Features

The CC8E C compiler supports PIC18 instructions (legacy mode) and generates optimized code. The code efficiency that have put CC5X in a leading position for over 15 years also applies to CC8E.

Supports 8, 16, 24 and 32 bit variables, signed and unsigned, single bit variables, compiler generated layout of local variables, automatic ram bank updating. Generates many files (hex, assembly, list, error, function outline, variable list). Supports structures and unions, bitfields, typedef, typecast, arrays and pointers. Plus integrated interrupt support.

Fixed and floating point math is available. The floating point math (16, 24 and 32 bit) includes functions like log(), log10(), exp(), exp10(), sin(), cos(), sqrt(). The libraries are compact and fast. Code can be optimized for size or speed.

The code generated by CC8E can be inspected at the example page.

Linker support: C and assembly modules can be linked together using MPLINK.

Multitasking support using state machines is available.
