Hello,

I am reading I2C data from my IMU chip mpu9265 in Arduino software, at baud rate 115200.
Everything works well, the serial monitor shows 9 values (3x3axis) at the same time, constantly changing.

Now I open Pd, create a comport object and set the appropriate baud rate 115200.
Of course, comport outputs odd data that is not exploitable if not unpacked.

So here come my questions :

• How to 'unpack' the data from comport in order to see the 9 different values ?
• In the Arduino monitor, the 9 values are separated by a space, ending by a carriage return. Does this affect the data reception in Pd ? Should I collect the raw data in arduino and convert it in Pd ?

I am not sure OSC can be used here.
Thank you in advance for help !

Of course unpack doesn't work, acting like it receives the data stream like a value and not a bundle. Maybe I am doing something wrong ? Here is a screen capture of my patch,
where unpack shows the same output value as its input, in the 1st outlet.

Check the [serial_print] abstraction here https://github.com/alexandros301/Arduino_println_parseInt_to_from_Pd
It can distinguish values separated with a space or a comma. I guess on the Arduino code you use Serial.print() and eventually Serial.println() right? This is the way this abstraction works. Check the corresponding Arduino sketch that come with the abstraction and its help patch.
If it's not working come back with more details (like the Arduino sketch for example).

BTW, the second outlet of [comport] will not give the data you're looking for, but info about the connection (its state, the baud rate etc.).

Yes I use Serial.print() instead of Serial.write().
This is a very nice set of patches that you provide. Wonderful [serial_print] object helped a lot.
However, it only works when I separate my values with commas (even if i tick/untick the box).
But I can get all the values I expected. Very helpful, thousand thanks !
