// Color bitmaps generated with:
// Gimp image > indexed colors (16), then "xxd -i *.bmp"

// Note about available RAM:
// Check what ends up in the BSS section by looking at the map files !
// Use constexpr where possible or make sure const are in .cpp files, not headers !

// Note about messages:
// There can only be one message handler for one kind of message at once
// If an attempt is made to register a second handler, there's a chDbgPanic "MsgDblReg"

// Note about matched filters: see proc_sonde.hpp

// TEST: Goertzel tone detect
// TEST: Menuview refresh, seems to blink a lot
// TEST: Check AFSK transmit end, skips last bits ?
// TEST: Imperial in whipcalc

// BUG: Console lock-up if first string to be printed starts with escape character ?
// BUG: (Workaround ok) CPLD-related rx ok, tx bad, see portapack.cpp lines 214+ to disable CPLD overlay
// BUG: SCANNER Lock on frequency, if frequency jump, still locked on first one
// BUG: SCANNER Multiple slices
// GLITCH: The about view scroller sometimes misses lines because of a race condition between the display scrolling and drawing the line
// GLITCH: Start of tx using ReplayThread plays a small bit of previous transmission (content of 1 buffer ?)
//	See fifo.reset_in() ?

// FIXED: Update button in signal gen doesn't work for shape change
// BUG: Signal gen noise shape doesn't work
// TODO: Continue acars receiver. See matched filter, probably doesn't shift the spectrum correctly

// TODO: Make CTCSS display only when squelch is opened
// TODO: DCS decoder
// TODO: Increase resolution of audio FFT view ? Currently 48k/(256/2) (375Hz) because of the use of real values (half of FFT output)
// TODO: Move Touchtunes remote to Custom remote
// TODO: Use escapes \x1B to set colors in text, it works !
// TODO: Open files in File Manager
// TODO: Ask for filename after record
// TODO: Super simple text file viewer
// TODO: Clean up ReplayThread
// TODO: Cap Wav viewer position
// TODO: Adapt wav viewer position step
// TODO: Use unit_auto_scale
// TODO: Remove make_bistream from encoders.cpp, too complex, stinks. bitstream_append should be enough.
// TODO: Continue work on proc_afskrx_corr, see python script (it works !)
// TODO: De bruijn sequence scanner for encoders
// TODO: FILEMAN Move files
// TODO: Use separate thread for scanning in EPAR TX
// TODO: Make freqman refresh simpler (use previous black rectangle method)
