PICos18 porting to CCS compiler

[xgnetto]

Hi, somebody can port successfully picos18 to compile with ccs pic compiler ?

hi friend,

Seems to be difficult, but why don't you start by using the included CCS RTOS functions ?

CCS RTOS is cooperative multitasking, i must make a project with preemptive multitasking.

I doubt there is somebody able to easily port PICos18 to CCS, it's too complex problem. Even the author of the system wasn't able to port PICos18 to Hi-Tech PICC-18, which is from my point of view more compatible with Microchip C-18, see:

Anyway, good luck if you try to do that.

Why to port it since
1- it already works fine under C18 from Microchip
2- C18 is better compiler and by far less buggy than CCS compiler
3- Even if you arg that CCS has more drivers, most of them will be not usable with the preemptive kernel since they use blocking schemes that are mostly incompatible with RTOS logic. And in another way, I think that PICOS018 provides already a very nice set of drivers that respects PICOS18 preemption strategy, and it's easier to translate CCS drivers to C18 instead of PICOS18 to CCS.

hi friends,

xgnetto, ok now i understand your needs but i think bluex is right, using ccs (with a new preemptive kernel) you'll need to re-write all the drivers . Using C18 seems to be simple.
