RoadTest Thread for LattePanda 3 Delta

As far as I know, *ALL* LattePanda boards are shipped with the eMMC imaged with Windows on it ... regardless of the SKU, as I previously had a non-Windows LattePanda Delta shipped to me that way.

But those who don't have a license will find their board is "Unactivated" when they check their activation status and won't be able to activate it without buying a product code.

Once the LattePanda 3 Delta was up and running W10, found Arduino IDE was part of W10 install, AND that install included the boards manager for the "LattePanda Leonardo", had I had not already prepared a list of a dozen apps needed for the 1st test project, I wouldve started wiring up LEDs and servos :-) Definitely the Arduino IDE will get some action. 

Another big surprise & point of interest - the first app installed by me to the LattePanda3Delta was Google Chrome, to have the LP3 web browser match my laptop. I was going to do some latency observations as part of the road testing, but it was already plainly obvious the LattePanda3 is faster than my laptop. It has 8Gb memory, my laptop only has 4Gb, both using 2G clocks, with LP3 being able to get to 2.9 Ghz. Wow, it was noticable.

Thanks Chris - In moving forward installing & setting up apps on the LattePanda 3 Delta, I banged into the license activation limitation while setting up an external USB sound card, see the screen capture of Settings/Sound message. I'm not to the point of knowing if it causes an operational problem yet to my project.

After digging more into the W10 activation topic should I choose to upgrade to solve the warning message, the Latte Panda 3 Delta W10 activation screen gave a dark foreboding message in the SETTINGS/Activation screen. 

Clicking Troubleshoot, the final solution recommended is to contact my system administrator.

Referring still to the SETTINGS/Activation screen capture, when CHANGE PRODUCT KEY is selected , a pop up says to find the product key provided by the vendor. It doesnt like all those XXXXXXXs in the product key seen and hits a brick wall.

Should LattePanda be contacted for more followup info, or is this where the product road forks and I need to deal with Microsoft directly to buy W10 pro ( on Holiday Sales for $35 rapidly shrinking USD ) 

OK thanks, found more on the topic. None of the personalization settings are available when unactivated, like setting the desktop screen background, and sound settings. When using VNC to remote in to LattePanda,the background goes black.  

I learn alot on every Road Test. I just got lucky this time, was selected for only 1 road test last year. Best of luck , I hope you snag your next one. 

srutledge -  cstanton    Sorry to drive the blog crazy with questions, hopefully saves time for other Road Testers.

A short "blink" program was loaded to the onboard LattePandaLeonardo using Arduino IDE 1.8.16, it worked OK first try. 

The Latte Panda 3 online documentation doesnt include further info on Arduino IDE programming or examples for interfacing the Leonardo to Windows10.

Latte Panda V1 online documentation does list programming Arduino, requiring Visual Studio 2017, and a Latte.Panda.Firmata  library. However , the documentation lists only typical GPIO operations, I'm thinking thisVersion 1  documentation does not apply to LattePanda3Delta with LattePanda Leonardo.

Please advise if there is LattePanda 3 Delta Arduino Leonardo Examples and documentation pertaining to W10 interfacing. I could not find any surfing the web.

This's a forum, it's totally meant for questions! You can even start a new thread if you feel it should get its own attention.

I'm sure we can have a look. From what I recall, in Windows 10 I simply used the Arduino IDE, selected the correct COM port and Board type, and uploaded programs that way. It's not clear by your reply here, but is that how you're also attempting to do it?

I think he's trying to use the GPIO pins on the Arduino from an application running on the host, in which Firmata is acting as a "bridge" protocol, receiving instructions over USB virtual COM to enact changes in GPIO. Not exactly the best way to work from a speed perspective, but may allow you to overcome some limitations of the Leonardo-like AVR 8-bit controller.

There may also be broken out GPIO that are part of the actual host that don't need to be accessed via the Arduino side as well, but perhaps more dangerous to use ...

I think more clarification from robogary's required either way, including the intended setup (are we trying to program the Arduino from another computer, or the lattepanda itself, for example?)
