TOscilloscopie is a custom FiveWin/Harbour control designed to simulate a digital oscilloscope.
It can display real-time waveforms such as sine, square, triangle, ECG, FFT, noise and glitch effects using double buffering for smooth rendering.

The class supports:

• customizable colors for background, grid and waves
• horizontal scrolling and real-time updates
• multiple visualization modes
• animated signal generation with timers
• GDI drawing directly on memory DCs for better performance

It is useful for audio visualization, MIDI monitoring, signal analysis and modern UI applications written in Harbour + FiveWin.

Easy syntax

@ 10,10 OSCILLOSCOPE oOsc ;
      SIZE 930,300 ;
      OF oDlg

   ADD CHANNEL TO oOsc ;
      COLOR CLR_YELLOW ;
      PEN 2 ;
      TYPE OSC_TYPE_SINUSO

 ADD VALUE TO oOsc ;
      CHANNEL 1 ;
      VALUE nSin

TOscilloscopie is not just a graphical effect control.
It can be used to create real-time waveform visualizers, audio analyzers, electronic signal simulators and educational applications.

Some possible uses:

• Audio waveform visualization
• Oscilloscope simulation for schools and laboratories
• MIDI activity monitor
• FFT / spectrum analyzer
• Real-time serial data visualization
• Arduino / ESP32 sensor monitor
• Industrial data plotting
• Scientific signal analysis
• ECG / biomedical signal simulation
• Retro synth and music applications
• Debugging serial devices
• Educational electronics software
• Waveform generators
• CSV / WAV file visualization
• Real-time monitoring dashboards

The control supports:

• Multiple channels
• Independent colors and pen sizes
• Different waveform types
• Horizontal scrolling
• Configurable grid
• Center reference lines
• Vertical and horizontal measures
• Real-time updates
• Script-based waveform generation (on working)
• Custom waveform rendering methods

Possible future extensions:
-scripts

• Audio input support
• WAV playback visualization
• USB/RS232 hardware integration
• Trigger system
• Zoom
• Data recording
• Screenshot export
• Signal math functions
• Real-time FFT

One practical use of TOscilloscopie is real-time visualization of data coming from a COM/RS232 serial port.

For example:

• Arduino sensors
• ESP32 devices
• Temperature sensors
• Voltage readers
• PWM generators
• Industrial controllers
• Laboratory instruments
• Serial debugging tools

The device can send numeric values through the serial port:

45
48
50
55
60

and the oscilloscope can display the signal in real time using:

ADD VALUE TO oOsc ;
CHANNEL 1 ;
VALUE nValue

This makes TOscilloscopie useful for:

• Electronic laboratories
• Technical schools
• Automation projects
• Audio experiments
• Sensor monitoring
• Educational demonstrations

The class can also be used to visualize data coming from:

• WAV audio files
• CSV files
• MIDI events
• Real-time generated signals
• External scripts
• USB virtual COM devices

Example architecture:

Sensor -> COM Port -> FiveWin RS232 -> TOscilloscopie

The control can therefore simulate a small software oscilloscope entirely written in FiveWin/Harbour.
