I am in the process of building a synthesizer using Arduino Uno and LINX. I am generating a square wave using "Digital Write Square Wave" (25Hz-6kHz) and I can see a nice wave on an oscilloscope. After manipulation via hardware filters, op-amps etc. I want to read back the manipulated wave to see how it's changed. I have been reading from AI0 through LINX but I cannot see the wave, just a "high" voltage reading.
Is there any way to read these waves using LINX, etc. or is this a limitation of serial comms and I should just use a 'scope? I have thought about using the internal memory of the Arduino to read the wave then pass it to Labview but I have no idea how to do that or if it would work.
