Be careful, the fuse settings particularly the boot size is different
for flash forth vs amforth.

Hello,
I have not used Amforth
But the installation mechanisms are the same as for FlashForth:

once FORTH is installed, you must write the programs in FORTH language and
have them compile by FORTH on the ARDUINO card.
FORTH is an interpreter and a compiler. We communicate with FORTH via
terminal software:

Unless I'm mistaken, you need an MKII programmer, because you can only
inject a .HEX file through this device. This operation overwrites the
original bootloader.

Hello,
I am attempting to use the mega2560 as a nicely featured development
platform for AmForth-6.9. The machine I'm using is a Win10 box, with
Microchip Studio version 7 installed.
In the zip file, under appl/atmega2561, I notice atmega256.eep.hex and
atmega256.hex. The eep.hex file doesn't seem to get recognized by
Studio 7. Do I need to rename it to just a ".eep" file?
Can I start building the platform by flashing these files into the
board? If so, what is the process to add functionality (I2C, SPI,
etc.)? As a total newbie!
If it's necessary to recompile and create new hex files, the process is
unclear. Is it spelled out somewhere such that a beginner can follow
some basic steps to make the proper file(s)?
It is my understanding that both flash and EEPROM need to be written,
along with the fuses, [E:0xFF, H: 0xDC, L:0xFF]. Do I have these correct?
Once I get this figured out, I'd like to submit a write-up for newbies
and perhaps draw more users into AmForth. How might I get this posted,
when completed?
Thank you in advance!
Kind regards,
Michael
