ok - a followup.
having found that:
{
const UInt32 bitRate[15] = { 0, 32000, 40000, 48000, 56000, 64000,
80000, 96000, 112000, 128000, 160000, 192000, 224000, 256000, 320000 };
return bitRate[bits];
}
Is triggering an A5 warning, I need to do the same job without globals
(I have turned on PC-Relative strings and PC-Relative constants in the
project options, but they don't seem to fix this)
can anyone suggest an efficient way to do this that won't end up using the
A5 register?
Other than a switch (which seems like a sledgehammer approach) or loading
the data from a resource (slow?), I'm at a loss...
Thanks,
Rob
