Hi All,

I am creating a new design variant of a working project targeted for the 222014-01 BLE module by copying a working project that was targeted for the 222005 module, changing its name and using Device Selector to choose the new module type.

After doing this, I get three errors during the fitting stage:

To make matters worse, I've seen this error before but I cannot remember how I fixed it.  I have tried updating the components (BLE was updated to 3.66 and cy_boot to 5.90), but this hasn't eliminated the errors.

The error message suggests how to fix the problem but I can't find where one sets the "User provided" option.

Thanks,

Scott

Hello,

I am trying to include the 'CyAPI.lib' from the x64 Cypress library folder and trying to build in C++ 10.4 Builder for the multi target platform. But, I am facing problem with a linker error like "[ilink64 Error] Error: Unresolved external 'CCyUSBDevice::CCyUSBDevice(void*, _GUID, int)..................'  while trying to build. Please find the attached snapshot for more details. 

Any guidance on the matter would be greatly appreciated !!

hello,

i've succesfully tried and reproduced the example called "qspi_read_write_using_sfdp".

When i'm importing the rights function in my project, the init function fails (cy_serial_flash_qspi_init).

When i'm digging into the details, it fails when calling Cy_SMIF_MemInit which return CY_SMIF_SFDP_SS0_FAILED

i've compared everything, and i'm not able to find what i'm doing wrong.

is there anybody who experienced the same issue ? thanks

Traveo II CYT4B can run on 350MHZ?      code is as follow:

#if (CY_SYS_PLL400M_0_FREQ == CY_SYS_PLL400M_0_350MHz)
// PLL_OUT = 24,000,000(Feco) / 3 * 125 / 5 = 200,000,000Hz
// Restriction: 400,000,000 <= Fvco <= 800,000,000
// This time, Fvco = 16,000,000 * 175 / 4 = 700,000,000.

#define CY_SYSTEM_PLL0_CONFIG_REFDIV (2UL)
#define CY_SYSTEM_PLL0_CONFIG_FEEDBACKDIV (175UL)
#define CY_SYSTEM_PLL0_CONFIG_OUTDIV (6UL)

/*
#define CY_SYSTEM_PLL0_CONFIG_REFDIV (3UL)
#define CY_SYSTEM_PLL0_CONFIG_FEEDBACKDIV (125UL)
#define CY_SYSTEM_PLL0_CONFIG_OUTDIV (5UL)
*/
#elif (CY_SYS_PLL400M_0_FREQ == CY_SYS_PLL400M_0_320MHz)

Dear Sirs and Madams,

The item "Table 3. External Clock Input Requirements" is defined in AN72332, where "Rise time / fall time 3 [ns] (Max)" is specified. 

Please tell us this voltage condition. (For example, 20% -80% VCC, not specified, etc.)

Regards,

I'm trying to send data packets between two BLE devices (A and B) with both peripheral/central GAP roles.  When I add and remove other devices to the BLE network, I find by debugging device A that it can enter a state where any attempt at sending a GATT notification to device B returns a  CY_BLE_ERROR_INVALID_OPERATION error, though it can send GATT notifications to other devices that are connected.  In this circumstance, A is peripheral wrt to device B, and GATT write requests can be sent from device B to device A.  Cypress code comments indicate CY_BLE_ERROR_INVALID_OPERATION occurs when the BLE stack queue is full or some other problem occurs.  Is it possible to look at the BLE stack queue in debug mode to get a clearer idea of what's going wrong?

Hello,

I am designing a product for medical liquid sensing and I am a bit lost in all your products.

My tank is about 20cm high, and I need a 1mm accuracy (so 200 divisions). My sensor PCB can be up to 3cm wide (so 20cm x 3cm for sensor).

The distance between the liquid and the PCB is 2.5mm PVC, 0.5-1mm air, and 1.5mm ABS.

I was wondering if you had recommendation on which product to use, and how many (segmentation of the sensors). I already have a microprocessor in my product and only need the sensing part (via like I2C).

I am testing CX3 for our new product.

Sensor has 4 lane MIPI with 600Mbps. (Is it right that the maximum summing speed of CX3's MIPI is 2.4Gbps)

The maximum speed of our sensor is 120 frame per second at 1920x1200. 

But I found below in "CX3's Technical Manual".

These means that we can't edit GPIF , so our system can't have high frame rate over 30 fps at 1920x1080

Is it right?

The system which I want to make is below.

Is it possible? 

Or if you have another solution for high speed camera with CX3, let me know it.

Thank you

Best regards

Hello Everyone,

I was hoping to create an airpods like headset using 2 eval boards (CYW920721B2EVK-02).  

I see the bluetooth headset example projects, but these seem  be just for 1 single device/headset.  Has anyone had success using 2 devices, acting as a headset when connected to a phone, similar to the functionality of all the wireless earbuds on the market today?
