BITSYLOAD(1) BITSYLOAD(1)
NAME
bitsyload, light, pencal, keyboard, params, prompter -
bitsy-specific utilities
SYNOPSIS
bitsy/bitsyload k|r [ file ]
bitsy/light [ intensity ]
bitsy/params [ -f ]
bitsy/pencal
bitsy/keyboard [ -n ]
bitsy/prompter [ -n ] file
DESCRIPTION
Bitsyload erases a section of flash memory on the Bitsy
(iPAQ 3650 or 3830) and copies new information into it,
using the format required by the Compaq boot loader. The
required first argument is the destination, either k for
/dev/flash/kernel or r for /dev/flash/ramdisk. The optional
second argument is the name of the file to load. The
default kernel file is /sys/src/9/bitsy/9bitsy and the
default ramdisk file is /sys/src/9/bitsy/ramdisk.
Light sets the intensity of the display backlight. The val-
ues for intensity are:
on set intensity to maximum, the default
off turn off backlight
n sets the intensity to n, where n is a value between 0
and 128. Intensity 0 doesn't turn off the backlight,
it just sets it to the dimmest value.
Pencal calibrates the display with the touch screen on a
Bitsy. It loops prompting the user with crosses whose cen-
ter that the user must touch with the stylus. After a con-
sistent set of touches, it writes the calibration both to
the kernel and to standard out. It is normally called by
the bitsy's /bin/cpurc.
Params copies the contents of the file /dev/tmpparams, into
the flash partition, /dev/flash/params, or if the -f flag it
set copies in the opposite direction.
Keyboard creates a virtual on-screen keyboard and, unless

the -n option is specified, a scribble area. A user inputs
characters by tapping the keys or by drawing characters in
the scribble area (see scribble(2)). It is usually run as
the keyboard command for rio(1) using rio's -k option.
Prompter is a small editor used to configure parameters when
a Bitsy boots. It displays the file and starts up a key-
board and scribble pad for input. Clicking with the stylus
in the text selects where input characters will go. Press-
ing Button 5 (top left side of the Bitsy) or typing the Esc
key on the keyboard causes prompter to write back the
updated file and exit; Del causes prompter to exit without
writing the file. The -n flag suppresses the scribble area.
EXAMPLE
Prompter, params, and calibrate are used in only one place,
the Bitsy's /rc/bin/cpurc:
# set variables
ramfs
bitsy/params -f
if(! grep -s '^calibrate=' /tmp/tmpparams)
bitsy/pencal >>/tmp/tmpparams
if not {
eval `{grep '^calibrate=' /tmp/tmpparams}
echo calibrate $calibrate > '#m/mousectl'
}
bitsy/prompter /tmp/tmpparams
bitsy/params
