FULL ANSI C

[Guest]

Please help on this topics :

1.) Can i write full ANSI C program in CCS C compiler

2.) Can i skip ready made functions and and use standard ANSI C approach.

3.) Can i port my CCS code ( written fully in ANSI C ) to other MCU ?

1) No, this is not an ANSI C compiler, it predates ANSI C. It is close to a Kernighan & Ritchie C compiler but it has some changes to fit on small processors. For example the Int is 8 bits, which follows the original K&R idea that the Int should be the natural data width of the processor. Using 16 bit math would introduce too much overhead for common use.

2) You can skip the ready made functions and use C or assembler. People do it all the time. But the strong point of CCS is the ready made functions.

3) Few other MCU C compilers are ANSI compliant either. So porting code from one compiler to another is generally a pain.
