I have built a project from the Electronoobs YT channel, ( Component tester) but I cannot upload the HEX files. It is because the newest Avrdudess doesn't work for me. It just complaining to open any COM when I try to detect the board. I suppose, based on many videos I was able to copy the setting, that is not much, yes? COM port, baud rate, chip type ATmega328P etc...
What have I done so far to solve this out? Of course, research, a lot, but only common answers are out there.
I have tried 2 different PC/Laptop under Windows 10 / 11. (my biggest trust was, that something wrong with my laptop/windows etc. Well, it is not!)
I have tried many cables, as well as...
used different and new Arduinos like pro mini, nano, mega etc.
of course, I have changed all between computers, re-compiling the ISP programmer example.
I even installed that "libserialport" thing, that I have no idea what it is.
As you see I went through everything that I can think of but no success.
What could be the problem? I don't think so the new AVRDUDESS itself? Or is it?
Please give me some clue, because that drives me crazy
I just want to finish this simple project, and I am not able to upload this .hex files...
Thank you so much!
Select View > Devices by type from the Device Manager menus.
Open the "View" menu.
If there is a ✓ to the left of the "Show hidden devices" menu item, click on "Show hidden devices" to disable it.
Disconnect the USB cable of the Arduino board from your computer.
Take note of the contents of the "Other devices" and "Ports (COM & LPT)" sections of the Device Manager tree.
Connect the Arduino board to your computer with a USB cable.
Select Action > Scan for hardware changes" from the Device Manager menus.
Did you see any new device appear in the Device Manager tree after doing this? If so, please tell us where it is located in the tree and what it is named.
You can repeat steps 5-8 multiple times if you are not sure.
Well, I have tried almost the same, before, Scan for hardware changes etc. As then, and not now, nothing new come up.
As I mentioned, I have the same issue on other PC that is very interesting. Also 3 different Arduino have been tested... nothing changed... Avrdudess doesn't detect the boards.
But I am looking forward any other idea you have .... because that problem is too much for me
Thanks a lot! Realy!
OK, so this tells us that the problem is at a lower level than the Avrdudess application. It is either at the operating system level or at the hardware level.
Typically when the problem is at the operating system level, we would still expect to see a device appear in Device Manager, except in the "Other devices" part of the tree instead of in "Ports (COM & LPT)" as expected.
Typically when the problem is at the hardware level, we would not expect it to occur for multiple boards and USB cables.
It is possible that the problem could be in the USB hardware of your PC instead of the external hardware. Try plugging the USB cable into a different USB socket on your computer and then check if you now see a device appear in Device manager. Make sure the USB cable is fully inserted into the socket on the computer and the Arduino board (the socket on a brand new board can be unexpectedly stiff).
Thank you so much for your help but I was thinking a lot about this, and I didn't believe it was a USB, PC, or software issue. So I was thinking more... What I haven't done so far!?
I'm a "believer", which means I always list someone like you, like a guy on YouTube, "try to find the most professional" person, not the "playing kids". However, sometimes I am disappointing YouTubers for example. Here is this Electronoobs guy, who built this Component tester and it gives me a hard time now.
Let you know, and others maybe, the current problem has been solved by me.
It was the above-mentioned problem: I was truly believed others. Shouldn't do that.
BAUD RATE was the problem. Everyone in the videos shows 115200!
But my boards, most of them, are not original Arduino, (except MEGA).
So I was playing with it! Eventually, I am not sure now, but one Nano board was detected and uploaded the HEX files to the ATmega328p with 57600? Or less. I am not sure really.
The point is that has been solved, I just need to get working on this piece of shit, as it is still not working! The project itself. Now, I have a problem with the screens, but it is a different topic from here.
AGAIN: Thank you so much for your help! You were the only person who really helped, in this forum. NO one helped in Reedit, discord, and other forums. All the best for you!
