USB Low-Full-High Speed Peripherals

New Contributor II

Hi,

i run the bulkloop example on my CY7C68013a Lcsoft board, which was fine.

(removed the 7-seg display code)

then loaded cystream.hex into ram...ok.

Windows device manager shows "Cypress FX3 USB Streamer Example Device" with exclamationmark.

details: device could not be started.

The windows streamer app does not see any device.

 

any idea?

ooh i found it.

one has to remove the i2c display update code as my board is different.

so remove:

// Update the display to indicate the currently selected alt. Interface
if(updateDisplay)
{
EZUSB_WriteI2C(LED_ADDR, 0x01, &(Digit[AlternateSetting]));
EZUSB_WaitForEEPROMWrite(LED_ADDR);
updateDisplay = FALSE;
}

Well...a bit early.

I programmed the cystream.hex to RAM and it came up as a "Cypres FX3 USB StreamerExample Decice"

with exclamationmark in devicemanager. (VID:0x04B4 PID:0x00F1)

The PID changed.

Do i need a special driver for this cystream example?
