Hi Team

I am using Cypress PSoC 4200 for CY8C4248LQI-BL483 for my project. I see that for some reason, the PSoC is not generating the following #defines

#if (CY_SFLASH_XTRA_ROWS)

    #define CY_SFLASH_USERBASE  (CYREG_SFLASH_MACRO_0_FREE_SFLASH0) /**< The base pointer of the user SFlash memory. */

    #define CY_SFLASH_SIZE      (CYDEV_SFLASH_SIZE)                 /**< The size of the SFlash memory. */

    #define CY_SFLASH_SIZEOF_USERROW        (CYDEV_FLS_ROW_SIZE)    /**< The size of the SFlash row. */

    #define CY_SFLASH_NUMBER_USERROWS       (4u)                    /**< The number of SFlash row. */

#endif /* (CY_SFLASH_XTRA_ROWS) */

How do I generate it? Is there a setting which needs to be enabled in the PSoC creator ?

I have my cyble-022001 based sensor working fine and need to make an app to write the data to file on android or IOS device. I have already made a simple app that shows the data on screen. I used Evothings Studio and the app so far runs only in Evothings viewer app, thus it's not a compiled native app, just HTML and javascripts, but should be possible to compile using cordova + native SDK.

I'm new to apps and quite confused what is needed for an app the be able to communicate via BLE and write data to a file for hours while the phone is locked or used for something else.

Does it need a service? Foreground or background service?

What is a good platform to make such on app for both android and IOS. Evothings + cordova seems easy to get started with, but I don't know if they have all the functions needed, especially related to keeping the data logging on while the device is locked. Also Evothings has not been updated since 2017.

I'm good at c, know some c++ and javascript. I have not used java nor swift, which seem to be the languages native SDK's use. I did make a simple app with android SDK a few years ago. I guess that was java?

Hi,

I'm using a CYBLE-212006 module in combination with PSoC Creator 4.2.

I try to connect to a ble peripheral as shown in Day011_Central_Observer project from 100 Projects in 100 Days.

1. I scan for peripherals
2. Everytime I found one, I store this peripheral in an array
3. After stopping the scan I try to connect to the selected peripheral.
4. When I call apiResult = CyBle_GapcConnectDevice(&connectPeriphDevice[Periph_Selected]); the Api result is CYBLE_ERROR_INVALID_PARAMETER

What does this error mean and how to fix?

Here a a code snipped:

CYBLE_GAP_BD_ADDR_T     connectPeriphDevice[10];

/*

* Function Name: Get_Adv_Scan_Packets

*/

void Get_Adv_Scan_Packets(CYBLE_GAPC_ADV_REPORT_T* scanReport){

uint8 RepIndex; //Index for Bytes in Scan Response Packet {

        if (devIndex < 9) {

             IsDetected = 1;

            // Receiving Advertisement Packet

            if ((scanReport->eventType == CYBLE_GAPC_CONN_UNDIRECTED_ADV)||

                (scanReport->eventType == CYBLE_GAPC_CONN_DIRECTED_ADV)||

                (scanReport->eventType == CYBLE_GAPC_SCAN_UNDIRECTED_ADV)||

                (scanReport->eventType == CYBLE_GAPC_NON_CONN_UNDIRECTED_ADV)){

                memcpy(connectPeriphDevice[devIndex].bdAddr, scanReport->peerBdAddr,

                sizeof(connectPeriphDevice[devIndex].bdAddr));

                devIndex++;

            }

        }

        else {

            printf ("Device Counts Exceeds 10 \r\n");

        }

    }

}

//This function is called in main.c

void Handle_ble_Central_Observer_State(void) {

     if (CYBLE_STACK_STATE_BUSY == CyBle_GattGetBusStatus()){

          /*If stack is busy wait for ready signal*/

          return;

     }

     if (!IsConnected) {

          if(CYBLE_STATE_DISCONNECTED == CyBle_GetState()) {

              if(IsSelected) {

                    apiResult = CyBle_GapcConnectDevice(&connectPeriphDevice[Periph_Selected]);     //ERROR

                    if(CYBLE_ERROR_OK != apiResult ){

                         printf ("Connection Request to peripheral failed \r\n");

                    }

                IsSelected = 0;

             }

          }

     }

}

Thanks!

Goodmorning,

i have a board with Psoc 4 (CY8C4247AZI-M485) and i need to use can bus with 125Kb as baud rate, i have some difficult to find right clock configuration.

I know should be better to have an external OSC but... i don't have it, some suggestions?

thanks in advance

In my project, I have clocked the MAX11201 ADC via CYBLE-012011-00 I/O pin, but without using the CPU, is there any way to do that, i tried the PWM but dont know why i am  not getting the pwm signal at the output pin (port 3 pin 7).

Hi：

     How should I know the meaning of each bit representative about  the parameter status of  CSD data structures of CapSense_RAM_STRUCT?

Discovered this when I tried to change the code, and the original echo function still worked in PuTTY.  Verified that the code was not running by inserting an LED indication in the clause where the received byte is verified to be non-zero, and is written back out.  The LED never comes on even though the echo function works.
