USB superspeed peripherals Forum Discussions
Hi,
We are trying to transmit data from UART code (provided by cypress) to our customized CyU3FX3s (3035 part number) board. We are unable to see the data transmitted on the UART Tx pin when connected to oscilloscope.
Thanks in Advance.
Hi all,
I'm trying to design a device with 3 interfaces. I read all info available and write a USB descriptors , but USB control center do not recognize the device at all. Can anybody can find the problem ???
Show Lesshello,anyone may tell me how to change the AN75799 UVC DMA buffer size to 64k?
Hello ,
Is there any way to change DataBus GPIO's?
GPIF II only allow me to change data bus width (8/16/24/36 bits).
My point is to make 8bit bus but from GPIO 8:15 not 0:7 is there any way to change it? Or I need to use some hardware to swap bits?
Regards,
Mikołaj

if yes, can you send source code?
Hello,
For one of our project, we are keen to use the FX3 chip and the GPIF engine to send/receive data on two parallel bus.
My question is as follow: is it possible to create a 24 bits data bus and use the 12 lower bits (from 0 to 11) to push data on bus and use the 12 upper bits (12 to 23) to retrieve data from bus ? The idea is to use the GPIF as an aggregator of the two concurrent 12 bits data path through a single USB port.
Best regards,

I want to setup a multi channel DMA.One producer to multi consumers with manual mode.
How do I choice which consumer that I want to commit in my callback function ?
Producer : CY_U3P_PIB_SOCKET_0
Consumers : CY_U3P_UIB_SOCKET_CONS_2 CY_U3P_UIB_SOCKET_CONS_9
Thank you!!
Show LessIn USB3 devices, are the USB3 lines and USB2 lines completely separate ? Can a USB3 chip work in USB3 mode with only RX/TX connected and not D+/D- ? I'm asking if it's possible to do the following:

I know that for sure both devices will work in USB2-only mode just fine, but will the FX3 chip in such a connection work in USB3 mode also ? Or is there signaling on the USB2 lines, even in USB3 mode, that requires there be a direct connection ?
Show LessHi,
I'm currently trying to use the FX3 SUPERSPEED EXPLORER KIT before designing a custom board with the FX3 component.
I'm using Windows and I'm trying to compile the UsbUart project but I can't compile it. I actually get the following error in the Cypress EZ USB Suite :
cs-make: *** [cyfx_gcc_startup.o] Error 1
I installed both EZ-USB FX3 SDK 1.3.3 and Superspeed Explorer Kit Rev (both with the complete setting chosen) but it doesn't work.
Could you please help to solve my problem ?
I got another question : the UsbUart example is described as an USB to UART bridge. Does it mean that I can directly plug the wires of a UART interface from a microcontroller and I would be able to use HyperTerminal to communicate with it without any extra setup ? Does it work "out of the box" ?
Thanks in advance for the feedback.
