Hi guys, this is my first post. I hope I'm putting it in the right place.
I'm trying to connect an arduino mega to PD on windows 10, but when I select the correct port through pduino, I get a series of RX ERROR reports in the console, then a pause, and then a continuous stream of similar errors. Neither analog or digital inputs work, but I can pulse the built-in LED ok. Everything seems to work ok for me on my win7 and XP machines.
I've read that [comport] was incompatible with win10, but that it may have been updated since then. The most recent version of comport.dll that I have found is from May 2015, which is before win10 official release.

Have you experienced this issue? Thanks for any help!

The author of the object was following conversations about it on Pd's mailing list, and he might have released a version after this issue made its appearance, I'm not sure though.
Search the mailing list archives, you'll might find a solution there. Does it work OK with the Arduino IDE?

Hi, I did have a search through the mail archive before I posted. But met dead-ends or info that went over my head. it seems like a fix was found here:
https://www.mail-archive.com/search?l=pd-list@lists.iem.at&q=subject:%22Re%5C%3A+%5C%5BPD%5C%5D+comport+rxerrors%22&o=newest&f=1

I found more recent builds here, but not recent enough, and they didn't resolve the issue:

Although some search results are dated 2016, the most recent version of the comport.dll that I've found is from 29/5/2015 (two months before Win10 official release).

I'm a novice arduino user, but things seem ok in the IDE. Can see board info, upload sketches ok.
As a semi-functional workaround, I've got the arduino talking to Processing now, and sending OSC to PD. But I think the Processing Arduino library is limiting my Mega to Uno pin totals (0-5 analog, 2-13 digital), and is pretty heavy on system resources, causing lags in PD.
So Processing is handling the serial data ok on Windows 10, but I'd prefer to be able to use [comport].

I guess it's better you send to the mailing list as Martin Peach (the author of the object) is very likely to see your message and respond.

It's a new laptop, and after fully updating windows 10, [comport] seems to be working! (It looks like I got some new USB drivers).
Serial data is now being received by pduino.
