Dear,

Reading the book

https://owa.groupware.kuleuven.be/owa/redir.aspx?C=RMe8cNdhykm94I0qM4qYnaswobpeOM8Ih4neGmXrOgRpz8FNa5MO2QgTWy0YwOx2N8G644q2tio.&URL=http%3a%2f%2fbooks.google.be%2fbooks%3fid%3djZaFzm5drYwC%26pg%3dPA247%26lpg%3dPA247%26dq%3dtransterpreter%2bffi%2bblocking%26source%3dbl%26ots%3dRVsVsYWYZA%26sig%3d1Znmv514JsD1AeYKkmsXiLnrxqc%26hl%3dnl%26sa%3dX%26ei%3d-p8FUPHzIMrRhAee_pzFBw%26ved%3d0CGIQ6AEwAw%23v%3donepage%26q%3dtransterpreter%2520ffi%2520blocking%26f%3dfalse

pages 247 an further it anounses SWI and FFI Blocking, Non-Blocking and Non-Blocking interruptable C function calls.

Are those tree already implemented in the arduino transterpreter ?

We would like to use (non-)blocking function calls to set up inter processor communication emulating the good old transputer links.

The link could be a serial interface with RX/TX communication buffer or a memory mapped DMA handled RX/TX communication buffer.

Any advices about how to incorporate such functionality is welcome.

Greatings,

Patrick
