Programming
The Arduino Uno can be programmed with the (Arduino Software(IDE)). Select Arduino/Genuino Uno from the ToolsBoard menu (according to the microcontroller on your board). For details, see thereferenceandtutorials.
The ATmega328 on the Arduino Uno comes preprogrammed with abootloaderthat allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference,C header files).
You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header usingArduino ISPor similar; seethese instructionsfor details.
The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository. The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be activated by:
On Rev1 boards: connecting the solder jumper on the back of the board (near the map of Italy) and then rese ing the 8U2.
