key.py held every key for 2500 ms, on the assumption that guest time runs fast during delays so a press needs a long wall-clock hold. That is wrong for this path, and it is why the keypad looked dead. The two SysTick mechanisms are separate. poll-boost accelerates counter *reads* so SYSTICK_DelayUs converges; it does not speed up interrupt delivery. Interrupts drive SysTick_Handler -> gNextTimeslice -> APP_TimeSlice10ms -> CheckKeys at close to real time, so the firmware's thresholds hold in wall clock as written: 20 ms to register a press, 400 ms to count as held. 2500 ms is ~250 ticks, six times past the long-press threshold, so every press was dispatched as a hold. MAIN_Key_MENU acts only on a short release and returns early when bKeyHeld is set, so nothing happened. Confirmed by reading gDebounceCounter mid-hold: 317 after a 3 s hold, which also proves the timeslice was running all along. Now HOLD_MS=200 and LONG_HOLD_MS=900. Verified with screenshots: the menu opens and UP/DOWN move through it. Also here: - Drop the three TRACE fprintfs. They fired on every keypad poll and buried the console; the matrix is confirmed working. - Drop a redundant forward declaration of py32_spi_xfer_byte, silencing the only build warning. - Document the real remaining gap: power save (~6 s after boot) stops the keypad scan and the model does not wake from it. Includes the two dead ends already ruled out by experiment, so nobody repeats them. - Add README screenshots captured from guest memory.

"""Press keys on the emulated radio through its QMP socket.
|
|
|
|
The keypad model exposes a "press" property: writing a key name holds that key,
|
|
writing an empty string releases it. The firmware debounces over several 10 ms
|
|
polls, so a press has to be held for a while to register -- see HOLD_MS.
|
|
|
|
Usage:
|
|
key.py MENU # one short press
|
|
key.py MENU UP UP EXIT # a sequence
|
|
key.py --long F # long press
|
|
key.py --list # show key names
