VCStat - Raspberry Pi vital signs for AROS (native Zune window,
data straight from the VideoCore firmware).

Main window:
 - CPU (SoC) temperature with gauge
 - core and SDRAM voltage
 - real ARM clock speed
 - power status, now and since boot: under-voltage, frequency
   capping, throttling, soft temperature limit
   ("since boot" = the lightning bolt condition, even before
   VCStat was started)
 - refresh every 1-30 s, no CPU use between readings,
   paused while iconified

Mini mode (button "Mini" or menu Project -> Mini mode):
 - small temperature strip on the screen title bar
 - same colours as the title bar; red with "!" when hot (80 C,
   throttling) or on under-voltage
 - click the temperature: full window back
 - drag it with the mouse: moves left/right on the title bar
 - "x" quits; right mouse button: small menu (Show gauge, Quit)
 - checkbox "Start in mini mode" in the main window: start as
   strip (e.g. from SYS:WBStartup) or as normal window

Details window (button "Details..." or menu Project):
 - board model, revision, RAM, SoC, maker, firmware date
 - ARM, GPU core, V3D and SDRAM clocks: now / min / max
 - allowed core voltage range
 - refreshed only while open

Save report:
 - writes all data to RAM:VCStat-report.txt
 - serial number shortened, MAC address not included

Settings:
 - start mode, strip position, gauge and interval are saved
   at once in ENVARC:VCStat.prefs (delete it to reset)
 - optional tooltypes:
     MINIH=17         strip height in pixels; the icon contains
                      17 (default piAROS title bar), change it if
                      the strip does not match your title bar
     MINIX=75         strip position, percent of screen width
     MINICOLOR=RRGGBB own strip colour (hex)
     MINIBAR=NO       no gauge in the strip

Tested: Raspberry Pi 3B+, Raspberry Pi 4 (8 GB), Raspberry Pi 500+.
Pi 5: should work (same chip as 500+), not tested.

Installation:
 - copy VCStat and VCStat.info anywhere (e.g. SYS:Tools)
 - to start at boot, put them into SYS:WBStartup

Troubleshooting / reporting a problem:
 1. Menu Project -> Save report... creates RAM:VCStat-report.txt
    (safe to post: no MAC, shortened serial)
 2. If VCStat shows no values ("--" or "No valid answer from the
    VideoCore mailbox"), also run in a Shell:
        vcdiag >RAM:vcdiag.txt
    (read-only, changes nothing)
 3. RAM: is cleared at reboot, so copy the files:
        copy RAM:VCStat-report.txt RAM:vcdiag.txt SYS:
 4. Send them with your Pi model and AROS version:
    e-mail below, or post on the forum
 Notes:
  - "n/a" = your firmware does not support that request
  - under-voltage "since boot: YES" = power supply or cable
    problem, not a VCStat problem

History:
 0.6    mini mode: temperature strip on the title bar (drag,
        colours, red warning), "Start in mini mode", settings
        saved in ENVARC:VCStat.prefs
 0.5.1  tested on Pi 500+ (thanks to the tester!): 500+ model
        name; SDRAM clock and core voltage range hidden on
        Pi 5/500 (not meaningful there)
 0.5    Details window (board, firmware, all clocks), Save report,
        menu, About window
 0.4    bug fixes: failed mailbox call could hang the system;
        buffer always below 4 GB; Pi 5/500 mailbox address;
        vcdiag tool added
 0.3    bug fixes
 0.2    universal build using mbox.resource
 0.1    first version, Raspberry Pi 3 only
