Thank you Gabriel, just got the notice that you shipped my order!

Sincerely,

Carlos

hi,

it is amazing product!

i am interested with the graph plotting function for  2D and 3D. i will very much appreciated if u can share some of the knowledge,

thanks& regards,

I used AVR Studio and AVR Dragon to load V1.05 firmware.  I noticed several improvements.

My fingers are quickly learning the menu system, seems very intuitive.  It is a neat instrument!

On hardware version 1.4, the USB communication is done using a UART to USB cable.

The Xprotolab internally is just using the UART.

I think it would be very diffilcult to convert hardware 1.3 to 1.4.

So how are you doing USB communication?  Last we talked, you didn't think you would have room for a software implementation, and were looking at a hardware mod.  From what I can tell of the 1.4 schematic, it looks like you are taking the software route?  

At any rate- very cool.  Any chance we will be able to get out the knife and convert the 1.3 version to 1.4?

Thank you very much Gabriel, you offer incredible customer service!

I haven't ordered them yet, that would be really really great if you could.  Thanks very much.  You can email me at mattbechberger@gmail.com. 

You will need to pry the OLED very carefully, that double sided tape is very sticky. Try prying from all angles you can access.

Once you lift the display, try to remove the tape as much as you can and just put new tape over it. If you have not yet ordered the parts, send me an email, I can send you the TPS60403 and the tape.

Thanks Gabriel.  I suppose its possible, I was running the unit off of a 6V unregulated wall wart, using a 7805 to regulate the voltage to clean 5V.  Digikey has the part, I should be able to fix it.

Hi, your projects are very good. Can you explain this new project, give me more details please.

I have good news. Two popular requests will be possible in hardware version 1.4:

1) Connecting the Xprotolab to a PC will be possible using a UART to USB cable. Here is a preview of the PC application, although it is not doing much right now.
2) Firmware upgradable. Also, with the use of the USB to UART cable.

But one bad news is that I have run out of program space. No more new features can be added, at least until the ATXMEGA64A4 becomes available.

Hi. It looks like the -5V generator was damaged (TPS60403). This chip has a maximum rated voltage of 5.5V.
Maybe you accidentally applied more than 5.5V volts to the Xprotolab?

About the menu, if you see something that doesn't look right, please email me so I can check it out.

A Dutch leading electronics magazine "Elektor" has featured Xprotolab on their site: http://www.elektor.nl/nieuws/miniatuur-scoop-golfvormgeneratormodule-voor-35.1752608.lynkx   (in Dutch)   Jan.

One more : for your protocol sniffer - RS 485 oke i am aware that i also need a buffer IC for that but it is used a lot.

Keep up this great work :)

If you invert one of the channels, then activate CH1+CH2, you get the substraction.
