(...) The changes between 1.03 and 1.04 are far more extensive than the changes from 1.04 and 1.05, if you lump the support for ADPCM compression into a single change (which involves c_sound.c, d_sound.c, d_sound.h, d_sound.r, d_sound_adpcm.r, and (...)

Hi T.C. (...) aha. I just programmed some startup and interrupt wrapper code (the rest is C), so I didn't get into the higher reaches of macros etc. Jürgen (17 years ago, 16-Oct-07, to lugnet.robotics.nxt.nxthacking)

Hi Juergen, Thanks for replying. (...) Thanks for the info. My goal is to run and debug ARM assembly language programs executing in RAM.

Hi T.C., (...) I have an AT91SAM7S-EK here, it has 4 LEDs and 4 touch buttons. It should also be fairly easy to write a driver for one of the serial ports (polling would suffice for a start).
