My NVRAM is a serial flash connected to SPIFFY1. To protect my system I want to read Unique ID Number from sflash.
How can I access this data using SPIFFY1 interface ? Since SPIFFY1 has limited availability for application use is it possible at all ? How can I assert CS since this pin is not accessible from application ? Is it always asserted ?
Show LessHi,
I am using RTC function in BCM20737S to do a wakeup call in my design to activate some activities and then goes back to deep sleep again.
I use an external 32K LPO, that allows the RTC can wake up at anytime from 128ms to approx 144 hours.
However the sleep time of my design will be longer than 144 hours, that means once the device goes to deep sleep, it could wake up at a time that is longer than 144 hours.
How can I make the wake up time longer than 144 hours without wake up the device at every144 hours, say, to reload the RTC clock to run again.
If I do that, the device will need to wakeup every 144 hours elapsed for any longer sleep time than 144 hours though.
Please advise.

Show LessHi WICED team,
I am trying to connect external sensors to the TAG4, and the same code that is working fine on TAG 3 doesn't seem to initiate any I2C communication on J9 of my TAG4. I have switches 2 and 4 on SW8 set to OFF, are there some other switches I need to set?
Thanks,
Filipp

Basing on hello_client, customer is developing their own application, however once customer board is powered on, following logs can be found:
ASSERT, , L#0, stat=0x20EF08
ÃASSERT, , L#0, stat=0x20EF08
ASSERT, , L#0, stat=0x20EF08

ASSERT, , L#0, stat=0x20EF08
ÃASSERT, , L#0, stat=0x20EF08
ASSERT, , L#0, stat=0x20EF08
Questions:
1. What's the reason to output those logs?
2. Are there some problems on customer codes? If yes, how to fix them?
Thanks!
Show LessI want to run my BCM920737TAG on external 5v battery supply not the coin cell battery of 3.3v
I will use the converter to convert supply from 5 to 3.3v
but where should i provide the supply connections.
Can i use USB as a supply connection from battery.
Also i need to monitor the status of battery how much % battery is remain ..
How can i do that ?
Show LessWe have previously designed around BCM20732S module and we are about to use the SoC counterpart BCM20732, then I realized that has few IO pins. How is this possible? Is there any multiplexing operation done on the module?
Show LessHow can i use GPIO PULLUP/PULLDOWN for GPIO,
Using the function
gpio_configurePin(2/16, 2%16, GPIO_EN_INT_FALLING_EDGE,GPIO_PIN_INPUT_HIGH);
or which functions i use...
Show LessHi i have a shock sensor & BCM2073X_LE_KIT (BCM920737TAG).
My shock sensor gives high pulse if it detects the shock & i want to configure it as a interrupt ,So what i did is..
#define SHOCK_IN 4
#define SHOCK 8
const UINT8 shk=SHOCK;
& in the following fuction i enabled interrupt
void hello_client_connection_up(void)
{
UINT16 masks[3] = {(1 << SHOCK_IN), 0 , 0};
gpio_registerForInterrupt(masks,(void *)hello_client_interrupt_handler,(void *)&shk);
gpio_configurePin(SHOCK_IN/16, SHOCK_IN%16, GPIO_EN_INT_RISING_EDGE,GPIO_PIN_INPUT_LOW);
}
It works fine when the shock interrupt pin is connected ,but it gives continuous interrupt whenever i disconnect the shock pin.
It should not give interrupt when there is no connection on shock pin..
Show LessHi,
In the changelog of SDK 2.2.3, There's a mention about spectrum growth at 37ch happens while advertising.
With SDK 2.2.2, could the spectrum growth happen with the following APIs as well?
WICED-Smart-SDK\include\blecm.h
void blecm_EndTest(void);
UINT8 blecm_StartReveiverTest(UINT8 channel);
UINT8 blecm_StartTransmitterTest(UINT8 channel, UINT8 packetLength, UINT8 packetType);
rf_cw_test_api.a
UINT8 blecm_EnableUnmodulatedTxCarrierFrequencyTest(UINT16 cwFreq,INT8 txPower);
UINT8 blecm_DisableUnmodulatedTxCarrierFrequencyTest(void);
