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.seeedstudio.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!
REMARKABLE 3rd part firmware
Benf can’t stand our retard response on suggestions, and decided to rewrite a new firmware, and wrote a much better one!
The DSO Nano project originated as an open source effort. Unfortunately these contributions appear to have been cramped by individuals with limited programming skills and even with the most recent official firmware 2.5e release we’re not much further than a pretty enclosure with potential. To release this potential a complete rewrite of the firmware was needed.
- 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)
Download here and take a try! Thanks again BenF, you know much better what people want from the firmware!
Japanese Manual for DSO Nano v2
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 🙂
