USB low-full-high speed peripherals Forum Discussions

Hi,

I would like to do the following with a CY7C68013A-100AXC (100 pin FX2LP):

1. Connect to USB and power up

2. Enumerate with default, download firmware and descriptor tables, reenumerate

3. Configure the device in port mode and use ports A through E as 40 GPIO pins

4. Set some IO pins, read some IO pins, do some stuff (ports A, C and E always as outputs, ports B and D as I/O)

5. Configure the device as GPIF master (just port B and D, no GPIF address pins needed), while keeping ports A, C and E as outputs (Is it possible that ports A, C and E keep their output states without glitches when switching ports B and D from GPIO to GPIF?)

6. Stream out 16 bit data through GPIF on ports B and D with 5 MHz external clock for up to 100 seconds without losing data (10MByte/sec, up to 1Gbyte of data)

7. Switch back to all port mode while keeping at least the outputs at ports A, C and E unchanged

8. Set output values of ports B and D

9. Go in suspend mode while keeping all port outputs active in their state before entering suspend mode

10. Wake up the device some minutes or hours later via USB

Would this be possible or is there any difficulty?

I would like to send up to 8 bytes of data in control command to FX2 using additional data field. Up to four bytes the mValue and mIndex field can be used but for more, additional data field is needed.

What is the location of the received bytes?

Does the square pad on the back side of the QFN package need to be connected to ground?

I'm playing with you design kit and want to ensure I get the design right. . .

Thanks

Hello,

The USB-Serial Configuration Utility allows to select Baud rate of up to 3000 kbps in UART mode, but the maximum communication rate of the USB serial port that can be selected on the Windows Device Manager is 128 kbps.

This meaning supports 3Mbps as the communication specification on the SCB side of CY7C65211, but can the USB side (COM port driver) support up to 128 kbps only?

I am trying to use the CY_FX2LP_LGS_ DMB-TH_TV Dongle example to read an MPEG2 stream using FX2LP Ez USB. But there is file InitFrontend.h that is missing and I am not sure where to find it. I have tried looking online but had no luck. Can anyone please point me to the right location to download the file.

Hi

I just bought the CY7C68013 baord. I am able to load a hex file onto the ram and the eeprom using the USB control center. Whne I try to build the default Keils Projects which use the EZUSB and USBJmpTb I get the the foollowing bult time errors

FATAL Error L220: Invalid Input Module

And the modules are the two files mentioned above.

I am not sure how to proceed and any help will be appreciated
