Excellent! :)

I think the above post is worthy of a PDF available for download from the repository (perhaps even an editable word source so others can add to it).

I still have a couple open questions :

- Is the SINGLE trigger mode working (continues sampling with no screen update until trigger)? How do I restart scanning for the next trigger event?
- How can I stop/start sampling (freeze the display in any trigger mode) and then pan screen left/right to see more of the captured waveform?

Don't know about anybody else but I'm having trouble changing the vertical scale using the "up" button in "Se" mode. I can move the waveform up and down by holding it as described, but just pressing up doesn't reduce the volts/division.

Edit: I've got hardware v1.1.

Edit 2: The "up" button needs pressed several times in any mode to register it. Is it polled or does it use an interrupt?

Maybe something jamming the up button?

Thank you, Paul! Very good. The DSO becomes better.

Paul, your firmware is the best, but you can include LOGOS to reeplace seedstudio, dso nano... originally my DSO shows e-design. when I try some firmwares I lost it.

Hi guys!
I want to share my experience with the DSO nano here.

Just a two days ago I have received one from ebay. It was flashed with the latest Paul 1.5.20 firmware. So everything was ok but the voltage readings was biased with +800mV.
Seeed firmware has no gain and zero adjustments. Paul`s one wont write to microSD its settings.
The 2nd way was more clear so I have started my little research.

Here`s the results.

To have an opportunity of using the microSD card with Paul 1.5 do the following step-by-step:

1- Get an microSD 2GB card (do NOT buy Kingston!). I have Apacer 2GB working good. Maybe you should switch between several vendors.
2- Put the card into the card-reader or notebook and format it in FAT (FAT16) with standard cluster size.
3- Put it in the DSO Nano
4- power the DSO up while holding the M button. Do NOT use any DSO functions to not ruin the microSD filesystem!
5- connect the DSO with the PC with USB cable
6- windows users should check up "my computer" for new removable drive appeared.
6.1-If the new drive have appeared but you see window 'hang up' and too sloooow - this microSD card is inappropriate for your DSO. Return it to shop, get another one and repeat from step 1.
6.2-If windows says 'disk is unformatted - format now?' - its OK! Click YES, then select type FAT and do full (not quick) format of the flash card.
6.3- maybe you even see an empty disk - so you even dont have to format it.
7 - So you have seen a new drive and can access it from your PC. Pick up the archive DSO.zip attached below and extract files from it to the root folder of your microSD. Take a close attention: their names must contain small letters ONLY (i.e. config.dat not CONFIG.DAT). If not - simply rename it.
8. After all just cycle the power.If you see the mV values instead of Freq and Hz in the quick measure tab and the horizontal cursors are 0V and 5V - you are having success!

Special for those who have no usable SD,but ref wave is limmited to 4,
also worked for those who have an usable SD.
