A few wrap-up on the DSO Nano v2 open source fruits!
Free open tool chain
Now Jerry have finished migrating from IAR to GNU tool chain, there is no longer 32Kb code limitation or commercial license concerns! Please join the discussion and try the new compiler from our forum: http://www.seeedhttp://studio.com/forum/viewtopic.php?f=12&t=1262
. Thanks to the help from everybody, especially tormod for providing the new dfuse tool working natively under linux!
- Proper three phase sampling (pre-fetch, trigger-fetch, post-fetch) guaranteed never to miss infrequent events
More efficient screen update (10-100 times faster than version 2.5e)
Eliminate all flickering and stuck pixels
Code is re-written to allow full compile time optimization (much faster and compact code all over)
A bug in Vrms calculation is fixed (Vrms is incorrect in 2.5e)
A number of overflow bugs have been fixed (calculations for large time/div settings)
Scan has been replaced with a proper continues real-time scan mode
Configuration profiles can be saved to /restored from SD card or flash (default power on settings).
Wave data (reference signals) can be saved/restored from SD cards
Screen capture can be saved to SD bitmap files
A number of issues with incorrect SD card support and file handling in 2.5e have been fixed
FIT mode is implemented as a function
The full captured signal buffer (3000+ points) can be panned left right for further analysis
A more relevant collection of data is selected for display on screen
A more relevant selection of measurements
Simultaneous view of all measurements
Use proper ISO abbreviations (e.g. milliseconds is “ms” not “mS”)
A completely redesigned user interface (no annoying blinking or color abuse)
Support two step calibration (offset and range)

and take a try! Thanks again BenF, you know much better what people want from the firmware!Finally, some new updates of DSO QUAD!
We have finished mold design and moving to trial batch now! They might be ready late this month or early Dec. A few beta units will be open for pre-order. Check out the infant photos of the prototype. The final product will be using different material, expect something neat .
