Electronic – Arduino with FTDI cable – USB port error

arduinoftdi

This is my first time using FTDI with Arduino.

I'm using the SparkFun EL Sequencer which uses and embedded ATMega328p. I hooked it up to my USB port using this FTDI cable. When I try to upload my code: I get the following error:

avrdude: stk500_getsync(): not in sync: resp=0x00

Debug mode:

avrdude: usbdev_open(): did not find any USB device "usb"

I've used my regular USB cable to successfully program my UNO from this machine (Win 7) before. No problem there.

With the sequencer I see the machine detecting a connection on COM 7 when I plug in the new device. I've tried pressing RESET on the Arduino prior to uploading, which I've seen in some other posts.

Am I missing something here? The description of the cable seems to imply that I don't need any other hardware.

Best Answer

There is an error on the El Sequencer board silk-screen - the pins on the FTDI cable are reversed.
