I got this unit and the demo works fine. Here are some questions.How do I record a CSV instead of a TXT. CSV can be opened easily by excel and is formattedWhen is the system reco...

Hi, When using a terminal program I receive correct human readable text. But when viewing the txt output in the logger from te same device it shows lot of strange characters. I use the same baud rate in both cases. Each readout session does show the same sequence of characters. Should the logger work for any rs232 serial output other than arduino? Can anyone help? The sending device has a 12V power supply.

What if the data is logging and the memory is full will it delete the oldest one and create new?
Also how do we delete the file after we reach day 30 of the month to create new day 1 file...
These facilities are required for data logging

This module will automatically save the data, "S Button" will only save the current file and create a new file for storage.

You cannot change file name from txt file. In Excell or other spreadsheets just import the txt file to excel. You cannot specify anything but a numbered file. In config.txt on the serial data logger you can modify starting file number...i.e. 001.txt and can change Baud rate , but insure that you match the Baud rate on Serial() in your code and also that config.txt baud rate match. If not you know what will be the end result, garbage in file. Be sure to format your Serial.print statements for some form of delimiter between values..i.e '\t' tab, " " space, "," comma delimited for import into excel.

The time save for your file after 24 hours you will have to calculate from millis(). When you upload your code to the Arduino it starts the millis() timer so you would have to calculate the digitalWrite(SPIN, LOW) to save current file. The datalogger automatically starts the next file in sequence. If current file is 001.txt then next file will be 002.txt, if your clever you can edit the config.txt file to start the file number to current day of month or even the Julian Day of the year would probably make more sense.. 16th day would be file 0016 begin file for data logger. Since the Arduino uses millis() to determine up time then you would have to upload the code at a fixed time daily or go into the math involved to calculate 24 hours of elapsed time. ((60000 milliseconds per minute * 60 Minutes per hour) * 24 hours.) so elapsed millisecond timer would be 86400000 millis() elapsed since power up. At that value you would do a digitalWrite(SPIN LOW) to save the file. Then delay(2000) then do a digitalWrite(SPIN HIGH) to start next sequental file. Hope that helps and God bless.

Hi there, everybody happy with the serial logger? Anybody else has got problems using the logger? Mine „freezes“ after a minute or so, stopping the led blinking, and having disconnected it from TX and Arduino Power, reading it on my notebook shows up FAT problems while reading the last file written! Thanks for further comments!
