rfm69模块listen mode模式低功耗应用示例

RF_DK_PIC16MPLABIDEv8.86的软件Listenmode模式是一种侦听模式，软件设置模块的侦听周期，在此周期时间内，模块大部分时间处于低功耗的Idle空闲状态，小窗口时间处于Rx的接收状态，去周期为2.66S，Idle---2.62S;Rx 41mS;RxStarttimeout--16*16*Tbit；如图示：发射周期要大于Listenmode的侦听周期时间。编译后直接下载至MCU中，上电即进入正常的Listenmode侦听模式状态：模块的发射频偏；“BW”代表了模块的接收带宽设置。HopeRF53147“HopeRFRFM#include"rfm69_demo1.h"#include"LCD.h"void{ //delayforstabilizeTypeID=0x69;FreqSel=rfm_br=rfm_pwr=rfm_fdev=RxStatus_F=TxStatus_F=rf69_dp_rxcount=0;{ //Tx{}else //Rx{ //doesreceiveonepacket{RxLimtTime=0;} //overtimestopBuzzer //ifkeypress,changetoTx{RxLed=TxStatus_F=TxLedCnt=TxLedTime=rf69_dp_rxcount=}} //defaultstatuschangetoRx{RxStatus_F=RxLed=TxStatus_F=0;}}}constwordRF69FreqTbl[5][3]={0x0000,0x0000,{0x074e,0x08c0,0x0900},{0x076c,0x0880,0x0900},{0x07d9,0x0800,0x0900},{0x07e4,0x08c0,0x0900},constwordRF69ConfigTbl[21]=FSKDisable //closeclkoutandsetDIO4 //RegPreambleLsb2Byte //enableSync.Word DisableCRC，NRZencode 21bytesforlength&Fixedlength Normalsensitivity ImprovedDAGC 进入StandbyconstwordRF69RxTable[5]= //RegPaLevelFifoInfor //DIOMappingfor //Normaland //Normaland //Entryto{ //Normaland //Normaland //EntrytoconstwordRFM69ListenTable[6]= //Idleresolution262mS,Rxresolutiontime4.1ms //Idletime2620ms //Rxtime // //|totalRxtime constbyteRFM69Data[]={"HopeRFRFMCOBRFM69- **Function：SetRFM69entry **Output："0"forErrorvoidRFM69_EntryListen(void){byte //configRFM69base //calibrationRC } **Function：SetRFM69close **Output："0"forErrorvoidRFM69_CloseListen(void){} **Function：SetRFM69open **Output："0"forErrorvoidRFM69_OpenListen(void){/*bytei;} **Function：SetRFM69entry **Output："0"forErrorbyte{byte //configRFM69baseparameters //waitforentryRx{ } //overtimefor //now,entryin} **Output："0"forErrorbyteRFM69_EntryTx(void){byte //closethelisten(change) //configRFM69baseparameters //configRFM69TxModeparameters ///waitforentryTx{ } //overtimeforerror //now,entryinBurstWrite(0x00,(byte*)RFM69Data,21);//SendfirstPacket //returnOK}} **Function：ChangetoRxModefromStandbyMode,canclearFIFO **Output：voidRFM69_ClearFIFO(void){ //EntryStandby //ChangetoRx} **Function：SetRFM69tosleep **Output：voidRFM69_Sleep(void){ //forceto} **Function：SetRFM69toStandby **Output：voidRFM69_Standby(void){ //forceto} **Function：InitializeRFM69&setitentrytostandby **Output：voidRFM69_Config(void){bytei; } **Function：Checkforreceiveone **Output： Receiveone NothingforbyteRFM69_RxPacket(void){bytei;{rf_rssi_value=SPIRead(0x24);RxData[i]=0x00;SPIBurstRead(0x00,RxData,
