--- calib --------------------------------------------------------------------

Tcl/Tk program used to help calibrate the pressure sensors.  Requires Tcl/Tk
version 8.4.  calib.tcl can take input from randpres.tcl or ss-hw.

--- randpres.c ---------------------------------------------------------------

Test program to generate random pressure/door sensor output.  Use child_init()
to connect the output of this program to ss-hw.  randpres takes an optional
delay parameter to specify the interval between updates.

--- swapcase.c ---------------------------------------------------------------

Silly test program virtually equivalent to "tr a-zA-Z A-Za-z".  This was just
to aid in the development of evlist/child.c.  Use with hex if you prefer
capitalized hexadecimal digits. :^)

--- hex.c --------------------------------------------------------------------

Test program to generate hexadecimal output given a binary stream of data.  Can
be used on the command line as part of a pipe or with child_init().  Useful for
monitoring the RFID protocol output of ss-hw.

--- crc-16.c -----------------------------------------------------------------

Utility program to calculate the CRC-16 checksums used by the RFID tag reader.
Compile with "gcc -o crc-16 crc-16.c".  To use, start the program and type in
packets, one per line, omitting the final two checksum bytes.  For each packet
(line) it will print the two-byte checksum.  Each byte is represented as two
hexadecimal digits.  Non-hex digits are ignored.

--- vec_test.c ---------------------------------------------------------------

Test program for Paul Jarc's vectors and my VEC_BSRCH* macros.  Compile with
"gcc -o vec_test vec_test.c ../prjlibs/*.c -I../prjlibs".  Doesn't do anything
useful... just read the source code.

--- packet.1 -----------------------------------------------------------------

RFID response packet to the 0x01 Inventory command indicating the presense of
one tag with uid 15a1dea7deadbeef.

--- packet.2 -----------------------------------------------------------------

RFID reponse packet to the 0x23 Read Multi Blocks command indicating that the
queried tag has type 0000002.

--- packet.3 -----------------------------------------------------------------

RFID response packet to the 0x01 Inventory command indicating that zero
transponders are present in the RF field.

--- IDEAS --------------------------------------------------------------------

Some ancient code that happens to list some ideas for the future...
