OSEPP Uno R3 Plus

[bashcommando]

I got a brand new microcomputer for Christmas(YAY!). However when following the tutorial it assumed that it was plugged into my serial port. But, I have a laptop, so I used a USB connection. What now?

Does this help?

d. Select the serial port: Tools > Serial Port

This is the serial port for the board’s built-in FTDI. If you do not know which one this is, you can find out by going into Device Manager > Ports (COM & LPT), and look for a “USB Serial Port (COMx)”

There is nothing that says COM ANYTHING in my /dev/ directory.
Output of

ls /dev/

I don't know if this is significant but the com ports in linux start with ttyS0 (that's ends in zero) and go on from there, the next one would be ttyS1.

Type "ls /dev/ttyS*" to see them. Just because there may be (for example) a ttyS3 file, doesn't necessarily mean that there exists a physical serial port there.

It won't work I try:

sudo python
import serial
ser = serial.Serial('/dev/ttyS0', 96000)

Then it gives me a error, I tried all the numbers from 0-3

You could try emailing the manufacturer or posting to their forum (which doesn't seem to have a lot on it.)

Is your board like the Arduino UNO? I connect to an Arduino Uno through /dev/ttyACM0 (can be ttyACM1 sometimes though). This is through a USB serial cable (Printer Cable).

Also, have you tried using the Arduino IDE? Probably works with that board too.

Did you happen to see the output of

cat /dev/

But it is like the Arduino Uno

I did. When the Uno is attached to the system the file in /dev should be created. You may also be able to create the /dev/file with makedev.

 

[bashcommando]

How do I use makedev?

mknod /dev/ttyACM0 c 166 0
