This tool provides everyday hardware makers the option to turn their Arduino Uno's into simple oscilloscopes.
- Operates on all 6 pins
- Triggering on arbitrary pins
- Triggering with positive or negative slope
- Variable sample rate
- Freeze frame investigation
- Max sample rate: 25.64 kHz
- Max Voltage: 5.0 V
- Voltage accuracy: 4.9 mV
To run, simply upload the code in the arduino/openscope folder to your arduino, and launch the processing application built for your system. Select your COM port from the dropdown at the right, and click "Connect." A green signal graph for pin A0 should appear on screen.
It should be noted that enabling more pins will decrease your sample rate. Since pins must be sampled one at a time, the Arduino will linearly sweep through the selected pins.
