1) I set up a board with a pic18f254, using a pot for sensor input and a serial port for communication. Pic code is from Tom Igoe's Network Data Logg suite.
3) Upload the PHP code and text file. Since PHP has to write on the "datalog.txt" file, make sure to set correct permissions on the text file.
4) Here is the final Data to the text file on the web.
Questions & Problems
In the final Data, I was getting the same minute. Is this error from the code, conection, net server?
Also the value of the sensor is not reliable. I have huge range but static. I cannot see much chage athough I turn to the most high and low I don't see the change. Three possible problems I guess. Net traffic delay, calculation from the code or the board set up.
