Features
Vertical (Voltage)
- V/Div
- AC/DC
- Offset
- Invert
- Probe divider / multiplier
Horizontal (Time)
- T/Div
- Offset
Trigger
- Voltage level trigger
- Trigger on rising / falling edge
- Single trigger / force trigger / trigger continiously
- Auto detect and track trigger level
- Trigger at fixed frequency / Trigger output
- External trigger
- Pretrigger (sample continiously then stop n samples after the trigger)
- Filtered trigger (low frequency / high frequency / number of pulses)
- Video trigger
- RS-232 trigger

Coding
Protocol
One byte each: C SS DDD... C = Code S = Size D = Data
Commands PC → STM32
- 0 0 4 DDDD - Set sample rate in Hz
- 1 0 5 D DDDD - Trigger mode & voltage
Commands STM32 → PC
Advanced features for the future
- Realtime view and control over IP by another computer
- iPad/IPhone view and control
- Web interface
