Oscilloscope circuit and PCB

The circuit diagram for the oscilloscope

The circuit:

• S1-S2-S3-S4 is the pushbuttons for setting of the oscilloscope
• S1 The main menu
• S2 curser up
• S3 curser down
• S4 back (remove menu from the display)
• S2 double function - push S2 when the menu is NOT active - this is the new auto seting

• The connection for the attenuator module is not used in this design
• Display control - display intensity set by ESP32 PWM port
