During some spare free time I've ported parts of the Arduino AVR
library to Free Pascal. So now it is possible to use things like
'DigitalWrite' and 'Delay'.
BTW, IMHO, porting Arduino wiring code is not the way to go. Their
libraries are written with an ease of use philosophy and they try to
optimize them with the use of a lot of linker and preprocessor trickery,
which are not easy to port.
I would say that it was not that difficult to port. Although I could not
port all the 'trickery' literally.
And it was my intention to follow the 'ease of use philosophy'. That is
exactly what was missing at the Freepascal side of Arduino development.
When you are more experienced, you might not need this, and you are
better of writing to the corresponding addresses, instead of using
'DigitalWrite'. This is for beginners and simple proof-of-concepts. (The
developers of the original Arduino software also state this)
IMHO, if you want to use library or framework I'll recommend to take
a look to Michael Ring's Microcontroller Board Framework MBF (
https://github.com/michael-ring/mbf ). I think that has support for AVR.
Could be a good tip, I didn't know about it's existence.
One question off topic, can anyone register and use the gitlab scm
server ( gitlab.freepascal.org ) ? Is it open for Free Pascal / Lazarus
projects ?
Michael can tell you more. But as I understood it it is more a
proof-of-concept at the moment. A playground to get more familiar
hosting git, in preparation of the switch from Subversion to Git for the
Free Pascal sources.
But at this moment nothing has been decided. Especially if we are gonna
host fpc on Gitlab itself or host it on our on.

Joost.
