To narrow this down a little bit...I have recently acquired the books, software, etc. related to C and C++ on the PC. I am doing the reading and some exercises in an attempt to familiarize myself with the language, so I beleive I am on the right track in that regard. What I need is target specific language reference relating to the dsPIC processors. Most of what I find is compiler specific which does not give me any concept of how to configure the chip in C30 or make use of peripheral functions of the chip. For example, in ASM30 (assembly), one would in general, do the following to place a value into a register: MOV #literal_value, W0 ; move literal value into working register 0 MOV W0, SFR ; move contents of working register 0 to special function register (or any other specified) How are the registers manipulated in C30.....what are they called in C30....are the register names the same as in assembly? I see some C code using #pragma's to do things that other code examples do withuot using the #pragma. It is the target specific info I need. If gleaning this info from includes and header files is required, then that is what I will do. I was curious if there existed any handy reference for these things. Again, all I seem to find is compiler specifics that do not guide one in the use of the language specific to the chip. Thanks again for any replies. -- Regards, Stephen D.
