Hi,
I know this is off topic, but I haven't access to news to post
to comp.os.linux.*
So, if somebody can help me, please!
I writing a little program to operate a frame grabber board
(it's a Targa+ 32 - 1MB - ISA). So far, I can access the board's register
trough the i/o macros (outb, inb, etc) without problems.
Now, I would like to access the board's memory. The Targa hardware
tech. manual says that the "Targa+ memory appears within the hosts memory
space." and the base address for the VRAM (Targa+) is determined from
a specified field.
I'm not a expert in this kind of programming and I'm lost with
this. I had tried several kinds of pointers addressing/indirections,
mmap'ing the memory using the manual info for determine the start address
but I didn't succeed.
Some help? Please!
If somebody can help me, I can send more details, like
some lines of code, etc.
[]s,
