Hello, 

I have connect the debug board to my notebook (Win 10) and install all the software from the website. However, the blue LED on the debug board doesn't blink and  Cypress Ble-Beacon shows no device is connected. (I have check the serial port is corrected). Besides, my cell phone (Pixel 3 XL) also shows no device is connected . The indoor light brightness is about 300~500 lux (white LED). How can I do to solve this problem?

Hello.

I have a question about the CY3672-USB.

The target device is CY22381.

Please refer to below.

1. Does CY3672 support both Windows 7 64-bit and Windows 10 64-bit ?

2. I need additional programmers for CY22381. Should I use the CY3675?

    In this case, does CY3675 support both Windows 7 64-bit & Windows 10 64-bit ? 

Thanks and Regards,
YS

I need to achieve low standby power consumption in a system with an FX3 and a Xilinx FPGA.  This system primarily remains in a low power idle state for 99% of the time where neither the FX3 or FPGA is being used. 

Referring to the block diagram below, the PSoC is powered continuously through the LDO.  The PSoC controls switching regulators that power a USB host, the FX3 and the Xilinx.  The PSoC also performs aggressive power management to maximize battery life.

The PSoC turns on power to the FX3 and the Xilinx FPGA.  All of the FX3's core VDD(x) and IO VIO(x) supplies are powered.  The FPGA's IO banks connected to the FX3 are powered as well to avoid the FX3 driving an unpowered FPGA or vice versa.

Later, the PSoC will apply power to the USB Host system which in turn powers VBUS on the USB connector.  VBUS is used to hold the FX3 in RESET (using an RC network) until VBUS is stable.

Questions:

1. Will this method of powering the FX3 work? 

2.  I'm confused about the use of VBATT versus VBUS FX3 signals.    The Super Speed Explorer connects VBUS on the USB connector to the FX3's VBUS signal.  The FX3's VBAT signal is not connected on the SSE.   The FX3 DVK connects a select-able power supply(+5V,+3.3,+2.5) voltage or a battery through a diode OR to the FX3's VBAT signal.  VBUS from the USB connector is connected to the FX3's VBUS signal.    Other FX3 based boards connect the VBUS line from the USB connector to both VBAT and VBUS on the FX3.  I'm not sure what is the correct usage for my application.  Please explain.

3. I have other H/S USB devices that would share one USB Gen 3 connector.  It is possible to insert a CY7C65642 USB hub on the D+ and D- signals?

Thanks for your help!

Dear Yatheesh,

Sorry to bother you again.

After the last /RD signal problem was solved, no more underrun error.

But recently, all system combined test, I received error "No error : 18" from CY3014 uart port ,then, Xfer to FPGA failed.

Please kindly advise what is "No error : 18" ?

你好，我用Bus Hound软件（或其他工具测试遇到一样的问题）测试接收cx3 hid数据。当数据量频率不大时（数据包都是一样大小，64个字节），接收数据都正常，可以测试一天一夜。但是当发送的数据频率增大时，cx3这边很容报错：CY_U3P_USB_EVENT_EP_UNDERRUN，此错误的解释是：Indicates that a data underrun error has been detected on one of the USB endpoints. The event data will provide the endpoint number. 当高频率发送hid数据出现此错误后，即使复位hid，也无法恢复正常。复位hid如：

if (glIsHIDApplnActive)
{
CyFxUsbHidApplnStop();
}
CyFxUsbHidApplnStart();

请问如何解决cx3这种高频率发送hid报错问题？

Hello,

I have implemented an example web application based on the angular framework which I would like to host on the Laird EWB platform.
So far I´ve managed to place all web resources (roughly 1.2 MByte) on the extrnal 2MByte SPI Flash and link them to the http server via the read only filesystem.
I can access the page using a http browser but the Wi-Fi performance is questionable:
-> Accessing the main .js file (~450kByte) while the EWB is configured as client in my home network takes roughly 75 seconds. (equals 6.3 kByte per second)
-> Accessing the same file while the EWB acts as access point any my Laptop is connected to it takes even 2 minutes. (equals 4 kByte per second)

Are these numbers reasonable or is there an issure with my demo application?

I am using WICED_SECURITY_WPA2_AES_PSK and standard http (not https) server (libraries\daemons\HTTP_server) with WICED Studio 6.6. There are no other devices connected to the access point and the web browser runs on my laptop and is surely fast enough. The demo is based on /snip/http_server_sent_events example without much modifications. The make target configuration is LAIRD_EWB-FreeRTOS-LwiP-SDIO download run

Thanks,

Martin

Hi all

Here`s a strange problem, XferData() may failed when slave endpoint sent a short packet with a particular length.

we`re trying to transfer data from FPGA to PC host by FX3, FX3 runs with a slave FIFO firmware, EP2 IN(0x82) is initiated in FX3 for BULK IN transferring, in each transfer test, firstly, PC host invoke XferData() to generate a BULKIN transfer(bufLen is always set 16384, pktMode is set TRUE) and waiting for a packet from FX3, then our FPGA send a short packet to FX3, at each test,packet length is different, short packet is ended by asserted the PKT_END pin .

XferData() return TRUE in most of tests, but failed at  several test, after research of these failed tests, we found that if FPGA send packet with length of 2048,4096 or 8192, XferData() retrun FALSE and timed out happened, such a werid thing. any body can help me ?

BTW,  these two results may help you:

1.XferData() can be successful when actual length is 8191 or 8193, but if FPGA send 8192 bytes to FX3, XferData() must be failed.

2.if we set 8192 to bufLen parameter, XferData() return TRUE when FPGA send 8192 bytes to FX3.

here`s main part of BULKIN transfer code at PC host side(VS2013):

Hello.

I open "snip/sd_filesystem"

At row 49 of the file "sd_filesystem.mk" I read this line ...

"# For exFAT support, use filesystems/FileX/exFAT (for licensees only)"

Have I to buy particular licence for  exFAT ?

Hi,

Does anyone has an idea how to port the AnyCloud/Modus Toolbox for use with a cellular modem in stead of the Wifi / BT interface? Is there a PSoC6 devkit out there with a cellular modem on board? Also, we need to connect to our existing Microsoft Azure Cloud. Did someone already do this?

Any help / suggestions /... is very welcome.

Thanks,

Kris

Hi,

as stated in the newest datasheet (002-14796 Rev. *M), the CYW43438 supports Bluetooth 5.1

Does that apply to all hardware revisions? (I haven't found any information on hardware revisions). Is a new firmware/driver neccessary to support the feature and will it be available for Linux?

Cheers
