actually for programming in CCS we know C commands to write a program
but to write in the RTOS in ccs i have to know how to configure the tasks and run them..... some more simple and difficult example programs.................
 i studied the example program but i need some more example programs |

I will try at my home and i will update to you soon.
My suggestion is to create in the same site where you posted the RTOS..... for different compilers so that many can go through them............ it will be good for beginners like me. 
I will update you soon brother. |

What is the advantage to use OSA instead of the built-in in RTOS from CCS?
thanx Holger |
Actually, I did not work with CCS RTOS, so I can't compare these OSes rather competently. But in two word:
Advantages:
1. OSA requires less RAM and ROM.
2. In OSA task may have a priority. When there are several ready to work tasks, scheduler gives control to most priority task.
3. OSA have more services and system objects. The are:
- Binary semaphores
- Counting semaphores (present in CCS RTOS)
- Simple byte messages (present in CCS RTOS)
- Pointers to messages
- Queues of simple messages (present in CCS RTOS)
- Queues of message pointers
- User timers
- Flags
- Critical sections
4. In OSA task can wait an event with timeout breaking
5. OSA doesn't need any PIC's peripherals for itself purposes (CCS RTOS needs a timer)
6. OSA is rather well documented. (As I think )
Disadvantages:
1. OSA doesn't support 12-bit and 16-bit controller under CCS compiler.
2. Firstly OSA was adapted for HTPICC compilers, so several solutions for CCS compiler are not optimal.
3. Too little people works with OSA, so I haven't enough bug reports to improve it (or to fix bugs if they are present)
(I did not test speed characteristics because these two OSes are rather different.)
I think you should try both RTOSes to choose your favorite.
Last version.
Documentation.
Good luck! |

Hello tester
I am currently using CCS 4.104 version, OSA RTOS can not seem to work properly on this version.
In the osa_ccs18.c:
_OS_SET_FSR_CUR_TASK ();
_OS_SET_FSR_CUR_TASK_W (OS_CODE_POINTER_SIZE);
_OS_CurTask-> Timer = Delay;
ERROR: Previous identifier must be a pointer
In the osa.c:
if (! Task-> State.bEnable)
Task-> pTaskPointer = TaskAddr;
Task-> Timer = 0;
* ((OS_TASKS_BANK char *) & Task-> State) = priority;
ERROR: Previous identifier must be a pointer
other:
OS_Run ();
ERROR: Previous identifier must be a pointer
Able to solve the problem? |

Hello again!
Just now I have installed demo version 4.102 (there is no 4.104 demo). It supports PIC18F458 only. The example from OSA\EXAMPLES\CCS\lights_cc18.mcp was compiled with no errors (I only changed chip include file to "#include <18F458.h>" at the begin of file).
What OSA version do you use?
What chip?
Did you create you project correctly?
If you did, then please describe a problem more detailed (show me a texts of program, content of osacfg.h file). |

Unfortunately, I can't check it at v4.104. But all pointed by the compiler lines are written by all C-rules, they contain no errors. Are you sure you did not modify OSA sources? Compiler gives errors on access to _OS_CurTask variable. It should be defined in osa.c:
| Code: |
OST_TASK_POINTER NEAR _OS_CurTask __osa30_near; // Pointer to current task
|
Where type OST_TASK_POINTER is defined as:
| Code: |
typedef OS_TASKS_BANK OST_TCB * OST_TASK_POINTER;
|
in osa.h file. Thus variable _OS_CurTask is defined as a pointer.
(definitions NEAR, __osa30_near, OS_TASK_BANK are empty for CCS compiler)
Try to download OSA again, or try some previous versions. |

My friend just now checked OSA with new 4.104 version and he confirmed these errors. OSA really does not compile under 4.104. I will work on this problem and try to solve it as soon as possible.
Thank's for bug report again. |

Hello,
I just wanted to start trying OSA and have read about this problem. Is this bug fixed again, as I just bought the new ccs Compiler?
Thanx |
