Hi sir,

FX3 Serial number

i am looking for a way to create a unique serial number for each camera.. i was referring above link and tried to apply to my cx3 device..  got a question..

In the example firmware named Cx3UvcOV5640.img    i could not find characters like 0x43, 0x00, 0x41 and 0x00 in the firmware file.. should i add this string manually?

or

there is a different string for CX3 device??

thanks

CHEN

Hello,

As the links indicates, you could invoke API

CyU3PReturnStatus_t CyU3PReadDeviceRegisters ( uvint32_t regAddr, uint8_t numRegs, uint32_t dataBuf)

to read register 0xE0055010. The value returned byt this API is unique.

Hi, Yang

0xE0055010 stores special data?

If the 8 bytes serial number follows any rule? Can I generate a fake 8-byte number to the host?

Because my host not response to my 0xE0055010's data.

Tks a lot!

As I mentioned before, the value returned by that API(reading reg 0xE0055010) is unique.

The content in that register is generated in some rules. You could also write your own code to generate the serial number in firmware.
