CEL MC13224 Evaluation Kit

evarandios — Tue, 09 Jun 2009 18:48:39 GMT

I'm testing CEL MC13224 evaluation kit and I have several questions:
What changes should I introduce to use the MAC 802.15.4 of Freescale Codebase and to continue using the extern PA? When I modify the MAC codebase gerated by BeeKit whit the changes of CEL plugin I get worse values of LQI.
How can I enable the external PA in the evaluation target with the MAC Codebase Source?

Evandios,

I would recommend you send your question to CEL as they are the manufacturer of this module.

They should be able to tell how to use the module.

Evandrios......

If you are refferring PA as the Power Amplifier Just consider this....

PA is PTD2

RxSwitch is PTD1

TxSwitch is PTD0

On use....... write this values onto the ports:

Tx PA_EN=1 Tx_EN=1 Rx_EN=0

Rx PA_EN=0 Tx_EN=0 Rx_EN=0

Best regards

Sorry on my last post I did a mistake, please consider this....

Tx PA_EN=1 Tx_EN=1 Rx_EN=0

Rx PA_EN=0 Tx_EN=0 Rx_EN=1

My apologies to any cirmcunstances caused....

Best regards

Marco

I have the same problem!

The settings you refer using MAC codebase are into the file NV_DATA.h

/* Energy detect threshold for determining a clear or busy channel during an Energy Detect operation from the MACA */
#define gCcaThreshold_c          0x39

#define gDualPortRFOperation_c   TRUE
#define gPowerLevelLock_c        FALSE
#define gDefaultPowerLevel_c     gAspPowerLevel_3dBm //hex: 0x11
#define gEnableComplementaryPAOutput_c    FALSE

#if gTarget_UserDefined
/* User defined tuning values */
#define gXtalCtuneValUserDefined_c      0x04
#define gXtalFTuneValUserDefined_c      0x0E
#endif

The MAC stack drives internally this signals. But with this settings I can't reach the best tx power.
