Serial Monitor issues

Hi,

I have some issues with the Serial Monitor. The program writes to the port (I write directly to serial port for debug purposes), but sometimes I dont get the output. Strangely I can upload the program fine, but the output is not displayed. I the unplug the device from the USB cable, try this and that and suddently it works  Undecided.

It is an issue with AtmelStudio, or is the problem on my chair ? Auto Re-Connect is True.

Thanks

We can do some more testing. 

1)
Are you using print() or println()

2)

Uploading with or without debug?

1) Both Serial.print() and Serial.println

2) Right from the program, I don't use the Debugger *sight*.

Tried it, afterward I had to close the monitor window and open it again.

Now it seems to be Ok. I don't always looks at the monitor window, and for some time AtmelStudio is minimsed or under another program window. Could that have an impact on the monitor window ?

I am in the hardest part of my development. To sum up, two devices talks to each other via XBees, and I look at the output window of the remote command wich use a different tool. Thing is I don't know wich devive fails (or both). Most of the time when I get back to the AtmelStudio monitor, it does not wotk  Cry.

I tried agin to send the AS monitor window behind, send commands to my device and brought back the window, it still works.

Hum, may be the auto-reconnect has to do with my issues, can't tell for sure.

Giles, if you are using a different app to use serial and have reconnect switched on it should be okay but maybe causing this issue.

Please don't use auto reconnect for a few days and let's see if this settles down. Auto reconnect is q relatively new feature, maybe it should default to off now that we have any easy checkbox on the serial window.

@drpeej did you try untick and then tick the connect box to close and re-open? with or without auto-reconnect? please create a new thread so we can discuss this more clearly. thanks!

Tim,

each of my development tools uses a different serial port, I don't switch from one to the other.

Is it me or does Windows have a hard time dealing with peripherals.

As for serial ports, I simply HATE THEM Angry whether on a PC or any other device.

I will leave auto re-connect False for a while.

Thanks, okay separate ports should have no affect on each other.

Let's see what happens with re-connect off, look forward to hear results

Hi Tim,

no special issues with auto-reconnect disable, except that each time I disconnect and reconnect the board from the port, I need to reset the connection  Wink.

I just downloaded the latest version, I will re-enable auto-reconnect, and clean up all the Serial.print() calls to make room for using your debugger.
