Hi all

Our FPGA may send variable length data(4B~16kB, integral multiple of 4Bytes) to FX3 in which firmware runs as slave FIFO mode, host app invoke XferData() to initiate a BULKIN transfer for reading data stored in FX3.

At each BULKIN event initiated by host, a certain len parameter must be passed into XferData() refer to Cypress CyAPI Programmer's Reference, for example 16384, if actual length of packet which sent by FX3 is shorter than 16384(ie partial packet), will XferData() receive the short length packet and return ture or return false for time-out? if this function can receive short packet, where can i get the actual length after the XferData() executed ?

Is it possible to change the RSSI of bluetooth?

I think it is possible to get it with "wiced_bt_dev_read_rssi()", but I couldn't find the function to set it.

Hello,

I'm working to a Project that has an USB connection configured as Self Powered.

I'll use CY8CKIT-149 to make a first Prototype.

In order to implement Self powered configuration, R7 and D1 will be removed.

Kitprog will be fed throug J6, PSoc and BLE module will be fed through J1 / J2.

My question is:

What happens if I switch off supply to CY8CKIT-149 while USB Cable remains connected to host?

Should I expect damages to Kitprog  USB Interface?

Thanks,

Alfonso

Hey, 

I am new to development on the PSoC platform and I am attempting to configure UART on this device. It is a PSOC5LP - 050 board. I'm unable to configure the COM port I am supposed to read it on, because it does not show anything on device manager about which virtual COM port I should connect. 

I am able to program other components and I have already worked on a few applications which are working fine. Sending a screenshot of my device manager. On PSOC programmer also, the Upgrade firmware option is 'greyed-out'. Any advice is appreciated. 

EDIT: I have checked the example documentation and connected the RS-232 with the related Pinouts to the Rx and Tx pin and still nothing appears on my COM port. 

Hi all

For infineon+CYPRESS people.

Are there any plan for releasing PSOC 4200L prototyping kits.

I vote for it😊

We are using CY_BLE_EVT_GAP_DEVICE_DISCONNECTED to know if the peripheral got disconnected. On CY_BLE_EVT_GAP_DEVICE_DISCONNECTED we perform connection cleanup, but we noticed on one time the peripheral disconnected but it seems like we missed or didn't get CY_BLE_EVT_GAP_DEVICE_DISCONNECTED.

Is it expected not to get CY_BLE_EVT_GAP_DEVICE_DISCONNECTED event when device disconnect? Is there way to manually check if BLE stack properly disconnected?

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?

I have an Psoc63 as BLE 5 central and three PSoC 4200 as BLE 4.2 peripheral. After a successful discovery from central using whitelist I try to connect to one of the three peripheral using his address.  Unexpectedly the central was connected with a peripheral with different address!!!!! Also I try an unexisting address and again it was connected with a random peripheral with different address. Maybe the issue arise from the BLE 4.2 peripherals.

I will appreciate your help to this

Hello, I am currently developing a USB PD power bank that utilizes bi-directional 60W input and 100W output. My plan is to use SC8815 I2C bidirectional buck-boost controller for Power and CYPD 3171 as the PD controller. I want to use CYPD3171 to control SC8815 over I2C to configure SC8815 modes(input and output) as well as output and charging voltage, etc. I also want CYPD3175 to inform the main MCU of PD modes, voltages, currents etc. My question is that what is the best way to achieve this functionality? Should I use EZ-PD config utility or PSOC programmer to write the code? Also, how should I upload the program onto CYPD3175, can I use an ST-Link, or use another MCU over I2C? Can someone recommend me a software and programmer combo? I saw this reference design using sc8915 which is extremely similar to my application, and I think I am going to reference the schematic, but I don't see where the code is located, could someone also inform me of where it is located so I can use it as a reference if possible? I am new to the CCG3 ecosystem, thank you very much!
