Is there any important GPIO pins in CYUSB3065-BZXI that should not be left floating? 

especially these - 

CX3_GPIO23

CX3_GPIO44

CX3_GPIO18

CX3_GPIO24

CX3_GPIO45

Hi guys,

How do I build a library for a custom sensor, from scratch? (Such as the one  for the OV5640 in the SDK)

Thanks!

Hi,

I am looking into the possibility of each CX3 device having some unique ID stored at some fixed addresses. I followed the below thread but on two devices I got the same values. I read data from  0xe0055010 and 0xe0055014 but two devices returned 00 00 00 0F 00 00 0F 13. 

Are the addresses are correct? I am using the CYUSB3065 chip.

Below is a code snippet of how I am reading ID in firmware.

int *ptrLSB = (int*)0xE0055010;
int *ptrMSB = (int*)0xE0055014;
abI2CReadRsp[1] = *(ptrMSB + 3);
abI2CReadRsp[2] = *(ptrMSB + 2);
abI2CReadRsp[3] = *(ptrMSB + 1);
abI2CReadRsp[4] = *(ptrMSB);
abI2CReadRsp[5] = *(ptrLSB + 3);
abI2CReadRsp[6] = *(ptrLSB + 2);
abI2CReadRsp[7] = *(ptrLSB + 1);
abI2CReadRsp[8] = *(ptrLSB);

• I have a CYUSB303X with the GPIF-II interface connected to AD7381-4 ADC. The CYUSB is running the attached AD7381-4_cyfxgpiftousb project.
• When applying constant voltage on the GPIF pins, I'm able to read them properly at the USB port (on the host PC).
• When the AD7381-4 digital signals are applied, the readings are always zero (which doesn't correspond to the real data being transmitting). What is the reason for that?

Please see the schematic below:

Here are the signals captured by a logic analyzer, they are always read as zeros, if a DC (Zero or 1) is applied on the GPIF input lines, it is read properly at the USB:

Here is the USB read:

Hi,

I have generated my own config. file from the Image sensor configuration. I got the below errors when connecting to PC(Windows 10). 

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

For your reference, pls find the attached file and device descriptor(.zip file)CX3 Connectivity error

We've been looking through the EZ-USB FX3 SDK and cannot find any VHDL or Verilog files. 

The application notes seem to refer to them, but there doesn't appear to be any other downloads.

The main file in question is "Fx3_slaveFIFO2b_altera".

Is there any way to get this file?

Thanks,

Sam

I am running into strange issues where if I insert Type C USB3.0 on one side CX3-UVC camera is detected. But if a change in the orientation of the cable device is not detected. Please find below sch for reference. Also in older PCB with the same design, we are not facing issues. We have followed guidelines with each PCB. We are not sure what could be the reason.
