#39327 — Experimental Mecrisp-Stellaris for Android

Dear Forthers,

I finished an experimental port of Mecrisp-Stellaris to ARM-Android, currently running on a p3310 tablet with Cyanogenmod, and it should be possible to re-assemble it for Linux on any ARMv7. I would love to do a testing run before I include this into the mainstream release package - who is interested may drop me a line, my E-Mail here is valid !

Best wishes from Germany,
Matthias

I wonder: Is nobody on clf using ARM machines like Raspberry 3.14159 or Beaglebone with some sort of Linux ?

I am.  Why?  I run gforth on it for simple stuff.  Mostly it is a remote 
interface so I can program the Stellaris MCU board remotely from my PC. 
  The rPi runs Raspbian which I am told is pretty much Debian.

I have been asked on the German Forth association meeting for a port of Mecrisp-Stellaris to big ARMs for realtime data aquisition and signal generation. But to reach the goal, quite a lot of testing and interface design is necessary. I think a good milestone is to conquer large ARMs already running an OS which I need testing for.

I'm happy to run tests.  I wouldn't be able to do compiles or such 
unless I am given fairly detailed instructions.  I am very green with 
Linux.

BTW, there are parts of the rPi CPU that are not documented.  The 
graphic core is proprietary.

I'm curious about the task though.  What sort of signal generation are 
you talking about?  What would be the platform for data acquisition? 
The CPUs themselves don't typically have inputs for that although I 
believe the BBB CPU has one channel of ADC.  I believe the intended 
purpose is for voltage measurements.  I suppose the actual signal 
acquisition would be a separate effort.

This requires rather deep Linux knowledge to assemble and manual fiddling with syscalls for now to do something useful.

I am not going to target the R-Pi bare metal...

There are other ARM boards that basically resemble oscilloscope + function generator :-)

Yes. And you can get VFX Forth for ARM Linux from MPE. It's the full
VFX Forth for x86 Linux ported to ARM.

I do. The rPi is running a lightsystem controlled by a web-server under Gforth.
