I'm finally going to start really using a higher (than 8-bit) PIC and =20 also looking into Atmels and C instead of assembly (for the PIC too). =20 Since there will be optimizations, how would timing-specific code =20 (such as bit-banging) be done? Are these pieces put into inline =20 assembly, or is there a way to use C code with known timing?
