I am trying to write data from Pd to Arduino. Has anyone used
[comport] to write out serial data before? Any example patches? I
can only get TX_OVERRUNS errors.

used it fine many a time,
I did get weird TX errors on one particular machine, and not since...
It was a fedora core2, on a asus p4c800 machine.. I never figured out why, I may have sent a message to the pd-list about it way back...
What OS/machine you doing this on?

Sorry for the super brief message, I was being forced out by the
museum security as I was writing this. Its on Windows that I am
doing this. Receiving data from Arduino works great, but on the same
connection, anything I send gives the error, even just clicking one
message box like [56(
But I am not sure its not in the Arduino code yet.

Just sending numbers into comport works fine .You just have to make sure to open the correct serial port to avoid the TX_OVERRUNS errors, that is the one you assigned in the arduino MENU:TOOLS: serial port...
|devicename /dev/tty.usbserial-4B32[ or something similar.
hope that helps, adrian

If CTS/RTS pins aren't connected properly then the computer's UART might be supposing that the device is not there and so it will accumulate data until the buffer overflows, a situation which gets trapped and becomes a TX_OVERRUNS.

No data ever gets thru when writing to the serial port, and on
reading works fine as it is. So I don't think CTS/RTS is required.
Its not used on GNU/Linux or Mac OS X.

I am here working with David Cuartielles and some of his students, so
I think he can write good Arduino code ;). The network is down, and
I am on my Mac, so I don't have the exact code.
We've tried a number of different programs and setups, and a couple
different boards and computers. Even the basic program which just
relays the data received back to the serial port doesn't work. Data
is not coming out of the serial port from Pd.
Have you successfully written to the serial port on Windows using
[comport]?

I'm on Windows XP and we use [comport] to let pd communicate with a motion tracker. We use a modified [comport] object made by IEM guys. You can download our version from http://iem.at/~majdak/download/pd/ It tested and stable for Windows 2000/XP.

I don't think he did. I have been debugging [comport] writing on
Windows, and got it working. I'll take a look at this version and
assemble all of the changes and commit it. Wini said it was ok for
me to commit my Mac OS X changes to comport.c, so I think it should
be ok if I commit these Windows changes too, right?

Piotr,
It looks like you properly implemented the asynchronous writing/
OVERLAPPED stuff, but you also changed the comment characters from /*
*/ to //. That makes it quite hard to read the diff output.
Could you create a diff file of only the relevant changes against the
CVS version?

ola,
i think David and Alex did some succesful use of Arduino and pd on windows and linux in the Arduino workshop they organised in la hangar, bcn. ( we had 4 working in the pd workshop we did last month ).
well, in any case, the contacts are :
alex posada ( www.nice-noise.org ) : alex@nice-noise.org lluis gomez i bigorda ( www.artefacte.org ) : lluis@artefacte.org
if that can help.. i never programmed arduino myself..
saludos, sevy

I am pretty sure I have found the problem:
#ifdef WIN2000 0, #else FILE_FLAG_OVERLAPPED, #endif
By default, this object is compiled with the FILE_FLAG_OVERLAPPED
mode, which enables asynchronous writing to the serial port. But
none of the Windows code is written to use the OVERLAPPED struct,
which is required when in async mode. Therefore, no data gets written.
But there is a exceedingly simple solution: remove the WIN2000 hack
all together and just use with sync mode, which is what the code is
doing anyway. But I don't have a Windows machine to test this on
right now, any volunteers?

I have successfully written on the serial port to the Arduino board from PD . Some tips:
- connect the board before running PD (or the comport external)
- close the Arduino IDE before running PD
- is their a security/permission issue where you can read the
(usb-serial) driver and not write it?
- are you using the USB version of the Arduino board?
- setting comport with the proper settings?
- do you get any error messages once you start comport?
