stampbc - STAMP Basic Compiler
------------------------------
tokenizer.so provided by Parallax Inc., Rocklin, CA USA (www.parallax.com).
stampbc developped and provided by Adrian Schneider, Basel, Switzerland
(adrian-schneider4@bluewin.ch)
version 2.1
-----------
BUGFIX:
fixed a object buffer size bug which caused a segmentation fault if an
object file was bigger than 2048 byte (object files can be 2304 bytes).
EXPERIMENTAL:
Added preliminary support for the new BS2px module. The BS2px programs at
19200bps and debugs at 38400bps instead of 9600bps as the other modules do!.
Programs are tokenized for the BS2pe - a warning is issued to report this
fact (it might also be the cause of the different programming/debugging
speeds, as the BS2pe has different timing constants).
Yoy have to use the option -iBS2px explicitly when compiling for the BS2px.
A $STAMP BS2PX directive in the code will issue an error from the tokenizer.
The -i option however overrides this directive.
FEATURE:
overhauled showtty tool. Some new commands have been added:
help display help for the stty command (using 'less', type q to return to
the showtty screen)
bs setup comm port options for stamp communication with a BS2/e/sx/p/pe
bspx as 'bs' but set properties for the BS2px
d set comm port settings for debugging (icrnl)
p set comm port settings for programming (-icrnl)
debug set comm port settings for debugging and open an xterm with limited
(output only) debug capability.
You need to kill that window and use the 'p' command before you can
download to the stamp again since it blocks the comm port.
version 2.0.1
-------------
fixed a few incompatibilities with other compilers in SBTokenizer.cc
version 2.0
-----------
added the new tokenizer 1.23 which supports PBasic 2.5. The -m and -M
options print the language version detected by the tokenizer.
added some byte and word size testing to defs.h so it would complain
about just in case...
version 1.2.5
-------------
reworked the reset/break condition sequence which was not quite after
the specifiection in "BASIC Stamp Programming Protocol".
version 1.2.4
-------------
tweaked the reset pulse timing - later 1.2.3 versions already contained this
tweak.
fixed a bug which printed the whole source if the tokenizer reported an
error length of 0.
added option -M and modified the behaveiour of option -m. -m now just
reports RAM and percentage memory usage, which is the information that is
usually needed. -M reports EEPROM layout and contents beside memory usage
(as -m did before version 1.2.4).
the percentage memory usage bar is now placed at the end of the memory info
section.
Randy Hootman provided an improved version of the showtty script which copes
better with non-xterm environments. You now can enter 'quit' to terminate
showtty. Instead of '-g' you can also just type 'g' which does the same
(stty -F/dev/... -g).
Some color added to the EEPROM content, layout and RAM usage listings.
version 1.2.3
-------------
this version just fixes a bug with the reset pulse. DTR is cleared, then
set and cleared again. In previous releases DTR was left set which caused
the stamp to be hold in reset state if you connect DTR directly to your
stamp's ATN pin. If you connected the DTR to ATN via series and parallel
capacitors (recommended for improved noise resistance) the level of DTR
did not matter. However, it now works in both cases.
version 1.2.2
-------------
no major new features have been added.
minor tidy up - there were instances of string::data() which were replaced by
c_str(). Replaced deprecated c headers by c++ standard headers (thanks to
Randy Hootman).
now using namespace std - newer environments require explicitly using namespace
std - mine did not - to compile corretcly (thanks to Walti Senn).
minor cosmetic changes to the memory map (RAM register) output.
SBCompiler::printOffendingLine - there was an implementation restriction which
caused a misaligned error locator if the source containd tabs instead of
just blanks. This has been fixed.
added a percentage bar to viusalize the memory occupancy beyond a purely
numerical display.
stampbc
-------
stampbc (stamp basic compiler) is a pbasic compiler utility based on the
tokenizer library provided bi PARALLAX Inc. It allows to compile pbasic
programs, download object code any basic stamp of type BS2, BS2e, BS2sx
BS2p and BS2pe (Honestly, I have not tested the BS2pe as I don't have one).
To use stampbc you have to compile and install it first. For details see
below.
examples
--------
Use stampbc without any options to display a usage summary:
stampbc
stampbc [OPTIONS] [FILENAME]
-c compile single file only
-C compile project only
-d download only
-h help
-i type identify specified stamp type
-j let program identify the stamp
-m output memory usage
-M output memory map and usage
-n syntax check only
-o file with -c use object file name
-p port use specified port for download
-s slot download to specified slot
-v verbose
-V print stampbc and tokenizer version
To display the current version of stampbc and the version of the tokenizer
library incorporated use:
stampbc -V
stampbc v2.0, compiler using PARALLAX tokenizer library 1.23
BTW: You can just replace the tokenizer.so file to apply a newer version as
long as it remains compatible with the previous one - this was not the
case when changing from v1.16 to v1.23.
To test the communication between the computer and the stamp, try:
stampbc -j
This runs an identification procedure. If successful the result should look
something like this (for a BS2e type stamp):
trying to identify the stamp
-- stamp is a BS2e, firmware v1.0
If the stamp can not be identified, is not connected, not powered or if the
serial port settings are incorrect it may look like this:
trying to identify the stamp
** no stamp or unable to identify
A sample BS2 program is provided for testing - it is the same as in the
tokenizer documentation by PARALLAX.
'{$STAMP BS2}
Counter VAR BYTE 'Counter for LED blinks
FOR Counter = 1 to 20 'Loop 20 times
PULSOUT 0,50000 'Blink LED on and off for 1/10 second
PAUSE 250 'Pause 1/4 second
NEXT
STOP
To compile it (without downloading the object code to a stamp) use:
stampbc -c test.bs2
This should produce a new file 'test.o' which can be examined using hexdump:
hexdump test.o
0000000 00fe 0000 0000 0000 0000 1418 8c20 d80e
0000010 7cc8 0eff 4a60 e8ae 499f 50c1 6fc3 d18d
0000020 0703 60c0
0000024
To download 'test.o' to a BS2 stamp use:
stampbc -d test.o
You can also compile and download with just a single command:
stampbc test.bs2
stampbc options
---------------
-c compile single file only
Just compile the source file [FILENAME] specified and produce a .o-file.
Multiple source projects are ignored.
-C compile project only
Virtually the same as -c. However, multiple source (the one given plus up to 7)
projects are also compiled and a .o-file is produced for each.
-d download only
Download the .o-file [FILENAME] to the stamp only. You have to specify the
stamp type using -i and also the slot number using -s for multi bank stamps.
-h help
Display this command summary.
-i type identify specified stamp type
Specify the stamp type. Valid stamp types are BS2, BS2e, BS2sx, BS2p, BS2pe.
BS2 is the default if -i is not used.
This option overrides the {$STAMP} directive from the source.
-j let program identify the stamp
Start a stamp identification procedure. The type and firmware version number
are displayed if the stamp could be identified.
-m output memory usage
Display variable RAM and memory usage after compile. This option is ignored if
compilation is inhibited by an other option (e.g. -d).
-M output memory map and usage
Display a detailed memory map and memory usage info after compile. This option
is ignored if compilation is inhibited by an other option (e.g. -d).
-n syntax check only
Compile the source but do not produce a .o-file. Use for syntax checks or for
just creating a memory map.
-o file with -c use object file name
Use an alternate name for the .o-file. The default for a source file
mysource.bs2 is mysource.o .
-p port use specified port for download
Use an alternate serial port for downloading and identifying. Default is
/dev/ttyS0. The {$PORT} directive from the source overrides the default.
This option overrides the default and the {$PORT} directive as well.
-s slot download to specified slot
Use the specified slot number to download the .o-file to a multi bank stamp.
This option is only useful and needed together with the -d option.
-v verbose
Display some additional information during processing. May be helpful during
debugging or trouble shooting.
-V print stampbc and tokenizer version
Print the version number of stampbc and the tokenizer.so shared library.
installation
------------
You have to unpack the tar-ball, compile and install stampbc. A simple Makefile
is provided therefore.
Create a new directory, cd to this directory an copy the tar-ball there.
as a normal user
tar -zxf stampbc.tar.gz
make clean
make
as superuser
make install
You can also try stampbc from the current directory, but you have to provide
the location for the tokenizer.so library so the shared library loader can
find it:
LD_LIBRARY_PATH=./ ./stampbc
The install target does much the same thing (see Makefile for details). It
copies the executable under a modiefied name '__stampbc' and creates a short
script named 'stampbc' which calls '__stampbc'.
By default the executable is installed to /usr/local/bin and the tokenizer
library to /usr/local/lib.
showtty
-------
showtty is a bash script which uses the 'stty' command in different ways to
show the serial port settings in a readable format and which allows the user to
change settings quickly with just a few keystrokes.
BTW: I heavyly used this script to fiddle around with the serial port settings
when I implemented the download procedure for stampbc. It was very handy, so
I decided to include it here.
You can copy showtty to /usr/local/bin to make it generally available. If
this is the case call showtty with no parameter to show the settings for
/dev/ttyS0 - the default.
showtty
or you can specify which device to display, e.g.
showtty /dev/ttyS1
The showtty utility uses a reverse video xterm to make better use of colors.
On the top in yellow the device name is shown, e.g. /dev/ttyS0.
A selection of the most important parameters are displayed in cyan between the
white lines.
In the lower section, all parameters are shown in detail in green color.
If you don't want to use an xterm start showtty with option noterm as second
parameter (modify the script to change the default behaveiour).
showtty /dev/ttyS0 noterm
To change settings just enter them at the >> prompt, as you would when using
the stty command directly. The new settings will immediately take effect.
Enter -g (or just g) at the >> prompt to get a to print all the current
settings in a stty-readable format (displayed in red color). Just copy andpaste
the string from the terminal window.
Enter quit to terminate the script.
comm settings
-------------
To communicate with the basic stamp, the serial interface settings have to
be setup correctly. Not every setting is really critical. A setup that should
work is listed below (as reported by showtty).
Depending on your system the defaults may vary. To achieve the setting below
I had to enter the following commands at the >> prompt:
9600 raw -echo -hupcl
'-echo' is important since the basic stamp has loopback circuitry on its main
serial port (pin 16 from stamp basic, physically pins 1 SOUT and 2 SIN).
'raw' means that the byte stream is transmitted unchanged as it is provided
by the program.
'-hupcl' avoids certain unintended stamp resets upon opening the serial line.
