// 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
