hello,
I have very small experience with arduino and I don't havew now one, but from my knowledge:
doesn't it depend, what kind of info is the arduino sending? Do you know what sketch is uploaded to arduino?
The difference is that if arduino is sending the information wit Serial.print it is sent to serial port as string (or text), so you can do
cat /dev/ttyUSB0
in terminal and see readable output
if it is sent with Serial.write , inf is sent as binary bytes.
I assume, similarly csound's serialPrint assumes that string is coming in and serialRead reads the stream as binary bytes.
If Arduino sends '300' with print, bytes '3','0','0' etc are read with serialRead. That's why the porridge.
In short: if you get expected result with serialPrint, stick to it!
(although Serial.write in arduino and serialRead in csd should be faster),
hope it helps.
