mrmx / dsonano Goto Github PK

What steps will reproduce the problem?
1. i tried to c the ripple voltage, but could c it...
2. i looked at this website: http://code.google.com/p/dsonano/
3. i couldnt find a howto that explains how i can get the data to my linux box

What is the expected output? What do you see instead?
on a self made switched-mode power supply i would like to c the ripple 
voltage...
therefore i connected the black clip to ground (0V) and the white to the output 
voltage (5.8V)... then i saw a flat line (+/- 1 pixel)... i couldnt zoom in (i 
mean: ypos stopped at line 0 and there is no way to use a factor), although the 
voltage has a 12bit resolution, doesnt it?

What version of the product are you using? On what operating system?
i bought it at 2011-04-21...

Please provide any additional information below.
1.
dsonano is cute... and it is my first oscilloscope with more than 
10kSamples/sec... :-)
2.
can i download the data to my linux box, where i could analyse it then?
3.
or should i use a stabilized 5.5V reference voltage instead of 0V?

Best way to describe this defect is via an example:

Let's say I have a signal that is 50mV peak-to-peak has a 2.5V offset. 

To see the signal up close I want to set the scope to 10mV/Div and offset that 
2.5v. The current sw version does not allow me do to that simple task!

Hi

thanks for your work.   I am having problems for compiling the latest 2.5e 
version of the firmware.

when I try to open it with IAR 4.2 it give me an error saying that the file was 
saved with a newer version of IAR.

also, i have tried with IAR 4.5 it compile the source very well, i convert it 
to dfu but when i try to upgrade it just fail...  like if the dfu size were 
0kb... 

What steps will reproduce the problem?
1. I installed DfuSe V3.0 demo (um0412.zip) from wiki.
2. I run DfuSe demonstration.
3. Windows XP pops up saying "DfuSE Demo has encountered a problem and needs to 
close."

What is the expected output? What do you see instead?
The program to run...

What version of the product are you using? On what operating system?


Please provide any additional information below.
I'm running Windows XP x86 home edition

What steps will reproduce the problem?
1. connect the function generator to the input
2.
3.

What is the expected output? What do you see instead?
it would be good to see the generated function on display for better analysis.

What version of the product are you using? On what operating system?
dso nano 2 

Please provide any additional information below.

I just received DSO nano v3 and installed the firmware from the link at 
http://www.seeedstudio.com/depot/dso-nano-v3-p-1358.html (DSO Nano V# Firmware 
4-11.hex).  Upon restart the screen is black and white and inverted.  The 
product worked fine before the firmware upgrade (maybe upgrade was not 
necessary but didn't think it could hurt).  Any suggestions??

I have attached a photo of the screen on startup

What steps will reproduce the problem?
1. Try to find documentation
2. Fail to find a document
3. End up here begging for help
What is the expected output? What do you see instead?
ant locate a reference table or document explaining whst versions
of firmware can be loaded on the different models.

What version of the product are you using? On what operating system?
I got the DSO201 with a 1.5.20P version
What is the firmware that can be loaded to get rid of the 
bugs that are in the stock firmware ?

Please provide any additional information below.
Im despaired .

Any help figuring what to use will be appreciated

What steps will reproduce the problem?
1. When trying to upgrade APP and LIB 
2.
3.

What is the expected output? What do you see instead?
Power up holding down button screen says "copy hex or bin file to DFU virtual 
disk (just like the quad), I copy the new files APP and LIB and the nano shows 
files as RDY,  all ok so far, turn nano off and on and it still has previous 
APP running. This  nano was supplied with LIB 2.26, APP 2.60, after contacting 
my supplier LIB 2.25 and APP 2.60 were e-mailed to me from  guojun Ding, the 
nano accepted this LIB file and APP file so I now have LIB 2.25 APP 2.60, so 
this method appears to work for these files but I cannot change to benf APP 
3.64 with LIB 3.53


What version of the product are you using? On what operating system?
 Nano with the square button for up,down,left,right selection, e-design device firmware upgrade V3.20A,  LIB ver 2.25, APP ver 2.60


Please provide any additional information below.
When turned on with down button DFU demo can't find nano but it appears in 
windows explorer as DFU V3_11_A and the new hex files can be copied to this and 
it behaves as the quad scope, marks the files as RDY but when turned off and on 
returns to the existing APP (2.60)

1. Same as Issues number 10 and 11

Please help to solve this problem. Thanks

If there is already a way to do this please document it. 

I would like to have the battery status displayed on the screen.  One possible 
place to add it is within the first menu (AUTO/NORM/etc) Have an option that 
says BATT and will display the current battery level.

There are a few ways to display this info.  One possible way is that when BATT 
is selected by hitting OK, it will display the percentage for a few seconds and 
then go back to the last selection.  This gives an easy way to check the status 
and keep working if it's ok.

If the battery is charging, how about changing the GREEN cursor to RED or 
something similar.  I would also like to see a way for the device to show when 
charging is complete.

What version of the product are you using? On what operating system?
DSO App 2.5

Please provide any additional information below.
I'm new to the project so I'm not sure of any limitations. I'm probably asking 
a lot but anything is appreciated. 

 1- The open source of firmware v2.4 is not available on 'downloads' section.

 2- What are the differences between version 1.5 of Paul and the official version 2.4?

Wouldn't it be possible, and relatively simple to implement a simple high-pass 
digital filter (say, an IIR or a FIR digital filter) to add an AC mode to the 
oscilloscope (to filter out the DC level)?
That possibility must have been considered before, but what stood in the way of 
implementing it? I can't seem to compile and upload the code (all the guides 
for that are offline on the wiki) but I can try to help with the filter design 
if needed.

The guide explains how to build the firmware but not how
to build the needed support library ?

We will prepare a detailed, step by step documentation explaining explaining 
following topics:
1. Setup tools and environment
2. Upgrade Firmware
3. Start building your own firmware
4. UI modification
5. Functionality Mod.
