PSoC™ 4 Forum Discussions

I am making a program using PSoC 4 BLE software that connects to the CySmart App. I want to control two different LEDs (red and green) using PWMs so that one LED would blink at the speed of one second, and another would blink at 2 seconds. I have tried doing this, but this error occurs: Pin guidance unavailable: Resource limit: Maximum number of Datapath Cells exceeded (max=4, needed=6).

Does anyone know how to fix or get around this problem?

Thanks,

I created a simple UART bootloader and bootloadable. Both so far use just GPIO pins to control LEDs, and a standard UART component. Everything is configured as in AN68272. When trying to load the bootloadable with Bootloader_Host_GUI_exe, I'm getting error 0x0000A - "The flash row is not valid" (per Bootloader_Host_GUI_exe source). The workspace is attached. I'm using PSOC Creator 4.1 update 1 with CY8CKIT-041-40XX. Any help or pointers will be appreciated.

I am working on a capsense design and someone informed me that they used a capsense device that did not require programming (CY8CMBR3102). Would this work in that fashion? In other words is it pre-programmed with anything where i can just place it into my design and have it work / register inputs?

As stated in this discussion, in the specification of PSOC 4, it stated:

"UART Mode: This is a full-feature UART operating at up to 1 Mbps. It supports automotive single-wire interface (LIN), infrared interface (IrDA), and SmartCard (ISO7816) protocols...."

However the Creator does not have LIN bus component, I would like to ask if there is any example or library that implement the LIN bus in PSOC4 ?

I am actually using PSOC 4 BLE.

Thank you.

Hi,

I know how to set the custom characteristics of a custom service using following code -

CYBLE_GATT_HANDLE_VALUE_PAIR_T tempHandle;
tempHandle.attrHandle = CYBLE_CUSTOMSERVICE_NAME_CHAR_HANDLE;
tempHandle.value.val = data;
tempHandle.value.len = sizeof(data);

CyBle_GattsWriteAttributeValue(&tempHandle, 0, &CYBLE_CUSTOMSERVICE_NAME_CHAR_HANDLE, CYBLE_GATT_DB_LOCALLY_INITIATED);

But now I want to set characteristics of Device Information service programatically (i.e Serial Number String). These services are standard services. Is there any example which I can use to set standard characteristics? If I try the above code to set it, it doesn't work. I can see the constant value set using the BLE settings.

Please help. Thanks in advance.

Kind Regards,

Jitender

How do I get to this event CYBLE_BLESS_STATE_EVENT_CLOSE ?

I need to use it for CyBle_GapUpdateAdvData( ) function.

What will force that event?

Is it

CySysPmSleep(); ?

CySysPmDeepSleep(); ?

CySysPmHibernate();?

I will make this for the Peripheral.

Also if it hibernates, sleep, deep sleep ... will i ever connect to it ? via Central.

Hi, I'm using a '042-BLE' kit here and it's working fine. But I can't get a timer interrupt to work. Here is the main code:

 * ========================================
*/
#include <project.h>

 
uint16 ms_count = 0;
 
CY_ISR(MY_ISR)
    {
    ms_count++;
     
    if(ms_count == 1000)
        {               // 1 second
        LED_2_Write(!LED_2_Read()); // Toggle LED
        ms_count = 0; // reset ms counter
        }
    }
 
int main()
{
    Timer_Start(); // Configure and enable timer
    Timer_ISR_StartEx(MY_ISR); // Point to MY_ISR to carry out the interrupt sub-routine
    CyGlobalIntEnable; // Enable global interrupts
     
    for(;;)
    {
        // Infinite loop for timer/interrupt to keep executing
    }
}

The pin output is square running at 900us, not 1 second I had hoped for. Changing the clock frequency makes no difference.

This is going to be such a silly problem, I'm already embarrassed, but I've at this for some time and I can't see what is wrong.

Project is  attached.

How can I change an advertisement packet...

I followed this tutorial...

PSoC-4-BLE/100_Projects_in_100_Days/Day009_Dynamic_Broadcaster at master · cypresssemiconductorco/PSoC-4-BLE · GitHub

and made my own version for my application.. I'm currently debugging it.

I set my Service Data to 0.

I need it to switch it from 0 to 1, and vice versa.

CYBLE_GAPP_DISC_MODE_INFO_T discoveryReport;

int main(void)

{

    CYBLE_API_RESULT_T apiResult;

    CyGlobalIntEnable; /* Enable global interrupts. */

    apiResult = CyBle_Start(StackEventHandler);

    /* Place your initialization/startup code here (e.g. MyInst_Start()) */

    for(;;)

    {

        CyBle_ProcessEvents();

        DynamicADVPayloadUpdate();

    }

}

void DynamicADVPayloadUpdate(void)

{

    if(CyBle_GetBleSsState() == CYBLE_BLESS_STATE_EVENT_CLOSE)

    {

        discoveryReport.advData->advData[14u] = 0x01;

        CyBle_GapUpdateAdvData(discoveryReport.advData, discoveryReport.scanRspData);

    }

}

void StackEventHandler(uint32 event, void *eventParam)

{

    switch(event)

    {

        /* Mandatory events to be handled by Find Me Target design */

        case CYBLE_EVT_STACK_ON:

        case CYBLE_EVT_GAP_DEVICE_DISCONNECTED:

            /* Start BLE advertisement for 30 seconds and update link

             * status on LEDs */

            CyBle_GappStartAdvertisement(CYBLE_ADVERTISING_FAST);

          break;

        case CYBLE_EVT_GAPP_ADVERTISEMENT_START_STOP:

            if(CyBle_GetState() == CYBLE_STATE_DISCONNECTED)

            {

                CyBle_GappStartAdvertisement(CYBLE_ADVERTISING_FAST);

            }

            break;

        default:

        break;

    }

}
