If you need a very cheap oscilloscope (for low frequencies) that has the look_and_feel of a real oscilloscope, this is the right page for you.
This is an evolution of the project lxardoscope.
Using the new firmware the sampling rate is 15Ksps dual channel or 21Ksps for a single channel.
I have used an Arduino Nano and one 1Kohm resistors between AREF and +5V: A0 and A1 are the signal inputs for the two channels.
Here is the code File:Lxardoscope 0.95.vfast.tgz.
In order to achieve the sampling speed, uart speed is 1M, samples are retrieved using interrupts and the
Enjoy.
