Cx3 has a camera, and other devices can preview images by UVC connection . The customer want to add the time stamp on the image.Can cx3 realize this function?Or is there a corresponding interface?
Show LessI am following "Snippet 2: PDM/PCM Asynchronous Receive" from the link below:
https://cypresssemiconductorco.github.io/psoc6hal/html/group__group__hal__pdmpcm.html
The pdm_pcm_event_handler never gets called but when I comment out the line below it starts working.
Hello Infineon Experts,
We use a CX3 and one or two related image sensors on our board, and we are facing a CY_U3P_ERROR_FAILURE value returned by the CyU3PMipicsiSetSensorControl() API. This behavior is random, but the error rate is over 20 %.
We probed the I2C bus and some other significant signals (CX3_RESET*, CX3_XRESET and CX3_XSHUTDOWN), to look what’s happen (see attached pictures):
Do you have an explanation for this error CY_U3P_ERROR_FAILURE?
For your information, both SDA and SCL signals are pulled high with 2kΩ resistors, and the I2C block is initialized (by calling CyU3PMipicsiInitializeI2c() API) before initializing the MIPI-CSI-2 block (i.e. before calling CyU3PMipicsiInit() API).
Best Regards,
Eric.
Show LessHi,
将USB CDC code example工程修改,将工程下载到自定义的使用CY8C624AAZI-S2D44芯片的板子中,将usb连接到电脑端,可以识别到一个设备:CDC Code Example,但是显示没有安装驱动,从例程文件目录下的win_drv安装驱动,提示安装驱动时出现错误,请问这种情况应如何处理?需要如何才能获得正确的驱动文件?工程请参考附件。

Hyperflash is not responding to any commands except status register read. I tried word programming , buffer programming, sector erase, Chip erase, DeviceID reading but none of this worked. Everytime status register value remains 0x80.
Can someone tell me what could be the issue.?

Hello!
My team and I are working on a project that involves a portable, handheld device and a custom made docking station for that device. The portable itself will contain hardware that will generate a 2-lane DisplayPort video signal that we would like to output over USB-C to our docking station that will then convert the video to HDMI before going to a normal monitor/TV.
My question is whether or not the example "CCG2 Type-C to DisplayPort" reference design is a good design to follow. It seems as though that design is taking a USB-C input, handling the Alt Mode and Billboard handshaking, and then outputting a DisplayPort signal. We want the opposite - a solution acts as a DisplayPort source to be transmitted over USB-C. Does Cypress have a solution like this that exists?
Our portable also has a LiPo battery that needs to be charged from this USB-C cable such that the portable is a DisplayPort source but a power sink. There aren't any cases where our portable would act as a power source that would supply power across the USB-C cable. I was hoping to use TI's TPS25750 to handle this USB PD negotiation, but I don't think that will work well with this DisplayPort Alt Mode ecosystem. Will the Cypress CYPD2119-24LQXIT be able to handle these PD negotations on top of handling the DisplayPort Alt Mode?
Please let me know if this doesn't make sense and I can absolutely provide more information.

Show LessDear 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.)

Show LessI am confused by the classification of CYBLE-416045 and EZ-Serial Support. Older posts (2019) claim there is no intention for CYBLE-416045 to support EZ-Serial and I do not see this among listed devices in documentation claiming such support, yet the CYBLE-416045-EVAL I purchased is listed as an EZ-BLE and documentation which comes with the kit references EZ-Serial. Can you please clarify the standing of this module. If there is no intention to make this module support EZ-Serial, what is the closest module to it that does (eg, Bluetooth 5 support, number GPIOs, etc.)
Show LessI 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!

Hi everyone,
I want to configure the DS-1 port of CY611 EZ-USB HX3PD EVK to supply 12V. But when I try to configure using EZ-USB HX3PD configuration Utility - PD Controller- Port 1, it shows me error - Atleast one 5V PDO should be enabled in Source PDO. But if add another source PDO of 5V, it does not save the configuration.
Can anyone help please ?
Thanks
