The
Amélie
project | |
Sorry, no firmware is
available yet - Amélie
has not been
'built'!
The system emulator, AmélieEm, includes a basic
test/development ROM. This has not fledged into a BIOS, it
does little more than initialise the hardware, flash the LEDs
in sequence, and output '!' to the serial port on every ticker
event (which is 50 times a second in reality, so don't try
this on real hardware!).
The following two sources build the default EPROM image that is
supplied with AmélieEm.
amebios.s65
(26K) Basic BIOS code. Doesn't do much other than set up the
hardware, install some rudimentary interrupt handling, and then
call the application code.
For compiling under RISC OS, you will need to amend the
CNT command at the end to call
the application code using the correct filename (which would probably
be "appcode/s6") and
also including a path...
appcode.s65
(2K) Application code, does nothing much, just whizzes the LEDs
in a scan sequence sort like Knight Rider's KITT.
