Hi there,

I spent the last 2 weeks trying to figure out why sometimes my solution seems crashing.

I have followed as much as possible all the recommendation from Cypress...

My main loop looks like:

    for(;;){

        // process the BLE events in the stack

        CyBle_ProcessEvents();

        /***********************************************************************

        *  Put BLE sub system in DeepSleep mode when it is idle

        ***********************************************************************/

        ManageBlePower();

        /***********************************************************************

        *  Run your application specific code here

        ***********************************************************************/

       // if(applicationPower == ACTIVE)

        {

            RunApplication();

        }

         /***********************************************************************

        *  Process application power modes

        ***********************************************************************/

        ManageApplicationPower(); 

        /***********************************************************************

        *  Manage system power mode based on application and BLE power modes

        ***********************************************************************/

        ManageSystemPower();

    }

the systems has 2 interrupts :

interrupts # 1 => WDT (every 250 msec)

Interrupt #2 => external pin (Pin 1.1)

What I notice is that sometimes after I have pressed the button the system seems to crash.

Most of the time I see an LED  going off (e.g. Green LED is gets on) and then the systems don't respond anymore.

with the oscilloscope I have noticed (in my last test this evening) that when it crashes the 24 MHz is ON for ever, draining all the battery.

Can someone have a look at the code please and tell me what I'm doing wrong please?

Thank you,

Francesco

I found the discussion "

PSoC4 and PSoC4 BLE IMO accuracy With API-called calibration

" but it is locked.

It pointed to http://www.cypress.com/documentation/code-examples/ce97601-improving-accuracy-psoc-4-internal-main-oscillator

but that documentation says it is obsolete.

Is there a way to calibrate the IMO to get better than +/-2% precision

or

is there a way to know the exact frequency of the IMO even if it is within the +/-2% range so that FW can compensate for it by changing counter values?

Thanks,

Ofer

I've been told by a Cypress application engineer that the PSOC 4700 can be used to measure the DC current flowing through a wire.  I have read all available information about inductive sensing with the PSOC 4700 but nowhere does it explain how to do current sensing.  Can someone explain to me how I can use the psoc4700 to measure a current through a wire and/or send me an application note explaining how to do it?  Thank you.
