PSoC™ 4 Forum Discussions

Hello,

I am designing a touchpad that is 150mm x 30mm, with sensor electrodes organized in a 6x30 diamond pattern. I've selected the PSoC 4100S Plus device for use here. The next step is creating a schematic & PCB Layout.

I'm new to PCB design and all, but I've been learning how to use Autodesk's Eagle. I have not been able to find a library containing the PSoC 4100S Plus device to use. I am not sure if there's a reason for this that's over my head or if simply there's not one available? I have also located the PSoC 4100S Plus component as a library for Allegro & Altium here https://www.cypress.com/cad-resources/psoc-4-cad-libraries.

Should I be looking at making my own library component for the PSoC 4100s Plus in Eagle, or be using another program? Am I missing something big here? (Again, I'm new to this)

Hello!

On peripheral device side I'm trying to acquire the address of the connected central device when it gets connected.

Central device MAC is actually 00A050DC77C7, but when the connection is established I get an event like:

@E,0035,C,C=04,A=804929199580,T=00,I=0006,L=0000,O=0064,B=00

I tried with multiple different modules as central devices and all of them give me the address 804929199580.

I'm using a simple configuration on the central side:

.CYSPPSP,E=2,R=11223344,L=11223344,M=FFFFFFFF,G=1,S=0

SAP,L=0

SSP,F=0

/SCFG

/RBT

and on the peripheral side:

.CYSPPSP,E=2,R=11223344,L=11223344,M=FFFFFFFF,G=0,S=0

SAP,L=0

SSP,F=0

/SCFG

/RBT

On the central device I tried running GBA command, but it always returns actual MAC address:

@R,0018,GBA,0000,A=00A050DC77C7

I noticed the occurrence of this address in some other topics (e.g https://community.cypress.com/thread/45727?start=0&tstart=0), but haven't figured out what it actually means.

How should I reorganise the program to get the actual connected device's mac address?

I am using CY8C4025AZI-S413 micro controller with PSoC 4.3 creator

I have configured 4 buttons and one proximity in single cap sense block in top design

I wrote code for the same but it is not executing

If i configured single button and write the same code, it is executing

But I want to turn on seperate 4 LED if any of the buttons 1,2,3,4 pressed and and release respective led if button is released along with key number to be displayed on UART

Please Refer my code:

/**********************************************************************************************************/

int main(void)

{

    CyGlobalIntEnable; /* Enable global interrupts. */

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

    pwm_Start();

    capsense1_Start();

    capsense1_InitializeAllBaselines();

    capsense1_ScanAllWidgets();

    led17_Write(0);

    for(;;)

    {

        /* Place your application code here. */

        if(!CapSense_IsBusy())

        {

             CapSense_ProcessAllWidgets();

              if (CapSense_IsAnyWidgetActive())

            {

                LED_1_Write(1);

            }

            else

            {

                LED_1_Write(0);

            }

        }

        CapSense_UpdateAllBaselines();

         CapSense_ScanAllWidgets();

    }

}

/**********************************************************************************************************/

I should check button and proximity if buttons are enable, proximity should be disabled and vice versa

What should I do?

I am using the PWM v3 30, in a PSOC 4M series board.

I have set up two compare values in the structure along with the interrupt on pwm1 and pwm2.

I have created the ISR:

CY_ISR(pwm_isr_ON_OFF)

{

    status = PWM_ReadStatusRegister() ;

     // Pseudo code

     if (stats & COMPARE_FLAG_1)

          do_stuff(pwm1);

     else if(status & COMPARE_FLAG_2)

          do_stuff(pwm2);

    pwm_on_off_flag = 1;

}

I was hoping to identify the source of the interrupt; compare1 or compare2.  I have checked the documentation and tried looking for examples but have not been successful so far.

Help would be appreciated,

Thanks,

Hello, we are using the CY8C4014FNI-421 in a project and are seeing a problem with the I2C communication when the CY8C4014FNI-421 is not supplied. We are using P1.2 (B1) for SCL and P1.3 (A1) for SDA.  VDD and VDDIO are connected to 1.8V. As soon as the 1.8V supply is disconnected from the CY8C4014FNI-421 the SDA line is pulled to ~1V by the CY8C4014FNI-421 and this does prevent any further I2C communication on the bus. Is this a known issue and is there a way to fix it?

Thanks,

Stephan

I am using CY8C4025AZI-S413 with PSoC4 and PSoC 4000S series microcontroller.

I have chosen SCB mode as UART , enabled receive interrupt in ISR routine

       flag = 1;

        UART_SpiUartWriteTxData(gb_char);

    }

Output:

All,

How can I enable/disable an input pin in software? I am using a scb configured as a UART component with the TX pin connected through a 1K resistor to the RX pin and then connected to a bidirectional one wire device. The problem I have is I want to disable the RX pin while transmitting data. How can I do this in software? The device I am using is CY8C4025LQI-S411. Any help would be greatly appreciated!!!

Thanks,

Eric

Hi everyone,

Can anyone tell me the difference between the different properties of a feature or a page where they explain it?

Thank you

We would like to use Random static address and tried to use below code:

                char_t buffer[DEVICE_ADV_NAME] = {0};

                CYBLE_GAP_BD_ADDR_T localAddr;

                // Generate a random static address

                CyBle_GapGenerateDeviceAddress(&localAddr, CYBLE_GAP_RANDOM_STATIC_ADDR, NULL);

                // Set the device address

                CyBle_SetDeviceAddress(&localAddr);

                CyBle_GapSetIdAddress(&localAddr);

                // Change the address type in the discovery parameters

                cyBle_discoveryParam.ownAddrType = CYBLE_GAP_ADDR_TYPE_RANDOM;

We now see that the address change from the public static address to random static address but when we try it on two different devices we get the

same address C0:49:29:19:95:80

is the BLE random generator not random? is done init of the BLE random generator needed with a seed to generate pseudo random addresses?

We use BLE 4100 chipset. tested with BLE 3.10 and 3.54 components.
