Apologies if I've posted this in the wrong place but I thought I should mention it.
I have been using Processing 1.n.n for a year or so to read data from a Junsi Celllog 8S (a cheap and cheerful battery cell voltage monitor). This has worked fine.
I recently updated to Processing 2.0.1 and the sketch stopped working. It was "reading" the data but it looked like the bit rate wasn't being set as the output was garbage. I binned 2.0.1, downloaded and installed 1.5.1 and it was OK again.
The Cell Log uses a bit rate of 128000 (which I set in the serial declaration). I wondered if in 2.0.1 this parameter was not working and the port was just defaulting to 9600
