Hi "I INTEND TO USE THE CCSC C COMPILER TO PROGRAM A 16F877, DOES ANYONE KNOW WHERE I CAN FIND EXAMPLES OF C CODE FOR THIS COMPILER. THERE HAS BEEN A LOT OF DISCUSSION RECENTLY USING A HITEC C COMPILER ON THE LIST, CAN I USE THE SAME CODE WRITTEN USING THE HITEC COMPILER FOR THE CCSC COMPILER." There are some examples at "http://www.ccsinfo.com/examples.html" and AFAIK you cannot use exactly the same C source written for the HiTEC C compiler as (at least) I/O handling is different. Also, CCS supports a lot of "built in" functions which HiTEC does not. Maybe you could wrapper things so they would work in either compiler - I have not tried or used the HiTec sufficiently to say one way or the other. I've used the CCS C compiler to build small applications and found it to be very useful and increased productivity somewhat; I'm not sure how "good" the inbuilt functions are in terms of size as it is not possible to see the code they generated. I have also tried the HiTec compiler but was put off as it is initially more time consuming to do things due to the lack of driver support compared to CCS C. An opinion based upon my laziness (well, lack of time) is perhaps not the most objective, though ;-) Regards, Dan -- http://www.piclist.com hint: The PICList is archived three different ways.
