Re: [Flashforth-devel] FlashForth

[Mikael N. <mik...@pp...>]

Thanks Mike,

WRT your questions.
1) I have only used the ASM30 and C30 suites.
The MPLAB project files tool paths may not agree with your installation.
Or was it some othet problem with ASM30 ?
2) I never quite figured what the Microchip logic is for defining  the 
processor family macros. I have noticed the same behaviour as you.
3) There could be a config option for selecting the OPERATOR UART.
The Atmega FF has that.
4) It would be possible to use EEPROM emulation or external EEPROM
for those 18F parts which do not have EEPROM. I actually
did a version for FF3.x with EEPROM emulation but it was never quite 
finalized.

If you want, you could ship a container of wine to me, hi, hi.

And finally, please join and post to the mailing list. It spreads the 
information better.

Its been very quiet on the mailing list.
I assume there are no problems, or nobody is using FlashForth.
