Compiling

For compilation, following packages need to be installed:

• golang
• SDL2-devel
• SDL2_ttf-devel
• fftw-devel

The packages can be installed running command: sudo dnf install golang SDL2-devel SDL2_ttf-devel fftw-devel

Additionally, you need to combile go libraries used by analyzer:

go get github.com/veandco/go-sdl2/sdl
go get github.com/veandco/go-sdl2/ttf
go get github.com/jvlmdr/go-fftw/fftw

Finally, the analyzer can be compiled running command: go build -o analyzer analyzer.go

Runtime dependencies

For running the analyzer, following packages need to be installed:

• SDL2
• SDL2_ttf
• fftw

The packages can be installed running command: sudo dnf install SDL2 SDL2_ttf fftw

Configuration

Create config.txt containing information about tones. The easiest way to obtain information about the tones is by running the analyzer in debug mode: ./analyzer -debug, emitting the tones and capturing peak information (together with the value of the peak). The capturing can be paused at any time by pressing space.

Running the trigger

./analyzer | ./trigger.py --keep-reading GBAD echo HIT
