USB low-full-high speed peripherals Forum Discussions

We built a hardware packet sniffer as an add-on for the FX2LP boards that are sold on ebay, AliExpress and similar sites.

I can answer technical questions here. Other info is on www.bugblat.com/products/ezsniff/

I am currently using the c65215 on the CyUSB3Kit-003 to access the FX3, but have some questions regarding reset control:

The JTAG interface provides vendor commands for Read/Write/Enable and Disable. Does any of these affect the state of TRST#/pin 9?

Also, I would like to wire GPIO_15 (pin 10) to the RESET# line of the FX3, to be able to control reset from the C65215. This would allow better integration with OpenOCD which somewhat requires control of both SRST and TRST for reliable startup. Currently, I have to emulate a "reset halt" by keeping the Reset button pressed and entering a halt at the prompt.

AFAICS it should be possible to control the GPIO from openocd (given the right vendor requests are added to the openjtag driver).

68013配置如下：

1）EP2：OUT，512*2，作为命令端口；

2）EP4：IN，512*2，作为命令端口；

3）EP6：IN，512*4，作为数据端口；

4）同步写入方式，手动提交包。

用我们写的软件，在采集过程中拔掉USB数据线，然后插上，不能从EP6接收数据，xferdata或FinishDataXfer返回的 数据长度等于0。但EP2和EP4收发正常。FPGA这边看，EP6已满，FPGA的slwr信号不再拉低。

在此咨询各位高手，望指点一下，小弟拜谢。

Hi all,

I have used CY7C68013A-56LTXI (industrial version) as USB 2.0 controller.
I will check this controller chip for automotive.
If CY7C68013A-56LTXI could not be used for automotive,
I want to know which chip can. 

Regards, thank you.

Hi,

I had downloaded Cypress SuiteUSB but had to uninstall it. When I tried to install it again, it throws up an error (screenshot is attached). This is an important aspect of my project so please help. Thank You. 

Hi,

I'm interested in evaluating the FX2LP18 USB controller in an upcoming low-power embedded design and I would like to purchase the CY3687 Developers Kit.  However, according to the Cypress Website (http://www.cypress.com/documentation/development-kitsboards/cy3687-mobl-usb-fx2lp18-development-kit) this kit is out of stock and the only distributor that seems to carry this development kit (Avnet) also does not have it in stock.

Is the CY3687 Development Kit still available for purchase?  If so, what is the current lead-time for this kit and where can it be purchased?

Is the MoBL-USB FX2LP18 controller still supported and recommended for new dessigns or would the FX2LP be a better choice for a low-power embedded design since the development kits for this part (CY3684) appears to be widely available from multiple distributors and directly from Cypress?  Since this is a low-power design I would prefer the FX2LP18 since the core operates at 1.8 V vs. 3.3 V for the FX2LP.

As another possible alternative, since the new design will only be connecting to a USB 2.0 host, is it possible that the FX3 would consume less power than the FX2LP / FX2LP18 when connected to a USB 2.0 host?

Any feedback would be appreciated.  I look forward to your response.

Hi all,

Apologies if I've selected the wrong forum; it wasn't clear to me where questions regarding CCGx USB-C devices should go. I am attempting to build a proof of concept for a simple DisplayPort pass-through using the CYPD3120 DP Dongle example firmware. So far all I have is a blinking LED and billboard info showing the vendor/product ID. I am also able to read the configuration using EZ-PD Configuration Utility.

What exactly is needed to prompt a HPD event? My understanding in reviewing the example is that this is done using events transmitted on the CC line. But I see nothing that calls eval_app_alt_hw_cmd, which appears to be the driver for the generation of the HPD events. Is there any way to prompt the HPD event/message programmatically?

I also have a DDI (an I2C slave device ready to provide an EDID on the correct address) connected to the AUX_P/AUX_N lines on the CYPD3120, but I have not been able to get the Mac to interpret the dongle as a display.

Has anyone been able to successfully prototype using the CYPD3120? Any pointers?

Thanks!

Hello,

Does anybody experienced the use of NX2LP-Flex with Android ? We plan to use it in our board, and since this seems not to be a problem with Windows, it should works flawessly with Android, given the final device can handle USB host.

But i can't find any experience feedback about it. We plan to create an UMS based-driver with custom features (including I2C, GPIOs), first for Windows, then for Android. 

As actually i'm not exactly seeing the constraints of the NX2LP-flex, i want to be sure we don't need ie a vendor DLL or anything that would make it not working.

Thank you

Hi, 

Hi,

I am using Windows 7 x64 operating system and cy7c80 controller device with FPGA.So far I have been able to successfully adapt Streamer example and use bulk endpoint.

The problem I am facing at the moment is that I am unable to perform control endpoint transfers using CyAPI.

I have been following the example from CyAPI Programmer's reference :
