- Topic: Headless ResolutionYou Reply: No idea how to change this for Windows but on Linux you can set the resolution as a boot parameter upon startup so X11 runs at native 1080p resolution.
Why not try plugging in an HDMI cable without connecting it to anything ( or try crossing the video output pins on it ) and see if it switches to 1080p ?
The 1024x600 screen is the native graphics adapter running at default settings so you merely need to tell it to switch resolutions. - Topic: Win7 x64You Reply: I could definitely try it but I'm far too busy these days with programming other things.
Maybe one day I'll decide to do it. - Topic: LattePanda change logYou Reply: Much appreciated. Might I suggest you add this version comparison chart to the thread:
- Topic: Win7 x64You Reply: Quick FYI for this old thread, it's possible to install those drivers by simply porting them from Linux. ( It's open sourced and has every driver necessary for the LattePanda to function. )
Apart from that, Windows 7 doesn't support UEFI booting but can run in legacy mode with driver-sign checking disabled meaning you don't need a valid signature to load these drivers.
So if you're a skilled developer or even a mediocre C programmer with a fair bit of time on their hands, it's completely do-able for free. - You Reply: You might have a defective board or corrupted drivers. If you see that static at the bottom of the screen in the BIOS, more than likely it means your board's defective so you should send it to be replaced.
If however it's corrupted drivers, you should try reinstalling Windows and the drivers again ( follow the Github thread ) - You Reply: It's a weird line.
For me, using sketches that stress the Arduino's CPU ( Aka without sleeping in between -- long loops, intense tasks etc. ) will lock up the chip and thus require a reset to upload a new sketch. Depending on your sketch, that may be the problem.
Although since you said you're using the simple Blink sketch, no idea why it happens, you shouldn't need to do this everytime or maybe it's just a bug with the version of the software you're using ( Perhaps try updating it if you haven't already or switching OSs ? ) - You Reply: Depending on how you last uploaded a sketch, the Leonardo might have a bad program uploaded and it'd require you resetting it. ( Hold the Arduino Reset button )
While doing this you'll need to start uploading the sketch before it finishes initialization. That should fix the issue. If not, you'd probably need to reboot. ( Com port sometimes gets locked up. ) - Topic: Auto Sleep and WakeYou Reply: Don't think it's possible to actually make the system wake up automatically ( Unless it supports some form of Wake-On-LAN ping. )
Might I propose an alternative though ?
- Try switching the power-plan to Low Powered mode when you don't need work done.
- Stop some power-hungry services. ( Windows Update etc. )
- Turn off the WiFi and Bluetooth devices.
- Kill any unnecessary programs.
Simply revert these when you need to go back to normal. Should decrease the power draw even further. - You Reply: In addition to the above ways, there's several other ways to start a program on Windows, any version.
The most common ways are usually:
1.) Creating a shortcut to the Startup user folder. ( %appdata%\Microsoft\Windows\Start Menu\Programs\Startup )
2.) Create a shortcut to the global application start folder. ( C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup )
3.) Installing a service to run the command. ( Far more complex but guarantees the program runs regardless of which user is logged in. )
4.) Adding a registry key containing the command to run in one of these locations:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run - You Reply: Yes, as a matter of fact I've noticed its lack of ability to constantly "spit out" information which also is interpreted as the end of transmission.
The solution for me at least, was to increase the baud rate and set up a syncing-algorithm that polls the device in intervals for data. - You Reply: Ah, I've responded, it's a simple mistake I once made too. Hopefully my solution also solves your problem.
Cheers. - You Reply: The LattePanda has an Arduino Leonardo, not an Uno.
Select the Leonardo and it should fix the problem. - Topic: Help Lattepanda not bootYou Reply: Yep, that's exactly what I did to brick my first LattePanda. I didn't realize why it suddenly stopped booting, even to the BIOS at first till I did some research.
It turns out, the Intel Atom x5-z8300/8350 doesn't support dual-channel RAM. ( No idea why the BIOS even supports this option. )
Since it doesn't support dual-channel memory, you basically need to re-flash the BIOS to fix it since the settings are stored in flash-memory.
@LattePanda I really hope you could contact the BIOS developers and have this option removed or at least have a warning to NOT change the memory to dual-channel mode.
Can't imagine the number of clueless users who accidentally turned this on in hopes of getting a speed boost. ( *cough* me ) - You Reply: The LattePanda doesn't have any built-in RTC batteries, to actually maintain time, you'll need to either keep it powered or solder on an RTC battery to specific pins.
These are the polarities. ( Taken from the forum. )
- Topic: Memory rises problemYou Reply: You should open up Task Manager and locate what's consuming most of the memory.
To be honest, 2 GB isn't nearly enough RAM to properly run Windows 10 at this point, you should turn off all unnecessary services you don't use as a measure to counteract it filling your RAM. - You Reply:

Deleting any system file really is a bad thing. You should restore it.
To solve this problem i deleted the wuauserv from windows 10.
Is that a bad thing?
@OP I recommend if they're going to be connected to the internet and you don't want them updating that you add a hardware-level firewall and restrict access to all Microsoft based IPs via a protocol rule.
Optionally, you could just block all outgoing traffic via the hardware-firewall and allow only the ones you need when it is connected to the Internet. - Topic: Problems with digitalReadYou Reply: Might be wrong but I'm pretty sure Pin #7 is an analog pin.
- Topic: Upgrading Win 10 Home to ProYou Reply: Completely possible, yes. The Windows 10 version is just like any unlicensed Win10. You just need a key.
- Topic: USB output currentYou Reply: I'm fully capable of running an external HDD ( no external power ) directly from my USB 3.0 port and that draws 2.5W @ 500 mA fine.
This also includes me using WiFi, Bluetooth, having a USB mouse/keyboard w/ LED lights on them all on simultaneously.
So the LP is more than capable of doing what you want. I suggest you use a beefier power supply for the unit.
My power supply is a 5V, 3.5A PSU ( For a maximum of ~18 W ). I suggest you get something similar and you should be more than fine. - Topic: wifi issuesYou Reply: Clearly a Wifi driver issue. I'd recommend you try:
- Tweaking the WiFi settings.
- Reinstalling the WiFi driver.
- Reinstalling Windows. ( Probably will lead to the same result as #2 above. )
