MSP430FR2675: FR2675 to detect moisture

Hi,

1. It is a very interesting application. Can you tell more details that how customer use CapTIvate to detect moisture?

2. If I understand is right that customer want to set the value go back to LTA. I think they can try     MAP_CAPT_calibrateUI(&g_uiApp);

Hi Eason,

Sorry for late reply. I couldn't reply you because of my non-company email. I just changed it into my company's email.

1.I'm not very familiar about the hardware. currently I just check the value of tElement.bProx to determine if the device detect moisture.

2. I have already tried " MAP_CAPT_calibrateUI(&g_uiApp);", it didn't work. It would reboot my device.

Here is my code:

void capcitive_data_cb(tSensor* pSensor)
{
tElement** ppEle = (*pSensor->pCycle)->pElements;
tElement* pEleK = ppEle[0];
tElement* pEleG = ppEle[1];
gRawCountK = *pEleK->pRawCount;
gRawCountG = *pEleG->pRawCount;
gProxG = pEleG->bProx;
gProxK = pEleK->bProx;
}

int main()
{
MAP_CAPT_registerCallback(&BTN00, &capcitive_data_cb);
CAPT_appStart();
for(;;)
{
...
CAPT_appHandler();
CAPT_appSleep();
...
if(gProxG||gProxK)
{
//do something
//reset "pEleK->bProx" and "pEleG->bProx"
}
}
...
}

the line in red is what I need

Why customer want to reset the Proximity flag?

Actually For pEleK->bProx" and "pEleG->bProx", it will be updated when calling CAPT_appHandler(). As the device detect there is a proximity signal, it will update the proximity flag. As a result, even you reset the proximity flag, it will still be set when calling CAPT_appHandler() again.

If customer only need to reset the flag, they can create a new flag by themselves.

Because when I touch the panel, the proximity flag will be set to true by library, but after I remove my finger from the panel, the proximity flag is still true. I want it can be set to false.

Does it still remain true after you remove your finger far away from the pannel?

Do you touch it for a long time?

Can you use the data logging function to record the data and post it on e2e?
