HI， I cannot  search the source about  USB3 vision。

U3Vbootloader, U3V-controller..

Hi,

I am using UVC code provided by Cypress and I can take an image with 640*512 camera in YUY2.

I am using an FPGA to get codes from I2C but no SCK and SDA signals generated by Cypress Device,  although it is wrtten that 'BULK IN or BULK OUT process is

succesful' on Control Center.

Also, I sometimes get error 997 when I want to use USB_DEBUG_INTERFACE of UVC code.

In document AN75779 there is no clear explanation how I2C sends data to device which is not MT9M114.

Can anyone help me on this issue? Also, knowledge about SPI and UART with bulk communcation also will be very helpful for me.

Thanks.

Hello,

I am debugging an I2C Implementation in hardware, with an OV5640 MIPI Camera.

My goal is to see whether the MIPI Camera responds to I2C communication from the CX3.

I know the default slave ID of the OV5640 camera, and the registers which I would like to inspect, namely device ID registers.

I have taken a look at the USBI2CRegMode and CX3UVCOV5640 code, and cannot locate any slave ID settings for the I2C bus in code.

Can anyone point me to documentation which discusses how to send and receive inputs from the I2C bus? I have only been able to find the CX3OV5640 API documentation, which only allows for initialization which returns a void, and UVC controls.

Thank you kindly.

I wonder how to specify a specific thread in FX3 firmware by using 'BeginDataXfer()' in order to send/receive data.

I've prepared three threads in FX3 GPIF-II, thread 0 for USB-to-FX3, thread 1 for USB-to-FX3, and thread 2 for FX3-to-USB.

So that I need to set one of thread 0 or thread 1 to send data to FX3.

The CyAPI manual seems a bit primitive so it is hard to figure out how to do.

Are there any example code for FX3 firmware and CyAPI Application to do the above transfer?

Or, are there any document regarding this?

Thanks in advance.

Ando.

Hi,

what is the difference between in implementing mass storage and vendor class?

any documents related to it?please provide me.

thank you.
