This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

ReadMe : Enhanced IIC Module v1.01 10 June 1991
============================
This module has been rewritten from scratch to provide the following three
enhancements :-
(a) This now operates much faster, ie as near to the 5us pulse width time
defined by Philips in the full standard as can be achieved in
software on an Archimedes. Exactly how close depends on the model
and processor speed (ARM2 or 3 etc). The design of the software is
constrained by the need to enable interrupts while waiting for
acknowledgement etc as this can vastly exceed the permitted holdoff.
Note that the operation of system interrupts and also DMA for the
sound and video subsystems can slow this down. Also beware that
there may be other constraining factors, such as length of cable,
and the addressed device need not respond instantly anyway.
(b) Secondary addressing is now supported, ie this allows operation
through a bus extender oddule (or equivalent). The standard IIC
bus allows 254 locations unexpanded. Each bus extender uses one
directly addressable location to provide a doorway to a further
254 locations. This version will send out up to four bytes of
device address before proceeding to read or write as requested. The
four bytes are supplied in R0 (as before), the most significant byte
will be sent out first (ie the address of the first extender). Note
that values of zero are ignored and that the IIC dynamic addressing
protocol (which uses address zero to allocate device addresses) is
still not implemented.
(c) There is now an extended form of the SWI call, called
"IIC_ExtendedControl", which takes an extra parameter, in R3, which
is a speed factor (approx 0.5 us increments, in range 0 - 127).
This allows operation over much longer wires - as the capacitance of
the wire increases, the rise and fall times of the signals also
slow down, but if not enough time is allowed for signals to stabilise
at each state then the signals will not be recognised correctly. By
specifying a longer time constant and so effectively slowing the
whole communication down, more reliable operation can happen over
longer distances.
Any bugs found should be reported to Baildon Electronics with full details
of how to get the problem to occur, BUT don't *expect* support for a product
that you have not paid for !
