5.3.1 – Page 137 to Page 138 : ATmega16U2 ICSP Connection
The procedure for connecting the ISP plug of a USB programmer into the ICSP header for the ATmega16U2 on an Arduino Uno follows. This is described in section 5.3.1 Backing up the ATmega16U2 Firmware with Microchip Studio of the Ultimate Arduino Uno Hardware Manual.
Key on ISP Connector Blocks Connection
As can be seen in the image below, the key on the ISP connector of the programmer prevents it from being plugged into the ICSP header for the ATmega16U2 on an Arduino Uno.
Wires Used for Connection
Six wires that have a single pin male connector on one end and single pin female connector on the other end can be used to connect the ISP plug to the Arduino Uno ATmega16U2 ICSP header. The wires can be seen in the image below.
Plug the Wires into the ISP Plug
Plug the wires, three at a time, into the ISP Plug as the image below shows.
Plug the Wires into the ICSP Header
Now plug the extension wires from the ISP plug to the ICSP header.
The next image shows the extension wires connecting from the ISP plug of the USB programmer to the ICSP header for the ATmega16U2 on an Arduino Uno.
A close-up of the connection can be seen in the following image.
