Make sure to power the Arduino as ISP by connecting it to your computer. Or, if you're using the Arduino as your programmer, it should look the image below. Since the programmer is not able to provide power to the target, you would need an additional cable connected to the target AVR.Ĭlick for larger image. As you can see, the position of the AVR cable is connected to the RedBoard similar to the image with the AVR MKII. The image below shows the Atmel JTAG ICE3 connected to a RedBoard. The same goes for newer Atmel programmers. Thus, a cable is required to connect to the target AVR. However, the official Atmel AVR MKII is not able to provide power to the target board. Since the pocket AVR programmer can provide 5V power to the target AVR with the switch flipped to the Power Target position, a USB cable is not needed for the RedBoard. You also might notice that there is not a USB cable connected to one of the RedBoards. The AVR MKII's cable has MISO connected closer toward the outside of the cable. As shown in the image below with MISO highlighted by a white dot, the pocket AVR programmer's cable has MISO connected closer toward the inside of the cable. Congratulations! You have successfully uploaded your first sketch to your board.Heads up! There is a subtle difference in the orientation of the 2x5 to 2x3 AVR programming cable compared to other 2x3 cables that are attached to official Atmel programmers.The LED labeled L near pin 13 should now blink slowly.Wait for the “Done uploading” message in the bottom blue status bar.Upload the sketch: File > Upload to I/O Board. ![]() If you do not know which one this is, you can find out by going into Device Manager > Ports (COM & LPT), and look for a “USB Serial Port (COMx)” This is the serial port for the board’s built-in FTDI.
