Ok. Another question from this annoying developer wanting to use
undocumented/supported features...
I have the 3.5 SDK and looked high and low for a header with this sort of
function, and couldn't see it. Then I looked in the older 3.1 SDK and lo
and behold there is Hardware.h which contains (among other things):
typedef enum {
DockStatusNotDocked = 0,
DockStatusInModem,
DockStatusInCharger,
DockStatusUnknown = 0xFF
} hwrDockStatusState, *hwrDockStatusStateP;
and further down...
hwrDockStatusState HwrDockStatus(void)
SYS_TRAP(sysTrapHwrDockStatus);
Now this is close-ish to what was suggested, so for fun, I copied the above
bits to the top of my program's source file and inserted the following line
when my program loads:
while ((HwrDockStatus() & DockStatusInModem) == 0) {}
i.e. loop until a 'modem' is attached. This seemed to work fine: The
program would hold until I connected a 20 Ohm R between VCC and the GPI2
pin on one of my IIIe's.
I assume there is a better/proper way to access this function? How do I --
or CAN I -- get to it in the 3.5 SDK? I didn't define the trap anywhere
(sysTrapHwrDockStatus) so that's there, but I don't know what to include to
get the HwrDockStatus function.
Anyone who can point out the really obvious answer I must've missed, please do!
