Hello Erich,
I've dusted off an MSP430 board I have here and might have to load it
with noforth just to get an idea of what his code is doing with the BME280.
He uses some sort of defining word called 'value', that I need to look
up with the MSP430.
There are a lot of others that will jump

Hello!
I finally have figured out how to efficiently interact with Amforth on
my mega2560 and have installed much of the I2C stuff on it.
Question:
Has anyone worked out how to talk to the BME280 sensor using Amforth?
Wading through the spec sheet tells me it's going to be a challenge. It
Hi Michael,
Glad it is working.
I use amforth-shell.py which is in the tools directory. It needs
python3 and pySerial to be installed to work.
A basic command line looks like this
amforth-shell.py --port DEVICE --speed 38400 FILE_TO_UPLOAD
but there are many other options and commands (such

Hi Michael,
I hope you got AmForth to build successfully under windows for the
atmega2560, but if not, I have built it for my Arduino MEGA using the
most recent source (r2457).

I have uploaded the resulting hex files to

Hello Martin,
Thank you for responding!
In my work directory, which is aptly named 'amforth-6.9', I don't see a
copy of the template.asm file with "amforth-low.asm" mentioned. The
amforth-low.asm file is referenced in the avr8 subdirectory. Is there
something I am missing?
Kind regards,
The crucial file to include for an ATmega is the confusingly named:
"amforth-low.asm" which needs to be un-commented in template.asm.
All the code is then in low flash memory apart from the flash burning
routine which should be found at NRWW_START_ADDR (0x01f000).
Often, with a new device, you

Hi Michael,
AmForth uses a dictionary to store the words it knows about. When
AmForth recognises it has received a word over the serial line it tries
to lookup that word in its dictionary. If it finds the word, it executes
that word. If it does not, then it reports an error.
In the file
Thank you for that.
Reading up on them yields:

on the word 'words'.

This indicates (to me) that something got corrupted. I can only wonder
if memory got overwritten somehow. Is
There are AmForth error codes. Read up on them.

Hello!
I seem to have stumbled across an issue.
First code I wrote was to blink the LED onboard. This worked just fine.
Then I went to add 'marker'. Entered it line-by-line ... got the 'Ok'
after each line. After adding the last line (semicolon), the board
froze up. Did a warm boot and
Hi Michael,
Apologies. My memory is failing me.
The LED is on D13 for both UNO and MEGA, but D13 is mapped to PB5 (PORTB
bit 5) on the UNO and PB7 (PORTB bit 7) on the MEGA.
Best wishes,

Hi Michael,
I do not see the word 'marker' defined. Should it have been part of

It is not part of the basic system, it is defined in this file.

Using marker is efficient/good practice/etc. but
Thanks, knowing what it takes for a successful installation is a valuable
contribution to AmForth users.
The ATmega2560 is very appealing as the added i/o ports make it much more
versatile than the ATmega328p.

Hello Michael,
Getting AmForth up and running from archive hex files on a mega2560 is
reasonably straightforward, however, I don't use Microchip Studio
version 7 or win10 so I can't help with this tool set. I hope you able
to translate the macos/linux to your tools - and if so a write-up
Be careful, the fuse settings particularly the boot size is different
for flash forth vs amforth.
