Hi,
I download AN75779 and run SDK 1.3.3.
but fail to build UVC_AN75779.
(I do check the readme.txt of the project. Seems to be build in SDK 1.3.4)
These message is displayed in console.
cc1.exe: error: unrecognized command line option '-std=gnu11'
cs-make: *** [camera_ptzcontrol.o] Error 1
What should i do to build the project?

I am working on a CX3-based product, and I need to provide a unique serial number for each device. I would prefer not to have an additional step during manufacturing which write a unique value into non-volatile memory. Does the CX3 have any sort of unique identifier that I can access through a register that I could use for this purpose?
Thanks.
Show LessI am trying to use the UVC application. We would like to use our vendor ID and product ID and force bind it to the driver. I have edited the cyusb3.inf and added our vendor ID and product ID. But still I am not able to force bind the interrupt to the driver. I have followed all the steps from Cypress Cyusb3.sys Programmer's reference.
Also FX3 is detected twice, one in Imaging devices and in Other devices section
Driver is detected properly in imaging devices section but I am unable to install it in the other devices section.
USB Control Center by Cypress is also not detecting my board.
How can I solve this issue?
Hello,
I have a question about schematic design of SD port power domain.
Our customer's system uses the UHS-I SD memory card. I heard that the UHS-I SD memory card uses 3.3V signal voltage at initialization and then shifts to 1.8V.
How do I switch the I/O voltage in FX3S (or SD3)?
Does FX3S (or SD3) dynamically switch the I/O voltage?
Or is it necessary to switch the power supply circuit from 3.3 V to 1.8 V externally?
Please share the reference circuit diagram of FX3S (or SD3).
I accessed http://www.pactronstore.com/ but I could not access it due to a security warning.

Show LessHello
Please recommend if there are any reference design of a USB bridge design that can connect 2 USB 3.0 host controller?
Communication: USB3.0 (SS)
Eg.

Show LessI purchased the cyusb3kit-003 board.
However, if you try to download the IMG file to the I2C EEPROM of the board through the USB Control Center, the message "Programming of I2C EEPROM Failed" will appear and the download will fail.
When connecting USB to PC, "Cypress FX3 USB BootLoader Device" is connected.
Pmode (J4) Jump is shorted.
Show LessHi,
I would like to step through the example firmware for EZUSB explorer kit.
If I just connect PC to the USB2.0 port on EZUSB and run CYPRESS EZ USB suite, is it enough to do this? If not, what other hardware/software tools do I need?

Show LessI am recently starting working on FX3 SPI code. This is a function in all of SPI code (UsbSpiDmaMode, UsbSpiGpioMode and UsbSpiRegMode). Basically this CyFxUSBSetupCB() function is a call back routine to process control end point 0 data and process. Following code is switching the vendor command.
In the READ command, the code zero out the glEp0Buffer then pass to CySpiTransfer for SPI transfer. Instead of zero out the buffer, the code should get data from EP0 then pass for passing.
I am just wondering how Cypress QA the code before publish.
CyBool_t
CyFxUSBSetupCB (
uint32_t setupdat0,
uint32_t setupdat1)
{
...
case CY_FX_RQT_SPI_FLASH_WRITE:
status = CyU3PUsbGetEP0Data (wLength, glEp0Buffer, NULL);
if (status == CY_U3P_SUCCESS)
{
status = CyFxSpiTransfer (wIndex, wLength, glEp0Buffer, CyFalse);
}
break;
case CY_FX_RQT_SPI_FLASH_READ:
CyU3PMemSet (glEp0Buffer, 0, sizeof (glEp0Buffer));
status = CyU3PUsbGetEP0Data (wLength, glEp0Buffer, NULL);
status = CyFxSpiTransfer (wIndex, wLength, glEp0Buffer, CyTrue);
if (status == CY_U3P_SUCCESS)
{
status = CyU3PUsbSendEP0Data (wLength, glEp0Buffer);
}
break;
Thanks,
Dick
Show LessHi all,
I have the CX3 with a MIPI camera module and I can capture images using UVC driver. I'm using the OV5640 example.
I need to send data from a PC to the CX3, I don't know if is it possible in that project, I only can send and receive image parameters, but not and array, is there any way?
Can I configure also the CX3 also like a Virtual COM? (keeping UVC functions)
Regards,
Iban.
Show LessHello
When I use the driver and library for FX3, is its software royalty free?
Even if I do not adopt FX3 chip and only use those software in my products, is its royalty free?
