Ja ok, I did mean de Wachter in fact. But yes you also do system calls in olr. J. Sent from my ASUS MeMO Pad Peter Matthias <PeterMatthias@web.de> wrote:
Hi Jan,
I think you got confused with all these Peters here ;-) Jan was talking about Peter de Wachter. And there is also Peter Easthope here. Unfortunately Peter Muller left.
I am not in the details, but I am sure, GPIO can be accessed both, via memory mapped devices and read/write operations, also within Oberon Linux Revival on RPi.
If doing some hybrid (ARM/FPGA) staff I would recommend using existing hardware like MiST board. ( http://harbaum.org/till/mist/index.shtml )

On a scale from 5 .. 0 I would say 4.5 since I dont have a Pi Zero. But in general more rattling of kettles and lighting of fireworks on the Oberon front is Good (tm)
Peter has some way of doing linux system calls. I am sure GPIO could be used that way?
I just need a Round Tuit at the moment for a few things, so don't rely on me. But I _will_ clap for you.
cheers,

With the release of the $5 Raspberry Pi Zero, I started thinking about the viability of a hybrid RISC platform. I've been thinking for a while about how I might simulate networking via a TUN/TAP implementation in Peter's fantastic emulator, but I'm also now wondering if it might be possible to expose the Pi's GPIO to the emulator as well, and end up with something that bridges the FPGA work and the emulator in a way that would be interesting and healthy for both.
Interesting or pointless?
