cc1310 go to standby and wake up by interrupt I/O

Have you looked if you can use parts of the pinStandby example in TI-RTOS?

Dear TER,

Thank you for reply

Yes, I have looked Pinstandby example in Ti RTOS.

But in my project, I wanted cc1310 goes into standby until it is woken up by I/O interrupt. it means that cc1310 wake up independent time.

at the moment, I made it go into standby with current 1uA when I used Power_sleep(PowerCC26XX_STANDBY) .

But my problem is that I did not wake up it

Thanks,

Thanh

Hi Richard,

I have looked that thread and I tried to used it but its is too high

could you give me some example about low power mode of CC1310?

Best regards,

Thanh.

Dear Thanh,

your question is too unspecific. In the referenced thread, I have compressed what application developers need to know about power management, especially in this answer. If you want to understand the power management, have a look into the official documentation. It may take some time and effort to understand, but please invest it. If you have a specific question, for example to understand a piece of code or a concept, then I can help you.

Hi Richard.

Thank you for reply!

I tried to use " Power_setDependency(PERIPHERAL);
Power_releaseDependency(PERIPHERAL);"
and
"Power_setConstraint(POWERCC26XX_SB_DISALLOW);
Power_releaseConstraint(POWERCC26XX_SB_DISALLOW);"

but current is still too high about 5mA when I transmit RF data.

blow, This is my code

/***** Function definitions *****/
void TxTask_init(void)
{

Task_Params_init(&txTaskParams);
txTaskParams.stackSize = TX_TASK_STACK_SIZE;
txTaskParams.priority = TX_TASK_PRIORITY;
txTaskParams.stack = &txTaskStack;
txTaskParams.arg0 = (UInt)1000000;

Task_construct(&txTask, txTaskFunction, &txTaskParams, NULL);


}

static void txTaskFunction(UArg arg0, UArg arg1)
{


if (PIN_registerIntCb( buttonPinHandle , &buttonCallbackFxn) != 0) {
System_abort("Error registering button callback function");
}

RF_Params_init(&rfParams);

RF_cmdPropTx.pktLen = PAYLOAD_LENGTH;
RF_cmdPropTx.pPkt = packet;
RF_cmdPropTx.startTrigger.triggerType = TRIG_ABSTIME;
RF_cmdPropTx.startTrigger.pastTrig = 1;
RF_cmdPropTx.startTime = 0;

/* Request access to the radio */
rfHandle = RF_open(&rfObject, &RF_prop, (RF_RadioSetup*)&RF_cmdPropRadioDivSetup, &rfParams);

/* Set the frequency */
RF_postCmd(rfHandle, (RF_Op*)&RF_cmdFs, RF_PriorityNormal, NULL, 0);

/* Get current time */
time = RF_getCurrentTime();


while(1)
{
if(status==1)
{

Power_setConstraint(PowerCC26XX_SB_DISALLOW);
Power_setConstraint(PowerCC26XX_IDLE_PD_DISALLOW);

/* Create packet with incrementing sequence number and random payload */
packet[0] = (uint8_t)(seqNumber >> 8);
packet[1] = (uint8_t)(seqNumber++);
uint8_t i;
for (i = 2; i < PAYLOAD_LENGTH; i++)
{
packet[i] = rand();
}

/* Set absolute TX time to utilize automatic power management */
time += PACKET_INTERVAL;
RF_cmdPropTx.startTime = time;

/* Send packet */
RF_EventMask result = RF_runCmd(rfHandle, (RF_Op*)&RF_cmdPropTx, RF_PriorityNormal, NULL, 0);
if (!(result & RF_EventLastCmdDone))
{
/* Error */
while(1);
}
status=0;

Power_releaseConstraint(PowerCC26XX_SB_DISALLOW);
Power_releaseConstraint(PowerCC26XX_IDLE_PD_DISALLOW);

}

}
}
void buttonCallbackFxn(PIN_Handle handle, PIN_Id pinId)
{

if (!PIN_getInputValue(IOID_11)) {
status=1;
}

}

/*
* ======== main ========
*/
int main(void)
{

PIN_init(PinTable);
/* Construct heartBeat Task thread *
IOCPortConfigureSet(IOID_11,IOC_PORT_GPIO ,0x30054000);
/* Open LED pins */

buttonPinHandle = PIN_open(&buttonPinStatus, buttonPinTable);

TxTask_init();

System_printf("Starting the example\nSystem provider is set to SysMin. "
"Halt the target to view any SysMin contents in ROV.\n");
/* SysMin will only print to the console when you call flush or exit */
System_flush();

/* Start BIOS */
BIOS_start();

return (0);
}

in my code, if I did not used
Power_setConstraint(PowerCC26XX_SB_DISALLOW);
Power_setConstraint(PowerCC26XX_IDLE_PD_DISALLOW);
its current is low about 10uA ,that I wanted to achieve. But it goes to standby and when an interrupt to wake up , its RF did not occur again

I want to achieve that my project has a lower 10uA current and use RFcore.

Do you understand my problem?

Thanks and best regards,

Thanh

Hi Richard,

Thank you for your help.

now, I only want my project goes to standby whith 1uA and wake up .

My project has used spi, RF, I/O interrupt.

Best Regards,

Thanh.
