Fetch Alpha2 released in first post.  Let me know if Due works.


 The frame rate seems to be working as it changes when variables are added or removed from the list. However, I get no data change "it shows 0" and it also does not graph or change data with Uno using 1.0.2 IDE

 It is definitely finding the sketch I uploaded and the variables but data is not the changing.

cyclegadget, you may have to copy the new Alpha2 DataLogger library files into the arduino libraries folder, replacing the files from Alpha1.

  Update! Problem solved! Fetch Alpha2 Release works with both Due and Uno!

  I must of had some old files from Fetch Alpha1. I removed all Fetch files from my Arduino IDE to make a clean start and replaced them with the new Alpha2 files.

 I tested Fetch with both the Uno and Due back to back and it works great!

Job well done drl81!

cyclegadget, thanks for the confirmation.  i can't take all the credit, i've been working on it with a friend who has helped a ton and may show up on this forum at some point to help answer questions, etc.

anyone who is giving Fetch a try, let us know if there are any specific features or fixes to prioritize for next release.

 Another update! I tested the my sketch with the Teensy 3.0 and it was success!

 Teensy 3.0 works with Fetch!


 One note: I had to use a delay(20) because my Fetch datalogger would freeze, possibly because a buffer problem (with the flood of data) with my computer. I believe the user needs to limit how quickly or how often the sketch reports data to the computer.

Don t know if this helps, the values in "Frame Rate" are changing.

I went to settings and selected the right COM, and the baud rate, everything else unchanged.

Thanks.

serbar, sorry to hear it isn't working with Leonardo.  I don't have a Leonardo, so it's hard to say what is going on.  After reading the Leonardo Getting Started Guide, it seems the Leonardo is a slightly different animal when it comes to the serial port. 

It sounds like it re-creates a virtual serial port on the PC each time it resets.  Are you sure you're selecting the correct serial port #?  What baud rate are you setting in Fetch?  (Baud rate setting in Fetch should match the SERIAL_BAUD definition in DataLogger.h, default is 115200).

The progress bar doesn't mean anything yet. We should probably remove that until it means something, to avoid confusion.

Yes i sellect in Settings of Fetch 115200 baud.

There is a thread running on this kind of issue for Leonardo concerning similar programs like Fetch.

serbar, thanks for the feedback on this.  i've been on vacation and haven't been able to dig into this too deeply.  i skimmed the discussion in the link you posted. 

in Fetch, have you tried going to Communication->Settings and trying each of the options for Handshake? 

if none of those options work, we should be able to release something soon that enables DTR.  we'll want to verify it doesn't screw anything up for other arduinos as well.

I look forward to news from you guys.
