CC1352P: 如何在应用中校准RTC

ea skk — Thu, 10 Sep 2026 01:27:46 GMT

Part Number: CC1352P

使用PowerCC26XX_injectCalibration校准rtc，校准前后AONRTCSubSecIncrGet()获取到的值没有变化，怎么才能在应用中校准RTC

static void measureRtcAccuracy(const char *tag)

{

uint32_t start, stop, delta_actual;

uint32_t subsec_incr;

float freq, ppm;

char msgBuf[160];

subsec_incr = AONRTCSubSecIncrGet();

sprintf(msgBuf, "[%s] subsec_incr=%lu, \r\n",

tag, (unsigned long)subsec_incr);

uartPrint(msgBuf);

}

void *mainThread(void *arg0)

{

UART2_Params uartParams;

GPIO_init();

AONRTCEnable();

UART2_Params_init(&uartParams);

uartParams.baudRate = 115200;

uartParams.writeMode = UART2_Mode_BLOCKING;

uartHandle = UART2_open(CONFIG_UART2_0, &uartParams);

if (uartHandle == NULL) {

while (1);

}

Power_setDependency(PowerCC26XX_XOSC_HF);

uint32_t timeout = 5000;

while (!PowerCC26XX_isStableXOSC_HF() && timeout--) {

ClockP_usleep(1000);

}

if (timeout == 0) {

uartPrint("XOSC_HF not stable!\r\n");

} else {

uartPrint("XOSC_HF stable.\r\n");

}

while (1) {

measureRtcAccuracy("before");

bool calStarted = PowerCC26XX_injectCalibration();

char infoBuf[64];

sprintf(infoBuf, "injectCalibration: %s\r\n", calStarted ? "started" : "failed");

uartPrint(infoBuf);

ClockP_usleep(CALIBRATION_WAIT_US);

measureRtcAccuracy("after");

uartPrint("-------------------\r\n");

ClockP_usleep(500000);

}

return NULL;

}

CC113L: CC113L--Enabling Manchester decoding results in a decrease in reception success rate.

wenyuan gong — Thu, 13 Aug 2026 08:04:22 GMT

Part Number: CC113L

Configuration supplement：Base Frequency（433.00MHz）Deviation（39.6kHz）Data Rate（19.2 kbps--After encoding, 38.348.）Modulation Format（2-FSK）Encoding（Manchester）Preamble（(0x5555 5555 5555)）Sync Word（0x569A）

When I configured CC113L with the following parameters, the laboratory test showed that the reception rate was close to 100%.
NRZ code reception, reading data from the FIFO, Manchester decoding is processed by software.

After enabling the Manchester decoding of CC113L, the reception rate is approximately 70%. The configuration is as follows.

CC1310: 50k速率下的信道间隔多大合适

Part Number: CC1310

HI ，

我现在想使用CC1310开发868M频段，使用smartrf studio 里面 50K的默认射频配置，按照这样的配置，两个信道之间间隔多少khz，比较合适呢？

Thanks!

RE: CC1310: 50k速率下的信道间隔多大合适

Vivian Gao — Tue, 04 Aug 2026 01:19:17 GMT

我们从经验来建议，没有对比数据，您可以自行调整比对。

在实际环境中测试信道间干扰，必要时可以调整间隔。

RE: CC1310: 50k速率下的信道间隔多大合适

ruimao cong — Mon, 03 Aug 2026 08:56:45 GMT

RE: CC1310: 50k速率下的信道间隔多大合适

Vivian Gao — Mon, 03 Aug 2026 08:36:17 GMT

200 kHz频道间隔是最优选择，它能提供出色的邻道抑制，同时最大化频道容量

RE: CC1310: 50k速率下的信道间隔多大合适
