Hello all,
I'm working with a friend of mine in the Robotics lab at the UofM
to try to interface a Miniboard with a Handyboard through the SPI bus.
We're having a fair amount of troubles trying to do it through
interactive C. I figure we'll have to write our communications files in
assembly and work with them through .icb files but I'm not entirely sure.
Therefore, I submit the following message from John to the list in hopes
that someone might help lead us in the right direction.

Fred,
I am trying to run the serial peripheral interface (port D2-5) from
interactive C. There seems to be a problem. When I do this:
poke(0x1028, 0x5c);
peek(0x1028);
the returned value is 0x0c NOT 0x5c. I cannot set the SPE bit nor the
MSTR bit. This means that I cannot communicate to another board through
the synchronous serial port. How can I set these bits while running
interactive C? Is it possible or do I have to use some other technique?
John

| (...) I'm pretty sure that files assembled this way will work with the freeware IC as well. Please note one big GOTCHA with ICB files. On the MS-DOS platform, the ICB files must have Unix-style line termination. OK, what does that mean. In a text (...) (29 years ago, 15-Apr-96, to lugnet.robotics.handyboard)
