To compile and install

cd flipperzero-firmware/applications_user
git clone https://github.com/anfractuosity/flipperscope.git
cd ..
./fbt DEBUG=1 VERBOSE=1 fap_scope
./fbt launch_app APPSRC=applications_user/flipperscope

Provide signal to pin 16/C0, with a voltage ranging from 0V to 3.3V.

Press the 'ok' button (button in the centre of joypad) to pause/unpause the waveform display.

Demo showing three different waveform types from a signal generator.

Measurements

• Measures frequency of waveform in hertz
• Measures voltage: min, max, Vpp

To Do

• Voltage measurements for max/min of waveform seem a bit off currently, need to investigate further
• Customisable input pin
• Trigger type mode
• FFT
• ...

Inspiration

• For GUI menu system, used code principles from weather station and signal generator apps
• STM32 DMA example
