Re: [Amforth] Newbie getting started with AVR128DA48
Both 328eForth and FlashForth wpuld be easier starting points for a newbie. If one must use AmForth, studying the directory structure and content is key to finding out how to compile to a specific target.

Re: [Amforth] Newbie getting started with AVR128DA48
Perhaps the Arduino controlled by Eforth would be a good help. It has the full assembly code explained for eforth might be a good jumping off point its available at http://www.forth.org/OffeteStore/OffeteStore.html. A good read no matter what.

Re: [Amforth] Newbie getting started with AVR128DA48
Hello Stephen, I wanted to do something similar with the ATmega4809 on a Curiosity Nano last year but ran out of time/skill. https://sourceforge.net/p/amforth/mailman/search/?q=4809 > There appear to be a number of changes at the C macro and register level > from the previous mega generation.

That was what I found also, and would agree that it may require a fair bit of rework - both in terms of the AmForth code, but also the tool chain more generally. All that being said, to have AmForth able to run on this newer generation of mcu would be fantastic.

Well, well. This is one of the secrets that I have not yet uncovered from the files I have. You might not know that the author of AmForth has left this planet earlier this year. So we have to make due with some code archeology :) AVR128DA48. What a beast. I skimmed the datasheet only briefly https://www.microchip.com/wwwproducts/en/AVR128DA48 If you want to work your way to support this chip, I suggest to make a twofold approach: 1. Have a controller, which is supported by AmForth already, like the venerable atmega328p. Use this to set up the whole tool chain and verify, that you can build and upload it, and that the result is actually working. Unless, of course, you have done this already. 2. Then try to fill in pieces for the new controller. Start with the files of a supported controller with the same size flash/ram /eeprom. You have to make sure, that the new controller uses the exakt same set of assembly instructions --- it probably does not, because I read the word "hardware multiplier" > The AVR128DA48 microcontroller is part of the AVR DA family > featuring the AVR processor with hardware multiplier - running > at up to 24 MHz and with 128 KB Flash, 16 KB SRAM and 512 > bytes of EEPROM in 48-pin packages.

[Amforth] Newbie getting started with AVR128DA48
Hi all, would like to try running amforth on one of the new AVR processors, the AVR128DA48 to be exact. A Curiosity Nano board turned up this week and I'm keen to give it a try. Am a total newb with regards to amforth and forth in general but have plenty of AVR programming experience, both in C and assembler. Have looked through the User and Technical Guides but not found an answer to my question: How do you define a new AVR8 chip within amforth? I have looked through the files under /avr8/devices/atmega* e.g. device.asm, device.inc etc. They all claim to be "generated automatically". I have not been able to find where the automatic generation is performed. Is anyone able to point me in the right direction please?
