it's now able to detect the vendor ID and product ID but the Flip software still display "Cannot open port". Please could you specify the device number, the FLIP version, and the USB driver that you are using. I have just downloaded Flip 3.2.0 which comes with a new Jungo driver. I can communicate with a AT89C5131-IL quite happily at 3.3V Vcc. Please can you also quote the response from UsbView. If the 5131 is running a USB application then obviously it will give a different Vendor ID and Product ID. This is what Usb View returns for my chip in bootloader mode: Device Descriptor: bcdUSB: 0x0110 bDeviceClass: 0xFE bDeviceSubClass: 0x01 bDeviceProtocol: 0x00 bMaxPacketSize0: 0x20 (32) idVendor: 0x03EB (Atmel Corporation) idProduct: 0x2FFD bcdDevice: 0x0000 iManufacturer: 0x00 iProduct: 0x00 iSerialNumber: 0x00 bNumConfigurations: 0x01 ConnectionStatus: DeviceConnected Current Config Value: 0x01 Device Bus Speed: Full Device Address: 0x01 Open Pipes: 0 David. |
