Lib 2.26 App 2.60, 1 Gb, marked as "Nokia MicroSD", that's it.
It's possible you need to upgrade to Benf 3.64.

Re: DSO firmware version 3.64

I think the need here is be able to turn on each injector exactly for the same time. Then you would compare each psi gauge reading to find an injector that spraying too much/little. Thats how I understand.

Re: hacking the nano into useful automotive tools

They took DSO Nano v2, added a $50 Capacitive probe, wrote the custom firmware, called it "uSCOPE" and available for $299. http://www.aeswave.com/products/Product.asp?i=1099 I want to know if anyone ran across this firmware? http://www.aeswave.com/new/www/images/products/1099/appnote/screen%20caps.j...

Re: DSO nano new bootloader firmware

There are few posts by andrey that talks about bootloader flashing, but for Nano V2. He actually flashed a blank chip. There is a v2 bootloader .bin attached in last post, pg 2. He is even open to questions.

Re: [Fixed] DSO Nano 201 V2.5 Battery drains while Off

I have contacted Seeed about the problem and they sent me a pair of LTH7 with a pair of 332 resistors. I could not wait for the mail man so acquired the LTH7 directly from Linear Tech. Soldered in the IC and all is well. When battery almost dead, it recharges at 460mAh-470mAh. Battery stays charged ...

Re: Installing BenF 3.64 from a linux box, no go

Are you pressing "Upgrade?"

I followed a guide on youtube and it said to press "Upload" which not only did not work, but messed up the unzipped files.

So I had unzip again and do Upgrade.

Just fyi.

Re: Defective generator, problem Nano V2

Alys, thank you for taking your time with great explanation. imho, if his oscilloscope part is still working, better to do next - switch off generator(if it can be programmatically switched off), look via oscilloscope probe or voltmeter, if Ax is high, but Yx is low. Looks like it works ok. As far a...

Re: Defective generator, problem Nano V2

I don"t know much about electronics but is 74HC125 chip a 4 in 1 fast switches? I don't know its purpose or why it was used in design. Anyways, looking at schematic and datasheet I see An are Inputs, Yn are Outputs and Cn are On/Off pins. When Cn is grounded, then connection is made from An to Yn. I...

Re: Defective generator, problem Nano V2

Ok I took the measurements of tensions: L6=-3.7v L5=+7.5v EN85 pin 1=+3.7v Looks good. For Pin 9(U9), I did not have any signal with the screen and after 15 seconds, the U9 becomes very hot. Wow, my U9 is cold, never seen it even get warm. I am guessing its shorted inside or Gen Output is shorted. ...
