Hi,
I have a Bluchip PIO-48 board which consists
of 2 8255 I/O chips I/O mapped at 0x300 (PORTA)
etc.
I have set the ports to Inputs but I'm gettting
weird results with byte = inp (PORTA) instructions.
Does anyone have any experience of using these
boards or with using the inp() functions for
direct IO ?
Cheers"
