|I'm running a SCO OpenServer Unix, and want to access ( read and write ) directly ( bit level ) in a memory address who is assigned to the parallel port, and get control of that port and the device how is attached to it, which is a PIC microcontroller.|
The C language included in my OS, has not some libraries that are common for windows, so I need find one that is normally found in a Unix enviorement, or one that is portable to Unix, and bring a function or command to read and write direct a bit in a specific memory address.
I have been working with "read()" and "write()", but these don't let me select a memory address as input or output, or I am missing something with these ones ??
The _inp() and _outp() I can't find them in my libraries, equal for inportb() and outportb()
Any help will be appreciate
