I attempted to run the example hello world and got a long script of information that doesnt constitute the command println("Hello World ). The return information that I recieved was this:

Resetting USB to switch back to runtime mode

my question is whether I have installed the hardware/IDE properly on my computer or whether I am missing something. I was expecting that string to be returned within the IDE but maybe I have it all wrong. Any help would be great!!

trey2324 - please paste the code (if its not more than a page), or a link to the code (and paste the code at pastebin, gist, i.e. somewhere we can see it).
Please also look at the posting guidelines http://forums.leaflabs.com/topic.php?id=994
It is often helpful for us to know the version of the Maple IDE and operating system that the host PC is running

A common problem is caused by the host PC switching between interpreting the Maple as a USB DFU device, and a USB serial device. This can take so much time that the first few strings can be lost by the host. There are several threads with advice on how to minimise the impact of that problem. When just using the program to test the USB communications to the host PC, then a fix is to print a message from loop(), say every second.

Have you been able to upload the 'blink' program?
That is the usual embedded equivalent of 'hello world'. Blink is a useful test to ensure everything else is working. You might change the value in the delay(1000); to something visibly different, e.g. 100 to ensure you are seeing the effect of loading the program.

void setup() {

}

void loop() {
SerialUSB.println("Hello World!");
}

is the code I used which is one of the provided examples. The board that I have is the maple r5. The IDE being used is v 0.0.12 (arduino) and it is being ran on a windows 7 OS.

I was able to run the blinky program for the internal LED and change it from 1 second to 3 seconds and it worked fine, so communications are good. I was just wondering why i was unable to get the above code to println.

Thanks for your help

trey2324 - I don't use Windows, so I can't help much more. Windows is often a source of problems.

I don't think it'll make much/any difference, but I would slow the printing by doing a delay:
```
void loop() {
    SerialUSB.println("Hello World!");
    delay(100);
}
```
When the 'Hello World!' program is running, can you open the serial monitor? Does it find the Maple?

(Full disclosure: I am not a member of LeafLabs staff.)

I tried the delay up to 5 seconds (5000) still no change. I believe that I may be the fact that the IDE is being run on windows 7. I am unable to open the serial monitor during the upload process. Do you know who i can contact in regards to the problem?

Thanks

Hi there trey, are you using 32-bit or 64-bit Windows 7? Can you open Device Manager and find out what Serial port is being used by the Maple? Use another program like putty to open up the Serial Port if it's available with a baud speed of 115200. Is there still no response? What board option is selected?

>> ... I am unable to open the serial monitor during the upload process...

Just a quick question : are you trying to open the serial monitor during the upload? It doesn't work like that. You'll have to wait until it's uploaded and the maple has been reset before opening the serial monitor. Leave the delay at 100.

>> I was expecting that string to be returned within the IDE but maybe I have it all wrong.

Just to clarify, the "hello world" does not appear in the IDE. The messages you original posted above ^ are just the program being compiled and uploaded to the Maple. Once the program has been uploaded it runs forever. No need to upload it again. "Hello world" will only show up in the serial monitor (or another serial monitor type program).

I had the baud rate set at 9600 and I changed it to the 115200 rate that you instructed. I opened the serial monitor after the program was loaded to the board and found that it is running. Now I just need to stop it from being a infinite loop (thats coding though) thank you all for helping me to understand how this IDE operates!

I also found that the board needs to be in prepetual bootloader mode in order to take this program on my 64-bit machine. The strange thing is that the blink program seems to run just fine in bootloader or in regualr mode the com port 4 recognizes the board.
