Hi, I've enabled the Exposure Time(Absolute) in USB Camera Terminal Descriptor & corresponding FW code, and it worked.
I tried to add Auto Exposure Mode. Therefore I added it in USB Camera Terminal Descriptor & corresponding FW code.
Refer UVC spec:
Because I only enabled the Exposure Time(Absolute) ability before, I thought I should use "D3: Aperture Priority Mode".
Thus, I set auto_exposure_mode variable = 0x08(0b00001000) in UVCHandleCameraTerminalRqts().
The ability was available. And the default status enable Auto Exposure. That's what I need.
If I disabled the check button , the FW received the CY_FX_USB_UVC_GET_CUR_REQ & CY_FX_USB_UVC_SET_CUR_REQ requests.
However, if I enable the check button, the FW only received the CY_FX_USB_UVC_GET_CUR_REQ request, but don’t receive CY_FX_USB_UVC_SET_CUR_REQ request.
I need the CY_FX_USB_UVC_SET_CUR_REQ request to enable my auto exposure mechanism.
Is there any incorrect in my setting for case CY_FX_UVC_CT_AE_MODE_CONTROL(second image)?
Any help will be highly appreciated!
Show Lessi want to use cy3014 to control my FPGA PS configure sequence
i want to control spi flash output FPGA config data (MISO connect with FPGA data pin too)
and i dont need the data in fx3 program,
i try to use null pointer in the spi_recv function return null pointer error
also use small buff the programe keep restart itself

Hi,
I am developing an oscilloscope in-house. Currently, I am working on the Texas Instrument's ADS54J60evm and TSW14J56evm boards. My end goal is to display and format at least 500K samples captured.
Now, I had been using HSDC GUI to display the captured data from the TSW board; but due to fairly low number of samples displayed on HSDC GUI, I need to switch to a custom based GUI.
So, my first step is to capture the data from the CYUSB301X available on the TSW14J56evm board. Is it possible if you can share with me the python files or the way CYUSB301X is sending the data to the HSDC GUI?
Thanks.
Show Lesshello,
I created a CX3 project, I observed the sensor output with an oscilloscope, and my sensor configuration was successfully able to output the expected data and clock.
But the interface where CX3 parses the data is not connected and there is no way to view the hysn vysn signal.
Now I can use JLINK for single step debugging, but I want to view the uart log, I want to know if I can view it with jlink? Or is there another way?
I also downloaded Tera term but it doesn't have any information

Hello
I currently have a CX3 project configured, I downloaded it to the CX3 hardware and started the CP camera, the camera's still image and Video icons kept switching automatically and finally it showed that the camera switch failed.
I would like to know what is the reason for this, I have only modified the sensor.c file for the whole project,Looking forward to your help.
Hello we are using CX3 RDK board receive a RAW 10bit MIPI sensor Input, We made the configuration as shown below
In the image configuration , the necessary I2C details has been entered
When programmed the CX3-RDK board enumerates as CX3 UVC device, but when we probe the i2c lines of sensor no values is being written from CX3. Are we missing something?

I have a basic setup working great with the FX3 when operating in synchronous master mode with internal clock settings. But, my data source always has the clock running from the start, so PCLK is always receiving a clock and data.
GPIF Settings:
(Master/Slave) Either causes crash
(Synchronous)
(External Clock)
The moment the GPIF bus is loaded, the processor freezes. Sometimes it gets as far as calling a `CYU3P_PIB_INTR_DLL_UPDATE` before freezing. It's always after load. I've tried springboarding into a loop of DATA_IN that doesn't actually write the data but nothing I do seems to prevent the device from freezing except discontinuing the clock.
Is there a way to suppress the PCLK pin until everything else is setup and ready to roll, like the state machine is started? Or anything else I can do to prevent the chip from seizing up when unsolicited data is flowing in?
BTW - as soon as I switch around to internal clock writing out, everything works 100% as expected.

Thanks,

what is the recommendation design/connections for FX3 with a Type-C receptacle when using a USB 3.1 Type-A to Type-C cable to connect from PC host to FX3? Basically we just need FX3 able to transfer data between PC Host and the FX3 board device with using Type-A to Type-C cable.
