cc1310 driverlib 射频初始化问题

时间:12-23 整理:3721RD 点击:

只使用了driverlib中的驱动库,本想测试下命令的交互,顺带发送一个载波信号出来,却不想一直没成功。

。。。。。。

//1. XOSC初始化
PRCMPowerDomainOn(PRCM_DOMAIN_PERIPH);
    while (PRCM_DOMAIN_POWER_ON != PRCMPowerDomainStatus(PRCM_DOMAIN_PERIPH));

    PRCMPowerDomainOn(PRCM_DOMAIN_VIMS);
    while (PRCM_DOMAIN_POWER_ON != PRCMPowerDomainStatus(PRCM_DOMAIN_VIMS));
    
    PRCMDomainEnable(PRCM_DOMAIN_VIMS);
    PRCMPeripheralRunEnable(PRCM_PERIPH_GPIO);
    PRCMLoadSet();
    while (!PRCMLoadGet());
    
    if (OSCClockSourceGet(OSC_SRC_CLK_LF)!=OSC_XOSC_LF)
	{
		OSCClockSourceSet(OSC_SRC_CLK_LF, OSC_XOSC_LF);
	}
    SetupSetAonRtcSubSecInc(0x7FFD40);
    
    if (OSCClockSourceGet(OSC_SRC_CLK_HF)!=OSC_XOSC_HF)
    {
        uint32_t tmp;
        OSCHF_TurnOnXosc();
        while (!OSCHfSourceReady());
        OSCHfSourceSwitch();
        do
        {//check
            tmp = OSCClockSourceGet(OSC_SRC_CLK_HF);
        }
        while (tmp != OSC_XOSC_HF);
    }
//2. RF部分电源与时钟初始化
rf_core_set_modesel();
    if (!PRCMRfReady())
    {
        PRCMPowerDomainOn(PRCM_DOMAIN_RFCORE);
        while (PRCMPowerDomainStatus(PRCM_DOMAIN_RFCORE)!=PRCM_DOMAIN_POWER_ON);
        
        PRCMDomainEnable(PRCM_DOMAIN_RFCORE);
        PRCMLoadSet();
        while (!PRCMLoadGet());
        
        //RFCClockSet(RFC_PWR_PWMCLKEN_CPERAM|RFC_PWR_PWMCLKEN_CPE |RFC_PWR_PWMCLKEN_RFC);
        RFCClockEnable();
        
        //rf_patch_cpe_genfsk();
        clock_wait(CLOCK_SECOND);
    }
//3.命令交互测试
tmp = RFCDoorbellSendTo((uint32_t)&RF_cmdPropRadioDivSetup);
    wait_cmd_done(&RF_cmdPropRadioDivSetup);
    if ((RF_cmdPropRadioDivSetup.status&0x0fff)!=0x0400)
    {
        flag = 1;
        printf("radio setup error-->status=%x\r\n", RF_cmdPropRadioDivSetup.status);
    }
	tmp = RFCDoorbellSendTo((uint32_t)&RF_cmdFs);
    wait_cmd_done(&RF_cmdFs);
    if ((RF_cmdFs.status&0x0ffff)!=0x0400)
    {
        flag = 1;
        printf("Fs cmd error-->status=%x\r\n", RF_cmdFs.status);
    }

当运行到  RF_cmdPropRadioDivSetup时,命令中的status一直为0x02。

同道中人。。。 不过基于DRIVERLIB直接编程,官方不会提供技术支持,相信,这里不会有答案。demo 中的例程有答案。。。

我认为问题在于 RF_cmdPropRadioDivSetup这条命令后面跟随的pOverrides。

具体为什么会这样还暂时不清楚。

修改pOverrides后,发射出了载波信号!

// Overrides for CMD_PROP_RADIO_div_SETUP static uint32_t pOverrides[] = { // override_use_patch_prop_genfsk.xml // PHY: Use MCE ROM bank 4, RFE RAM patch //MCE_RFE_OVERRIDE(0,4,0,1,0,0), // override_synth_prop_863_930_div5.xml // Synth: Set recommended RTRIM to 7 HW_REG_OVERRIDE(0x4038,0x0037), // Synth: Set Fref to 4 MHz (uint32_t)0x000684A3, // Synth: Configure fine calibration setting HW_REG_OVERRIDE(0x4020,0x7F00), // Synth: Configure fine calibration setting HW_REG_OVERRIDE(0x4064,0x0040), // Synth: Configure fine calibration setting (uint32_t)0xB1070503, // Synth: Configure fine calibration setting (uint32_t)0x05330523, // Synth: Set loop bandwidth after lock to 20 kHz (uint32_t)0x0A480583, // Synth: Set loop bandwidth after lock to 20 kHz (uint32_t)0x7AB80603, // Synth: Configure VCO LDO (in ADI1, set VCOLDOCFG=0x9F to use voltage input reference) ADI_REG_OVERRIDE(1,4,0x9F), // Synth: Configure synth LDO (in ADI1, set SLDOCTL0.COMP_CAP=1) ADI_HALFREG_OVERRIDE(1,7,0x4,0x4), // Synth: Use 24 MHz XOSC as synth clock, enable extra PLL filtering (uint32_t)0x02010403, // Synth: Configure extra PLL filtering (uint32_t)0x00108463, // Synth: Increase synth programming timeout (0x04B0 RAT ticks = 300 us) (uint32_t)0x04B00243, // override_phy_rx_aaf_bw_0xd.xml // Rx: Set anti-aliasing filter bandwidth to 0xD (in ADI0, set IFAMPCTL3[7:4]=0xD) ADI_HALFREG_OVERRIDE(0,61,0xF,0xD), // override_phy_gfsk_rx.xml // Rx: Set LNA bias current trim offset to 3 (uint32_t)0x00038883, // Rx: Freeze RSSI on sync found event HW_REG_OVERRIDE(0x6084,0x35F1), // override_phy_gfsk_pa_ramp_agc_reflevel_0x1a.xml // Tx: Configure PA ramping setting (0x41). Rx: Set AGC reference level to 0x1A. HW_REG_OVERRIDE(0x6088,0x411A), // Tx: Configure PA ramping setting HW_REG_OVERRIDE(0x608C,0x8213), // override_phy_rx_rssi_offset_5db.xml // Rx: Set RSSI offset to adjust reported RSSI by +5 dB (uint32_t)0x00FB88A3, // TX power override // Tx: Set PA trim to max (in ADI0, set PACTL0=0xF8) ADI_REG_OVERRIDE(0,12,0xF8), (uint32_t)0xFFFFFFFF, }; // CMD_PROP_RADIO_div_SETUP // Proprietary Mode Radio Setup Command for All Frequency Bands rfc_CMD_PROP_RADIO_div_SETUP_t RF_cmdPropRadioDivSetup = { .commandNo = 0x3807, .status = 0x0000, .pNextOp = 0, // INSERT APPLICABLE POINTER: (uint8_t*)&xxx .startTime = 0x00000000, .startTrigger.triggerType = 0x0, .startTrigger.bEnaCmd = 0x0, .startTrigger.triggerNo = 0x0, .startTrigger.pastTrig = 0x0, .condition.rule = 0x1, .condition.nSkip = 0x0, .modulation.modType = 0x1, .modulation.deviation = 0x64, .symbolRate.preScale = 0xF, .symbolRate.rateWord = 0x8000, .rxBw = 0x24, .preamConf.nPreamBytes = 0x1E, .preamConf.preamMode = 0x0, .formatConf.nSwBits = 0x20, .formatConf.bBitReversal = 0x0, .formatConf.bMsbFirst = 0x1, .formatConf.fecMode = 0x0, .formatConf.whitenMode = 0x0, .config.frontEndMode = 0x0, .config.biasMode = 0x1, .config.analogCfgMode = 0x0, .config.bNoFsPowerUp = 0x0, .txPower = 0xAB3F, .pRegOverride = pOverrides, .centerFreq = 0x0364, .intFreq = 0x8000, .loDivider = 0x05, };

以上是  RF_cmdPropRadioDivSetup命令和pOverrides,

注释掉第一句 //MCE_RFE_OVERRIDE(0,4,0,1,0,0),后,Setup正常。

使用SmartRF Studio 7是能正确操作板子的, 是自己程序中ccfg.c没配置正确吗或者其他初始化代码有问题?
