Say a valid byte is 0x55.
I recive one.
How can I confirm that I have got 0x55 due to calibration tuning and not an error.
So what I am trying to ask is can there be a possibilty that when AVR is not calibrated it could recivie a 0x55 just once. |

Where can I find the current calibratin function, as I can see a assembler file but I can see where its called.
Is there a doc or guide, showing how I compile the hal as i belive this can not be done using avr studio. |

Implement some kind of confirmation protocol. |

halCalibrateInternalRc() in Components\HAL\avr\atmega1281\common\src\calibration.c

There is no document for this. You need to run "make clean all" from the command line in HAL directory. |

When you say HAL directory. I guess you mean the top most level inside the HAL folder.
I guess I must also disable the ASYNC clock as well. Can this be done via a flag or do I need to comment out lines, |

Yep.

I think code comments will be necessary. Also keep in mind that async. timer is used during sleep, so your device won't be able to sleep. |

This problem is only on the cord board. Worst case, I will disable it only for the cord. MY Router and End are working well with the a 32Khz.
Is it possible to compile the HAL so that calibration function and async enable function can be executed outside SYS_SysInit() and then called from the bitcloud project enviroment.
This way I can have two extra function, so that I do not need to keep re compiling when I jump from cord to end. |

| For initialization from HAL_Init() call function defined in the application and define this function differently for different devices. |

| But how is this function called from the Bitcloud project file? I am only calling SYS_SysInit() |

| SYS_Init() calls HAL_Init(). |

Silly Question.
Say I have a flag in my application area called calib_flag, so if I place the extern before this in the HAL file, will it be accessble. |

Where Can I find the place in the HAL that let me select the define to set timer2 as a syn or async?

| Timer2 is used for sleep modes, it is not configurable. |

| What about in the Cord device. I would like it to be in Sync. At the moment its Async as its depending on the 32Khz. |

| Then you'll have to change the HAL code to support whatever you need. |

| What problems could happen if the timer2 is sync. Can there be an timing issues. I can also use 8Mhz for more accuracy, |
