Hi everybody! I have had a few request for information about the small portable pocket scope I'm using in a few of my videos, so I'm going to share it with you. In this video, I'll walk you through installing the BenF Firmware as well take you through the menu structure and functions of the device. Seeed Studio did a fantastic job with this little device, it really is an awesome portable tool. Compared to the stock firmware, the BenF firmware has better navigation, features, and the SD card features work a lot smoother.

The Nano (DSO Nano v2) is a great tool for a great price! You can get them for under $100, they come with a case, 2 sets of probes, a stand, and it's open source!

Below is the feature summary from the manual and the links to the scope product page, firmware manual, firmware and firmware install tool.

*UPDATE: Adafruit now sells this scope! 🙂

Thanks to Seeed Studio and its DSO forum, sufficient information has been provided to allow the stock firmware to be replaced with a custom version. Based in part on the official 2.5e source release, V3 has been developed as a complete new firmware replacement. Fixes and new features include the following:

•  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, compact and
more responsive code)

•  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 and restored from SD card or flash memory
(default power on settings).

•  Waveforms can be saved to and restored from SD cards

•  Screen capture can be saved to bitmap files on SD cards

•  Snapshots of the full DSO sampling buffer can be exported to XML formatted files for
further processing and analysis

•  XML formatted files can be imported to both the primary channel and the reference

•  Use oversampling and averaging to detect high frequency components on lower
frequency waveforms

•  Choice of average and peak acquisition modes

•  A number of issues with incorrect SD card support and file handling in 2.5e have been

•  Files and directories will be created by the DSO Nano as needed without having to
preload template files

•  Automatic waveform tuning (FIT mode) can be selected with a dedicated key

•  The full sampling buffer can be panned left right on the Nano display

•  Control sampling buffer usage for pre or post trigger priority or fast sampling rate

•  Waveform resizing and vertical scroll capability (zoom in on area of interest)

•  A more relevant collection of information fields is selected for on screen display

•  A more relevant selection of measurements

•  Simultaneous view of all measurements

•  Use common abbreviations and terminology

•  A completely redesigned user interface (no annoying blinking or color abuse)

•  Automatic ground level calibration and manual gain calibration for all input ranges

•  User selectable grid light intensity level

•  Fine tuning of output frequency to three digits

•  Set duty cycle (PWM) of output frequency from fully-off to fully-on in 1% increments

•  Single button quick select for frequently used functions

I'm trying to update a new - out of the box Nano V2 to Benf 3.62, drivers installed well with dfuse 3.0.1 on windows 7 64 bit. the upload of app 3.62 and lib 3.52 seem to go fine, but when I turn off and back on, I still see the Seeedstudio firmware prompt. Am I missing a step? The nano display always reads "firmware upgrading... Please Wait" - forever - should I keep waiting? or just off/on?

Any suggestions?? Confused
