Zigbee-CC2530开发板协议栈-改动发射功率

CC2530 控制输出功率的寄存器是 TXPOWER:

推荐功率设置：

协议栈默认的设置是 0xd5,为了扩展信号传输的距离，我把TXPOWER寄存器值改为0xf5, 此时输出功率为4.5dBm.在mac_radio.c文件，做了例如以下改动：

void macRadioSetTxPower(uint8 txPower)

{

halIntState_t s;

/* if the selected dBm is out of range, use the closest available */

if (txPower > MAC_RADIO_TX_POWER_MAX_DBM)

{

txPower = MAC_RADIO_TX_POWER_MAX_DBM;

}

/*

* Set the global variable reqTxPower. This variable is referenced

* by the function macRadioUpdateTxPower() to write the radio register.

*

* A lookup table is used to translate the power level to the register

* value.

*/

HAL_ENTER_CRITICAL_SECTION(s);

reqTxPower = macRadioDefsTxPowerTable[txPower];

HAL_EXIT_CRITICAL_SECTION(s);

/* update the radio power setting */

//************** 自己改动 ******* 

reqTxPower = 0xF5;

//******************************* 

macRadioUpdateTxPower();

}
