Can anyone shed light on why one would or wouldn't choose to use this?

I'm looking at p8 of the BCM20732S datasheet, "32.768 kHz Oscillator (optional)"

Thanks

Hi all, I'm trying to make an eagle part library for BCM20732S for the board I'm designing.

I'm looking at P9 of the BCM20732S datasheet where the layout of the pins is described for the PCB stencil.

I'm a bit confused about the positioning of pins "C" - are they centred on the centre of the chip? Judging from the position of pins "A" and "B", pins "C" are centred (0.25,0.25) mm from the centre of the chip and are 1.25mm apart from each other, but the drawing doesn't show this explicitly. Is this drawing available in any cad format, or is there even a part library?

I'm happy to share the eagle part library once I finish it.

I have looked around in the SDK and I can't find a way to discover my own address, only that of a peer.

Is there any way to get my own MAC address?

Following instructions from "WICED Smart™ Hardware Interfaces" I tried this simple program:

#include "gpiodriver.h"

void application_init(void)

{

  // Initialize the GPIO driver.

  gpioDriver_init();

}

I am getting the linker error:

undefined reference to `gpioDriver_init'

Does anybody know where the implementation of this function is ?

Thank you

Hello,

I would like to test my WICED SMART card with an Android cellphone with the example codes and apps provided. The user guide uses LightBlue App in an Iphone and the heart rate monitor app in the WICED board in order to test functionality. Please provide similar test that would work for an Android smartphone that is bluetooth LE capable.

I connected WICED SMART and attempted to run example code provided but I keep getting the following error (shown at the end of the log below). Please advice.

I have setup the fine timer (in the context of the heart rate monitor application) to write a command byte to SPIFY2 and then read back 4 bytes.  This seems to work accept for the fact that the added time do the SPIFY2 work seems to add enough delay such that the heartrate monitor values don't get updated at the central (or at best get updated randomly every 10 to 100 seconds). Question is does the blocking of the SPI transfer cause a problem with the stack sending the updated heartrate value? (i.e. if there is a time slot that the Stack needs the updated value and if it is missed then it does not get sent (send over the radio)?). How do I get around this?

I'm trying to work with the peripheral uart and I am having trouble compiling code when I added the initialization code as specified by the How to use the WICED Smart Hardware Devices. I've attached a snippet of the code:

static void peripheral_uart_init()

{

  puart_init();

  puart_flowoff();

  /* BEGIN - puart interrupt

  The following lines enable interrupt when one (or more) bytes

  are received over the peripheral uart interface. This is optional.

  In the absense of this, the app is expected to poll the peripheral

  uart to pull out received bytes.

  */

  // clear interrupt

  P_UART_INT_CLEAR(P_UART_ISR_RX_AFF_MASK);

  // set watermark to 1 byte - will interrupt on every byte received.

  P_UART_WATER_MARK_RX_LEVEL (1);

  // enable UART interrupt in the Main Interrupt Controller and RX Almost Full in the UART

  // Interrupt Controller

  P_UART_INT_ENABLE |= P_UART_ISR_RX_AFF_MASK;

  // Set callback function to app callback function.

  puart_bleRxCb = application_puart_interrupt_callback;

  // Enable the CPU level interrupt

  puart_enableInterrupt();

  /* END - puart interrupt */

  // print a string message assuming that the device connected

  // to the peripheral uart can handle this string

}

I'm getting a compile error in the saying:

../../Apps/RAM/table_proximity/table_proximity.c:396:2: error: lvalue required as left operand of assignment

makefile:270: recipe for target '../../build/table_proximity-BCM920732TAG_Q32-rom-ram-Wiced-release/table_proximity.o' failed

I have included uart.h at the top of the file.

Any help will be appreciated.
