For many developments an Oscilloscope is much needed. And when it comes to pricing it is not a really friendly choice to buy one.

We have a lot of options with the Microsoft Windows which can make the Arduino solve the purpose by displaying input signals on your computer.

But when it comes to Linux, with immense efforts one can find only a few options which may or may not work on every machine.

So here's a solution for this. Arduino Oscilloscope.

• An Arduino Clone (Currently only arduinos with Specific Serial Descriptions are supported)
• Python 3.x.x
• Creativity to help this project grow

Framework Used: Arduino (For the sake of simplicity)

Use A0 pin only with following code.

Flash following code on your MCU:

void setup(){
    Serial.begin(115200);           // Use any Baud Rate you want.
                                    // Make sure you change the
                                    // baud_rate in line 94 in:
                                    // src/main_frame/frame.py
}

void loop(){
  double probe_val = (double) analogRead(A0) ;
  double val = probe_val / ((double)1023) ;     // Step1: Step Normalization
  val = val * 5;            // Step2: Value Normalization
  Serial.print(((String)val) + " " + (String) (micros() - start_time));
  Serial.println();

}

Feel free to use any other framework of your choice. Make sure you normalize the input ADC data as mentioned above in the code.

• Download this Repo and Extract it to a location of your choice
• Open a terminal in the same location
• Enter Following commands:

sudo chmod +x oscilloscope.sh setup.sh
sh setup.sh

• This will create a Desktop Shortcut for your application
• Double click on it and 'Trust and Launch' the application

• Minimum Input Voltage: 0V
• Maximum Input Voltage: 5V
• Sampling rate: O(16 MHz)

• Memory Management Thread added
• Support for Arduinos with the Serial Manufacturer description containing the string "Arduino"

If you find the Manufaturer Description for your device's Serial interface, Add the Manufacturer Detail to the SUPPORTED_DEVICES list from following file location:

src/main_frame/SerialInterface/serial_ports.py

Don't forget to add a fork to improve the support for devices.
