USB on arduino side ?

Hi all,
I just seen that there is one USB port on Genuino 101 board alone.
Is this USB port exist on arduino side in UDOO ULTRA Board ?
If YES, how can i used it and where is connector?

Arduino 101's USB port in UDOO x86's implementation is internally (exist only in PCB traces)
connected to Intel Braswell's USB port #3 and not exposed.
It is used as Arduino IDE (x86 is the master) communicating with the Arduino device's command-n-control channel (as serial COM port.)

 

And if you want to connect an external USB device to the Arduino 101 to exchange data with serial protocol you can attach a TTL-to-USB device to pins 0/1 and talk to it with Serial1 object in the sketch. https://www.arduino.cc/en/Guide/Arduino101#toc12

 

OK,
I already use Inside USB port and outside uart genuino port.
I will find another solution.
Thanks

 

I tried to use SoftwareSerial.h librairy but il doesn't work in my case, because i have a lot of gpio interrupts and full duplex on uart...

 

Ahh.... That tiny Intel Curie needs a break.
Probably using a more powerful external Arduino to do the heavy lifting/share some burdens.
(I suggest the super cheap STM32F103 based solution. Mega2560, or Due are also fine.)

 

Not possible for me, I used UDOO ULTRA board with genuino 101 embedded ....
I tried too NeoSWSerial lib but it doesn't work with my MCU !!!

 

You have to use CurieSoftwareSerial. You can find that in the Arduino IDE for the Curie. Do not use the normal Software Serial.

Yes I use that library, but after any minutes, uart stop to work without know why ???

 

What uart? The build in one? Or the one you are creating with CurieSoftwareSerial?

 

The one i created with CurieSoftwareSerial. But for this test, i didn't use interrupt, only this virtual uart in Rx ....

 

Another test without CurieSoftwareSerial lib but replaced by uart build in one work fine.

 

I tried with less speed on virtual uart (pin 9 & 10) , i send a string with 32 characters all 100ms.
At 19200Bds, worked ok during 23'
Now i trying at 9600Bds ...

 

Idem, virtual uart stop working at 20'

 

I don't understand, when i add CurieSoftwareSerial, only SoftwareSerial.h file is added !!!
It's the same library that SoftwareSerial choosed !!! No difference !!!
