how to configure SPIM_SCBCLK  to 24MHZ?

can someone explain that on what parameter it depends on?

i have research documents from Cypress, i didn't find a proper flow of solution.

Thanks,

Hello.

I have selected module CYBLE-222014-01 (based on PSoC4 BLE) to develop a new project where this module must work simultaneously both as CENTRAL (handling other module working as peripheral) as PERIPHERAL (getting/setting characteristics from/to a smartphone).

I have started to test this situation (using 2 modules CYBLE-222014-01 and a smartphone). First I set the Central&Peripheral module as Peripheral (using function CyBle_GappStartAdvertisement()). Then I try to connect to the second Peripheral Module (using function CyBle_GapcConnectDevice()), but I receive an error event CYBLE_EVT_HCI_STATUS with parameter CYBLE_HCI_MAX_NUMBER_OF_CONNECTIONS_ERROR.

My questions:

     Is it posible use module CYBLE-222014-01 working simultaneously both as CENTRAL as PERIPHERAL?

     If not posible, Is there any other module that suport this working mode?

Thanks in advance.

Using PSoC 4200 BLE.  I Would like to store a few bytes in SFLASH and read them.  I'm using the Cypress provided function CySysSFlashWriteUserRow(.., ...) function to write to SFLASH.  However it's unclear how to read from SFLASH.  I believe I would access the memory directly by reading the contents at the SFLASH user defined row address.  I'm struggling to find the SFLASH address for the user defined rows.  Any help &/or code example is appreciated.  An example for reading from SFLASH would be most beneficial as I'm able to write just fine to SFLASH. 

Thanks,

hi everyone

i have a one sensor that produces square wave.I want the counter to count on the positive edge of the square wave but i didnt start counter.i use cykit 049 4200.

I will be glad if you help me.I would like a sample project if possible.

Hello,

I'm Having some problems with the Notification functions on BLE.

My project is a BLE Client that is trying to subscribe to some notification characteristics of a Server.

If I'm following the examples right the way to enable notifications on a characteristic is:

void Send_EMG_Subscribe(CYBLE_CONN_HANDLE_T connHandle,uint16 EMG_attrCCDhandle)
{
    CYBLE_API_RESULT_T apiResult;
    CYBLE_GATTC_WRITE_REQ_T ReqParam;
    uint8 value = 0x0001;
    ReqParam.attrHandle = EMG_attrCCDhandle;
    ReqParam.value.val = &value;
    ReqParam.value.len = 1;
    enableNotificationReqParam.attrHandle = EMG_attrCCDhandle;   
    apiResult = CyBle_GattcWriteCharacteristicDescriptors(connHandle,&ReqParam);  
    BLE_Error_Handler(apiResult);
}

After calling this function i receive a event CYBLE_EVT_GATTC_WRITE_RSP. This should indicate that the subscription was successful.

But i don't start receiving new events with information lime CYBLE_EVT_GATTC_HANDLE_VALUE_NTF.

What am i doing wrong?

Thanks!

Can the /HI pin use a 1.8V pullup while the CY8CMBR3106 is supplied from 3.3V?

I need to power the 3106 from 3.3V, and I have 3.3V-referenced I2C. But the controller that will receive the hardware interrupt is a 1.8V device. The datasheet ("Host Interrupt" section) describes the host interrupt pin as open drain. But the very next bullet describes the VDDIO supply on the 3108 and how it enables comm at lower voltage levels.

So the datasheet is not perfectly clear. Is the '3106 host interrupt a true open drain that can be referenced to voltage levels lower than VDD?

Thanks

What is the internal operating frequency or range of frequencies of the CY8CMBR3106?

Thank you

Hi,

I was following the Android_BLEApp_Demo_09.mp4 to determine the pins used for the H bridge.  The video uses a dual h bridge. I use a single h bridge by the same manufacturer.

There are 6 pins that connect from the kit to the H bridge.  I don't video covers all pins?  I see 4 pins covered GND, power, direction, and M (PWM output)? Could the other 2 pins be for the quadrature?

thanks,
Joseph

Hello,
I am testing the CE210291_CapSense_P4_One_Button example using a CY8CKIT-145-40XX PSoC® 4000S CapSense Prototyping Kit.

I have changed the example I2C pins to P1[0] and P1[1] for compatibility and cap sensing on P1[5] after removing the R47 touch button series resistance.

CapSense scan is configured at 8bit, 3000KHz sense clock frequency

System->Debug Select->GPIO is selected to disable the debugger.

I measured the current consumption on J3 after removing R22 0-ohm resistor, in Slow scan mode is 270uA and in fast scan mode is 280uA while expecting less than 6uA consumption in slow scan mode.

Is there some peripheral to be disable or some HW component to be removed from the evaluation board?
Thank you,
