequentially into the selected file.

.... you can set hyperterminal to receive/capture a text file.
so basically what ever you see printed in hyperterminal is saved to a TXT file...
its a standard feature of Hyperterminal.

You can set your PIC to output your data in the format you want.

I did this for a data logger i was building a while back.

Each line the pic printed was

Thank you all for your help!
