Erich,

Thanks for all your work.

You may wish to advertise the vacancy on the USENET comp.lang.forth. A
G account will do the job.

[Amforth] AmForth Project open for adoption

[Erich W. <ew....@na...>]

Dear AmForthers,

I am herewith stepping down from the maintainer role of AmForth. For details,
read on. If anyone is interested to take over, get in touch with me.


In 2020 I received the logins of amforth.sourceforge.net, basically because I
was lucky enough to have met Matthias personally a few times. At that time I
had a lot of ideas on how to proceed. And while I managed to create an
official release, there are a few obstacles in this path.

First and foremost I am facing a health issue. It is subtle, but it
seriously limits, what I can do. I still have to make several difficult
decisions regarding my daily life. I have started to decrease the number of
things on my list by cancelling items. I have to accept the fact, that I'm not
in a position any more to advance the AmForth project in a meaningful way.

Secondly, AmForth has become complex over time. Matthias added support for
three more target platforms (msp430, arm, riscv32). Allthough access to these
is easily achievable, I use only avr. And I use it less these days.

Thirdly, AmForths tools are depending heavily on python code, a language I
consider myself illiterate in. I have written a few small perl scripts around
AmForth to serve my needs. I heavily depend on those and on a Makefile.

Add the fact, that in 2020 I spent countless hours to port my data acquisition
stuff at home from amforth 4.6 to 6.9 and it just did not become stable. To
this day I still have no clue, why the thing hangs itself after some time,
sometimes hours, sometimes several days. In other words: unusable.


Step back: what would I have done, if I didn't know Matthias, and the project
would just have become silent? Simplify. Simplify heavily.

Very recently I have made a fork of AmForth release 5.0. That version is
before support for msp430 was officially added (5.5). That version happens to
compile with avra rather than wine/avrasm2.exe. Along the way I found, that
avra has seen new releases, which add support for my beloved atmega644p and
lots of fixes, which is nice! This removes the dependancy from wine and allows
for smaller systems for development.

So I have picked up my data acquisition project again with the fork mentioned
above. Any Interrupt Service Routines are written in assembly to avoid the
thing that I uncovered in 2017, namely a race condition 1 bit wide and 1
instruction cycle long. I pick missing bits and pieces from later releases. I
would like to add a few features regarding sensors with different needs. A
first experiment has run more than 10^6s (12d) without any failure. So I am
moderately optimistic to continue along this simplified path.


Thanks to all, who have answered the list, contributed code, ideas,
documentation in one form or other. It has been an interesting experience.
And should you still care to listen: if you have one or a few more important
plans, do not delay them, you might be unable to pursue them later.

Happy hacking, and use the Forth!

Cheers
Erich

Re: [Amforth] AmForth 6.9 on Arduino MEGA using ATmega2560- No reponse at console

[George H. <jac...@gm...>]

The big advantage with the Arduino Mega is lots of 8 bit ports available
for parrallel i/o.  The Arduino Uno pretty much forces all i/o to be
serialized one way or another.

64k only (which is heaps) - W and IP are 16-bits only. The upper 64k is
still available, a little bit is used for the flashing code. I use
some of this space for user messages.

The clones work fine. Out of the box you might have to blow the fuses
first - before flashing the memory.

Re: [Amforth] AmForth 6.9 on Arduino MEGA using ATmega2560- No reponse at console

[George H. <jac...@gm...>]

Hello,
I  believe only 50% of the Arduino Mega flash is available to Forth for
dictionary use.

This is simply a hardware barrier that exists. The additional 126kb
theoretically can be put to use in other ways, but I've not seem actually
solutions.

Re: [Amforth] AmForth 6.9 on Arduino MEGA using ATmega2560- No reponse at console

[Tristan W. <ho...@tj...>]

Hi Christian,

Glad it worked.

> How much of 256KB flash is effectively usable with AmForth on the 2560? ?

Good question. I don't know. The file avr8/words/store-i_big.asm may give some
clues. 

> Will this work as well on a Chinese  ATmega2560ProMini (with FTDI USB chip for terminal input) ?

Again, I don't know. However, if the board has an ATmega2560 mcu
running at 16 MHz then there is good chance. I think only by flashing
the board and testing it will you have a better idea. 

> If so, may I share your links with a friend who has an  ATmega2560ProMini?

Yes.

Kind regards,

Tristan

Hi Tristan.

Your r2457AmForth  version is working fine on my Arduino MEGA with ATmega2560, except for a few garbled character after the reset. But that is probably normal. It occurs on the UNO as well.

Some question:

  *   How much of 256KB flash is effectively usable with AmForth on the 2560?
  *   Will this work as well on a Chinese  ATmega2560ProMini (with FTDI USB chip for terminal input) ?
  *   If so, may I share your links with a friend who has an  ATmega2560ProMini?

Thanks a lot for your help.

[Amforth] AmForth 6.9 on Arduino MEGA using ATmega2560- No reponse at console

[Christian H. <hin...@ou...>]

Hi to your support team.

I have AmForth working properly on an Arduino UNO.

I am now trying to use it with an Arduino MEGA using the Atmega2560 but I get no console response after programming the files  atmega256.hex  and atmega256.eep.hex from folder \amforth-6.9\appl\atmega2561 of downloaded file amforth-6.9.zip.

I still consider myself as a beginner hobbyist and  I do not yet have the ability to assemble my one code from source.

  *   Are these Hex file effectively compatible with the Arduino MEGA using the ATmega2560 ?
  *   What are the fuses that I should use with the Arduino MEGA.using the ATmega2560 ?

I am currently using the followings fuses:

Reading fuses...
>>>: avrdude -u -c usbasp -p m2560 -P usb -b 115200 -B 1.0 -U hfuse:r:-:h -U lfuse:r:-:h -U efuse:r:-:h
SUCCESS: Read high fuse
SUCCESS: Read low fuse
SUCCESS: Read extended fuse

My serial port COM7 is transmitting to the Arduino MEGA  because I can see the RX LED flashing. I don not see an response on the TX LED or the console.

  *   Am I using HEX files that are not compatible with the Arduino MEGA using an ATmega2560 MCU ?
  *   If not, what can I do to make these files work with the Arduino MEGA using the ATmega2560.

I would appreciate your help to resolve this problem.

Thanks.

[Amforth] Summary for ATmega644P

[Stephen S. <dee...@gm...>]

I did load the *'amforth-6.9\appl\eval-pollin\p644.*'* hex and eep files to
check things.  It works and I can make new words.  But, when I loaded (via
realterm, all ok):

   - to-name.frt
   - see.frt

see always returns 'not found' on any word I try.
> ' see see

not found ok

> ' reveal see

not found ok

>

------------------------------ In addition -----------------------
For whatever reason the "sanguino" does not work.  See previous for UART
setup, I used what was there in the assembly file.  I did check all of the
hardware and settings you mentioned. The 644 that I am using is the same as
above.  Same baud rate (preamble.inc).  It does not appear to me, on the
surface, that there is a difference between this and the p644 (from a
hardware/setup  perspective), just a USART.  I have been busier than usual,
but will work on things this weekend, dig into the template file and start
from scratch.

Regards & thanks.

concentrating on this part.

The controller never talks to you? Is that "the error"?

given:
- controller atmega644p
- board? sanguino??? I don't think, I have one of those ...

releases/6.9/appl/arduino/sanguino.asm says:
| .include "preamble.inc"
| .equ F_CPU = 16000000
| .include "drivers/usart_0.asm"
| .include "amforth.asm"

- crystal frequency? 16 MHz
- uart? usart_0.asm, which means pins d0,d1


Now. The Arduinos are sold with a bootloader on them and
specific fuse settings. As far as I can tell, you always need to
double check and mostly change the fuses.

on atmega644p I use LFUSE=0xd7 HFUSE=0x99
or (more often)     LFUSE=0xe6 HFUSE=0x99

releases/6.9/appl/arduino/readme.txt says:
Fuses (E,H,L) FD F9 FF (Sanguino)

So there is a difference. I have in the past prodded a few hours
reading the datasheet to understand this. And then I never touch
it again. There are websites to help with this, but I always use
the datasheet.

Then there is the baudrate hiding somewhere ...
releases/6.9/avr8/preamble.inc says:
; 10 per mille (1 per cent) is ok.
.set BAUD = 38400

ok. Now, what do I actually use? I have started with amforth
before the appl/arduino directory existed. So I always base my
projects on appl/template. And thus:

| .../firmware/station-0x7f 33 > grep -v '^;' main.asm | grep -v '^$'
| .include "preamble.inc"
| .set AMFORTH_RO_SEG = NRWW_START_ADDR
| .equ F_CPU = 11059200
| .set BAUD=115200
| .include "drivers/usart_0.asm"
| .set WANT_IGNORECASE = 0
| .set WANT_INTERRUPTS = 1
| .set WANT_INTERRUPT_COUNTERS = 1
| .include "amforth.asm"

Note that I use a baud rate crystal.

Does this help?

Erich

Well, the 644 has *two* serial interfaces, so one thing could
be, that you have included the wrong definition file. I do use
644PA all the time. I have a definition file for 644P somewhere,
but I need to look for it.

Another common error is the clock frequency. There is the what
the crystal has printed on. And then there are a few fuse bits,
which can make life miserable:
- there is a bit to use the internal RC oszillator at 1 MHz
  iirc.
- there is a bit to divide clock by 8 or maybe it was uart
  clock??? But configuring baud rate/8 on your terminal might
  help.

I'll check for the configuration I use over the weekend.

It's probably something minor. And you probably checked all of
the above.

I would not expect the prebuilt uno.* files to work on a 328P_B_

[Amforth] ATmega328PB - hanging

[Stephen S. <dee...@gm...>]

I did see posts/problems with different implementations of AmForth hanging.

Not sure they are related to my issues, but they do seem similar by
description.

*One additional note:*
*The EEPROM has to be reprogrammed for the 328PB to recover, a power cycle
actually does not work!*

I did load the 644 version from the *eval-pollin* directory to my board and
it works fine, so I know it can be built.  Will try the 328 version later
on my Microchip 328PB board.

[Amforth] General AVR (644P and 328Px)

[Stephen S. <dee...@gm...>]

I have been trying to get the 644P  'sanguino' to build and run, but it
never initializes uart0 properly. Leaves out the initialization of the
UBRR.  The baud rate is defined in the INC.  I believe that I have gone
through the instructions as best I can, but they don't exactly (to me)
match the 6.9 layout.  I have been able to build from both the command line
and MicroChip studio.  I have been working with AVR for well over 20 years.

So, then I tried the UNO.hex and UNO.eep.hex on the Microchip ATmega328PB
from the arduino directory.  It appears the PB is not compatible with the
UNO (I don't have another option).  While it does run after any definition
it tends to stop responding/hangs (for a bit).  For example:







*amforth 6.9 ATmega328P Forthduino> 3 4 + .7  ok> : x2 dup + ;  ok> 2 x2 .*



*amforth 6.9 ATmega328P Forthduino> 2 x2 .amforth 6.9 ATmega328P
Forthduino> 3 4 + .*

As you can see I get the banner and a prompt.  Operations like add work
until a definition, such as, x2.  All seems fine after the 'x2' definition,
but any attempt to use it fails.  Using the definition of x2 will cause the
banner to reappear after several seconds. Trying to print from the top of
the stack also causes a new banner.  The only way to recover is a
reset/power cycle.  The EEPROM no longer matches the original UNO.eep.hex
file (not sure if this is normal or not)..

I will continue to work things, I want to eventually augment my engine
control unit with an ATmega64M1 via CAN.  I have an extensive amount of CAN
related software and peripherals that I would like to interface with FORTH.

Any hints or suggestions would be appreciated.

[Amforth] ATmega64M1 and similar

[Stephen S. <dee...@gm...>]

There does not seem to be any UART defined for this family.

There is a LINxxx/UART component that can either be used for a LIN bus or a
UART, but it does not have the usual UDRxx structure.  I was wondering if
anyone had actually ported to the chip, there seems to be nothing in the
mailing list.

I am trying to mimic the UDRxxx implementation, but have not had much
success  so far.

[Amforth] Studio 7 Questions

[CVBruce <cv...@gm...>]

Hi all,

I finally gave up on finding a download of avrasm2.exe and associated files and downloaded Studio 7.

For those of your that have installed/run Studio 7 on non-intel Linux is there a preference between Wine and Box86 environments? Does one work better than the other?

Second question, If I remember the last time I did this, there were instructions on what to copy out of the Studio installed files to set up a command line tool chain for building AmForth that were, shall we say, less than perfect.  Are the current instructions “correct”?  Better yet does someone have a batch/shell script that will do the job for me.

Thanks,

Bruce

I absolutely agree. And the Studio 7 comes with avrasm2. There is a
version update from 2.1.52 as you can find in
appl\atmega2561\atmega256.lst to the current version 2.2.8. But this is
not important.

The target is an atmega2560. The device signature is 0x1e9801, and C
programs run fine.

It was not a question of the build environment (make/Studio) or the OS.

The main difference between the ATmega328P and the ATmega2560 is the  is
that the file appl_8k.inc is included, if the flash size is > 8000. The
asmforth.asm can't be used in that case as it is described in
http://amforth.sourceforge.net/UG/windows.html

Instead of "amforth.asm" the file "asmforth-low.asm" must be included.
This can also be found at appl\atmega2561\atmega256.asm. But this
example is not for Arduino ATMEGA256. It uses a different USART for the
terminal.

Here is my working example:

; First is to include macros and default settings from the amforth
; directory.
	.include "preamble.inc"
; amforth needs two essential parameters
; CPU clock in hertz, 1MHz is factory default
	.equ F_CPU = 16000000
; and the actual USART port.
	.include "drivers/usart_0.asm"
; Include the whole source tree.
	.include "amforth-low.asm"

And here are the avrdude parameter to flash the device
-c usbasp -p m2560 -V -u -U flash:w:my.hex -U eeprom:w:my.eep \
	-U efuse:w:0xFD:m -U hfuse:w:0xDF:m -U lfuse:w:0xFF:m

I am happy that I can now start Forth on my ATMEGA2560 Arduino.

Best regards,
Helge

Re: [Amforth] Building amForth with Microchip Studio 7

[Tristan W. <ho...@tj...>]

Hi Helge,

A mystery, but given that, as far as I know, every (modern) build
eventually uses avrasm2.exe to create the hex files, one that should
be solvable. Given that you have an UNO build working, I can only
think that your atmega2560 build is not finding all the needed files
(or finding some it shouldn't) or that the build target is not
actually an atmega2560. 

I use a Makefile based build (on macos) that is based on the one that
is part of the distribution. I can send you an archive with the
Makefile, list file, etc. for you to check over. I don't have access
to a Windows machine or I would try to replicate what you are doing.

Kind regards,

Tristan

Well, the .lss doesn't show the source lines for the atmega2560. But I see

atmega2560:
dict/nrww.inc(93): Including file 'words/store-i_big.asm'

atmega328p:
dict/nrww.inc(95): Including file 'words/store-i_nrww.asm'

as you expected. Further the core_8k.inc is included for the 256 instead
of the core_4k.inc for 328p.

Should I send the .lss file (121k) or make it somewhere available?


Best regards,

Hi Helge,

Glad you got AmForth to build with an atmega328p.

Can you make avrasm2.exe output a list file, re-build and then check
the list file for lines containing store-i ?

For the atmega2560 I would expect 

                 .include "words/store-i.asm"
                 .include "words/store-i_big.asm"

For the atmega328p I would expect

                 .include "words/store-i.asm"
                 .include "words/store-i_nrww.asm"

Kind regards,

Tristan

This is a good point! With the correct include path I get a working,
self-compiled amForth. Further I removed the -im32def.inc. The file is
included in the amForth sources anyway.

Thank you.

Now I want to take the second step, build for ATmega2560. I use nearly
the same avrsam2 command line, but changed the include path from
     amforth-6.9\avr8\devices\atmega32
to
     amforth-6.9\avr8\devices\atmega2560

avrasm2.exe -fI -o my2560.hex -e my2560.eep -S my2560.tmp -W+ie
-I"amforth-6.9\avr8" -I"amforth-6.9\avr8\devices\atmega2560"
-I"amforth-6.9\appl\arduino" -I"amforth-6.9\common" -d
"Debug\my2560.obj"  "main.asm"  -I "D:\Program Files
(x86)\Atmel\Studio\7.0\toolchain\avr8\avrassembler\Include"

Now I get several errors like:
error: Overlap in .cseg: addr=0x1f000 conflicts with 0x1f000:0x1f396
error: Overlap in .cseg: addr=0x1f001 conflicts with 0x1f000:0x1f396
...
error: Overlap in .cseg: addr=0x1f03e conflicts with 0x1f000:0x1f396

Shouldn't this compile out of the box?
I am also curious about this range 0x1f000:0xf1396.

Best regards,
Helge

Re: [Amforth] Building amForth with Microchip Studio 7

[George H. <jac...@gm...>]

Hi Helen,
I strongly advise you to* avoid *use of Atmel Studio or the Microchip
successor.

Using the standalone Atmel assembler in Windows is a much easier solution
to control. The Microsoft VisualStudio software bogs down and has a very
challenging learning curve with getting good results.

*It sounds as though you successfully compiled binaries in hex files, but
you may very likely hit a snag in AVRDUDE. *

It is very common when installing Forth to deploy the wrong fuse setting
and end up with no serial port response. So you might consider using an
online Atmel Fuse calculator to confirm your fuse settings.

HERE IS A LINK ==> https://www.engbedded.com/fusecalc/

THERE ARE OTHERS IF THIS ONE DOESN'T APPEAL TO YOU.

+++++++++++++++++++++++++
Also, make sure that you understand what the AVRDUDE output is saying.
There are 3 separate parts to a successful download.  The .hex file for the
flash, the .hex file for the eeprom, and the FUSE settings.

If you don't your ATmega2560 binaries are correctly compiled, AmForth does
have precompiled ready to load ATmega328p binaries that you can load to an
ArduinoUNO as a way of learning to understand AVRDUDE and proper FUSE
settings.

I hope this will help.
George Herzog
