Rebuilding your project: yes, it might look intimidating the first time. However, think about the gains: - you can chose another board with a different controller - you can change the clock crystal to another frequency, e.g. I strongly prefer baud rate crystals, e.g. 11059200 Hz. - you can change the baud rate of the serial interface (within limits). - you can extend your AmForth system with a large number or words to fit your project. - you are not locked to use somehow prebuild .hex files The sky is the limit! So: Don't give up too soon, please! This might help if you are linux based: http://amforth.sourceforge.net/UG/linux.html A very long time ago I wrote this: http://amforth.sourceforge.net/pr/Fosdem2011-proceedings-amforth.pdf If you are Windows based, have a look at=20 http://amforth.sourceforge.net/UG/windows.html Cheers, Erich > > Is this also a assembler word? > > Kindly regards, > > Jan > > > > >> Op 7 jun. 2019, om 19:50 heeft Erich Wälde <ew.fo...@nassur.net> het >> volgende geschreven: >> >> Hello Jan, >> >> >> Jan Kromhout writes: >> >>> Hi Tristan, >>> >>> What to load in the right sequence to fellow the examples in >>> http://amforth.sourceforge.net/TG/recipes/SPI.html ? >>> If I have the right sequence of loading the screens I will start as you >>> mentiod. >>> >>> Kind regards, >>> >>> Jan >>> >>> >>> >>> Op 7 jun. 2019, om 19:25 heeft Tristan Williams >>> <h...@tjnw.co.uk<mailto:h...@tjnw.co.uk>> het volgende geschreven: >>> >>> Hi Jan, >>> >>> No don’t have.
