// Make Port A bit-wide output
BitWrPortI( SPCR, &SPCRShadow, 1, 2 );
BitWrPortI( SPCR, &SPCRShadow, 0, 3 );
Obviously SPC is some kind of configuration port… I want to make sure PB is setup the same… I’ve looked through all the PDFs I have including the 5700UM and I don’t see any documentation on what these special registers do.
However I have document RC5700UM.pdf 2.8 mb in size. I’ve read every page and I see NOTHING on that register or any of the special registers. Do I have the right document? Is there a page I’m somehow missing when I press next, next, next in my PDF viewer?
This document covers the layout of the boards, how to install the 5700 module. How to connect cables, install Dyn C, run a few sample programs and it gives a list of features. There is nice pinout of the 5700 module. But I see nothing that gives me these registers, what they mean, etc… There is good coverage of the boards in the deluxe development kit.
For example with this manual I would not have a clue how to enable serial communication on a particular set of pins. I can and have looked at the myriad sample programs but like in the code in my first post there is often a short comment but nothing else about use of a particular register.
I found this also to be true regarding the rabbit web stuff. I could find nothing in help on the “SSPEC_RESOURCE_…” stuff. I was able to accomplish what I needed by playing around.
Thank you for the hint on how to turn PB in outputs… That is what I want to do. But rather than ask dumb questions… where do I find the documents I need?
I’ve done a load of MicroChip programming and I have to say that when I down load a PDF of a particular model chip I have EVERYTHING that I need to program that chip for every possible mode.
I realize the 5700 is more complex and maybe requires several PDFs… but they should be available easily. When I go to the RCM5700 product page I see a Data Sheet, Users Manual (same as I have), Schematic, Dyn C manual. It seems and I hate to say this because I really like the modules, poorly documented by comparison.
Just to be sure I was not going crazy I downloaded the 5700 UM from the product page and read it again. Nothing on SPCR… In fact nothing I could find at all about how to configure the various features of each port. I have to assume this is the “users guide” and somewhere there is a true “manual” that documents all of this stuff. But where!?
