migrating from PIC18 -> PIC24

OneOff · Guest

Just a few general questions about migrating a project from the PIC18 PCH compiler to the PIC24 PCD compiler.

1. Choosing a 24 series chip that runs '40MIPS' will generally run my 18F code 4x faster that the 18F2550 chip I am using now?
2. Is the CCS MachX able to program the 24 series ICs in the ZIF socket, and ICSP?
3. Is the PCD compiler ready for prime time yet? I still see many complaints about it still being in the beta stage
4. None of the 16-bit PICs have pre-emptive processing available, correct?

Thanks in advance

Anyone?

Maybe just an answer to #1 if nothing else?

Thanks

Hi,

Depending on the algorithm you will get much faster results. A PIC32 running at 80mhz run 28 times faster than a pic18 at 40mhz on one of my project.

This post has benchmarks for various PICs for floating point operations,
though not for the PIC24:
