Hi all!
I've just written a LCDproc driver for my VF-Display which is connected
to the parallel port and now I need a possibility to read in some information
via the same parallel port from a microcontroller, which scans a keypad matrix
the whole time (and perhaps doing more stuff). The driver gets direct access
to the ports (0x378 etc.) using ioperm. Data is transferred through
the data lines (D0-D7) in combination with four output lines (/strobe, /LF
etc.)
As I don't want to poll one input line of the parallel port the whole time, I
plan to use the /ack input in combination with an interrupt! Is this
possible at all using direct access? I searched a lot of sites, but didn't find
the right information. Can someone help me?
Thank you in advance!
Best regards,
Sven Lübke
