Hello all, I have a two part question. I need to test the responsiveness of some piezo sensors, and came across Xoscope [for ubuntu] an oscilloscope that uses a sound card (via /dev/dsp or EsounD) as the signal input. The Built-in mic on my laptop delivers an audio level reading to the scope. So far so good. Question:
1. "Buffer Hardware for xoscope"
Is it safe to use the mini inputs jacks on my laptop to probe an analog circuit with or without the buffer Hardware. See Xoscope here: http://xoscope.sourceforge.net/
NOTE: Buffer Hardware for xoscope http://xoscope.sourceforge.net/hardware/hardware.html
This post frames it nicely. http://sourceforge.net/projects/xoscope/forums/forum/23486/topic/1142171
How much voltage can I have at the RCA jack before my soundcard fries.
(I have read somewhere that the maximum inline of a soundcard is about 2 V, is this true)
2. "Processing and Mega 2560"
I trying to use arduinoscope with the Arduino Mega 2560.
port = new Serial(this, Serial.list(), 115200);
I don't get this with the ArduinoDuemilanove. Unfortunately I need it to run using the Mega 2560 as that's my spare at the moment.
