Re: [Amforth] Newbie with a mega2560
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 out as I pour over this listing, I'm sure. Getting ready for our Field Day weekend, which starts tomorrow at 11:00 local time and runs through Sunday 11:00. This will be the last year we work under COVID rules, meaning I work from home and log via the internet. We normally head out for a camping weekend on some Forest Service land that we obtain a permit to use. It's located at around 6500 feet and gives us nice coverage. Have you tried experimenting with the MSP430? As I remember, I picked up a few of these boards back when they first were introduced. I bought a few of them (called Launchpads) and played with one for a while, but wanted to more than it was capable of at the time. So many parts ... so little time ... !! :) Kind regards, Michael k6MLE On 6/17/2021 2:38 AM, Erich Wälde wrote: Hello Michael, Michael Picco writes: Hello!

Re: [Amforth] Newbie with a mega2560
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 as the directive #include). The documentation is in the python3 source.

It's the same high fuse setting as I suggested but with the jtag interface activated. I don't use that so I turned it off. Where did you get the 0xDC setting for that fuse from? It really does seem to be incorrect for a chip with 4k bootloader. Having just looked back into the atmega2561 appl directory I just realized there isn't a makefile (or I suppose, a bat file for windows) with the amforth defauts in it. I was just getting ready to burn this into old 3D printer mega when I saw Tristan had already done just that. Good luck with the project!

Re: [Amforth] Newbie with a mega2560
Hello, Several years ago (Nov 2012), I tried to get amforth running on an Arduine2560. After a LOT of pain I succeded. I wrote the following to the board, and it is probably somewhere in the archives. Anyway……I do not know if the issues that you are experiencing are the same, but it sure sounds familiar….. here goes: I've been trying to get amforth running on an ARDUINO MEGA 2560. I've been using Atmel Studio 6, and a avr dragon board to do the programming, AND i have been using the atmel provided device programming tool (not avrdude). I have managed to make it all work, though. Its a pretty ugly hack. I have been studying amforth, and I *think* that I sorta understand how it works. Here in a nut shell is what I ended up doing. If you compile the code and try to burn it into the arduino board, it simply will not work. The Atmel software loads the lower code where it belongs, but then it loads the high code wayy up at $3E000, which is exactly what the code tells it to do. I am not conversant enough with the amforth code to know how to make it work up there, and try as I might, I could not find any reference to anybody who had succeeded in doing so. What I ended up doing was this.. I manually orged the high code to $3800. This will work until you want to create a new word, or write to flash, at which point the code locks up because it cannot write to that section of flash from there. In the core word !i-nrww I put a jump to DO_STOREI_atmega. I put a label on the pop yh statement that follows that. I cut the entire DO_STOREI_atmega section out. at the end of the last piece of high section code, (i think it was words), I put an .org $1f000 and pasted the DO_STOREI_atmega code there. After the rcall dospm, I put a jmp back to the pop yh statement that follows that. Although that, in fact, would have worked, I didn't realize it because the process of burning the code into the arduino involved burning the flash, then the eeprom. Unfortunately immediately after the flash is burned, the arduino resets, cannot find its brains in the eeprom, and encounters the relocated !i-nrww code which promptly erases a goodly part of the first page of flash. The solution I ended up with was to place a simple continuously looping assembly led blinky routine immediately after the .org $1f000, with the !i-nrww code immediately after that. This works. As far as I can see, it is a normal amforth installation. I can create new words, and so far things seem to work. > On May 23, 2021, at 7:02 PM, Michael Picco wrote: > > Thank you for that. > Reading up on them yields: > not found ... the position in the input line indicates the system choked on > the word 'words'. > > words is part of the flashed system. > > This indicates (to me) that something got corrupted.

Re: [Amforth] Newbie with a mega2560
Hello. If your High fuse is set to 0xDC that is probably your problem. From what I see that gives you a 1k boot section and Amforth is probably trying to blast past that. I have some strange fails when I first flashed my 1284p chips. Checking with a fuse calculator it looks like that chip should be D9 for a 4k boot section. Here is a link to the calculator I used. http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega2560=E0=D9=FC=FF Hope that is a bit helpful, Mark On Mon, May 24, 2021 at 11:47 AM tristan wrote: > Hi Michael, > > AmForth uses a dictionary to store the words it knows about.

Re: [Amforth] Newbie with a mega2560
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 marker.frt is the definition for the word marker. This word will create a word that will manipulate the dictionary. See this link below http://amforth.sourceforge.net/TG/recipes/Forget.html Your AmForth system is indeed corrupted (and will need to be re-flashed). Why it has become corrupted needs some more investigation. Perhaps there is a word that marker relies on that is missing from your hex build, perhaps you made a typo when typing in the definition, perhaps you have found a bug[a]. I would 1. Re-flash the board 2. Connect over serial, check that word lists the dictionary, define a trivial word e.g. : xx 1 + ; and check that it works and can be listed in the dictionary. 3. Use amforth-shell.py to load avr8/lib/forth2012/core-ext/marker.frt 4. Repeat 2. 5.

Hi Michael, I do not see the word 'marker' defined. Should it have been part of the basic system, or do I need to pull it from somewhere?

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.

I use minicom and amforth-shell.py You will need to identify the name of the serial device created by the USB to SERIAL chip on your board/setup to use any serial program. Once connected you have the AmForth interpreter prompt and can interact, compile new words, and generally use the system. However, AmForth is modular and not all functionality is contained in the flashed hex files. For I2C and SPI new words need to be defined. These definitions are already available within the archive, but need to be loaded onto a "new" AmForth system. I find amforth-shell.py very helpful for automating this process. The cookbook is a great place to see examples of how things can be done http://amforth.sourceforge.net/TG/Cookbook.html And for I2C, below is very helpful http://amforth.sourceforge.net/TG/recipes/I2C-Generic.html Let us know how you get on.

Do I have these > correct? Fuses are a bit tricky. You can sort of brick your device. It will not talk to you any more, and ways out are with varying tricks ... So be careful. I do not have a 2560. If I had to use one, I would hunt down the data sheet and read the section about the fuses. And this is plenty confusing stuff. Try to translate the above settings into words. Bit by bit. There is also a "fuse calculator" somewhere online ... http://eleccelerator.com/fusecalc/ There is even an Android App for this LOL! https://play.google.com/store/apps/details?id=me.chayan.avrfusecalculator=en_US=US Again: Do not brick your only one device! If you can possibly help it :-) I have done this. So you don't have to, right? > Once I get this figured out, I'd like to submit a write-up for newbies and > perhaps draw more users into AmForth. There is some document about your setup ... vom Karl maybe ... http://amforth.sourceforge.net/UG/amforth_user.html http://amforth.sourceforge.net/UG/windows.html I have no idea how useful this is today.

Re: [Amforth] Newbie with a mega2560
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 would be very welcome! As pointed out you need a programmer (such as usbtiny, usbasp, avrisp2 etc.) and a program to talk to the programmer (such as avrdude). Both atmega2560.hex and atmega2560.eep.hex need to be written to the mega2560's flash/eeprom. Below are the command lines I use with avrdude avrdude -p m2560 -c usbtiny -U flash:w:atmega2560.hex:i avrdude -p m2560 -c usbtiny -U eeprom:w:atmega2560.eep.hex:i Flashing these file will overwrite any existing bootloader. It is worth considering whether you are able to reverse this should you wish to, before flashing the above files. If your mega2560 is an Arduino style board, and the default fuses unchanged, then IIRC there is no need to reprogram the fuses. Once the files have been flashed, you should be able to connect to the mega2560 over serial using 38400 8N1. I use minicom and amforth-shell.py You will need to identify the name of the serial device created by the USB to SERIAL chip on your board/setup to use any serial program.
