USB superspeed peripherals Forum Discussions

I have been reading all the documents and examples about FX3 and so far I haven't found any example that I can use directly. Please help me if you have an example that meets our following requirements:

1. We would like to replace a Microchip micro-controller on our products with FX3 in order to gain the supper speed data transfer so FX3 will be the master on this product.

2. GPIF II will be used to retrieve data from a FIFO memory to the FX3 memory and then a head will be added to the buffer. Then FX3 will send the data to USB (or host).

3. FX3 receives the data request command form USB (or host) with the number of bytes to read which may vary from 16 to 32KB.

4. The FIFO memory control is pretty simple: D15..D0, CS# and RD# lines.

Hopefully some can provide an example.

Thank you in advance.

My image sensor produces 12-bit image intensity data. I would like to be able to selective, through software, capture either the full 12 bits, or just the most-significant 8 bits. I am looking for a good solution to implement this. I wish to avoid using the CPU to rearrange bits for me. What is the best way to do this?

first, i want to know if CYUSB3014 can output clock to the external sensor as FX2LP...

second, when i use GPIF Communicate with external sensor, Does it need to be synchronized with the external device clock....

thanks!!

I successfully download a firmware to the I2C EEPROM accompanying the FX3 device using console center.

However, I fail in dowload a new firmwaire to this I2C EEPROM. The console center prompt a message to remind me reset the device and then dowload. I reset the device by clicking the button "reset device"at the Upper-Right cornner of the console center. And then click the menu program->FX3->download to EEPROM. It still prompt message remind me reset the device. The dialog to choose image file does not simply apppear.

Is it because I do not properly reset the device? I have powered off the system and it still reminds me to reset device.

What kind of reset should be used in this case?

Full reset or just put the program counter to zero?

My final question is how can I update the firmware contained in the EEPROM?
